# Objective
Add examples for manipulating sprites and meshes by either mutating the
handle or direct manipulation of the asset, as described in #15056.
Closes#3130.
(The previous PR suffered a Git-tastrophe, and was unceremoniously
closed, sry! 😅 )

# Objective
Closes#11825
## Solution
Change return type of `get_resource_ref` and `resource_ref` from `Res`
to `Ref` and implement `From Res<T> for Ref<T>`.
# Objective
Fixes#15330
## Solution
1. Add an `ExtractTextureSlice` variant to `RenderUiSystem`.
2. Add `RenderUiSystem::ExtractTextureSlice` to the `ExtractSchedule`
between `ExtractImages` and `ExtractBorders`.
3. Add `extract_ui_texture_slices` to the new `ExtractTextureSlice`
system set.
Which results in texture slice nodes being extracted before borders. No
more z-fighting, borders will always be drawn on top of texture-sliced
images.
# Objective
> Rust 1.81 released the #[expect(...)] attribute, which works like
#[allow(...)] but throws a warning if the lint isn't raised. This is
preferred to #[allow(...)] because it tells us when it can be removed.
- Adopts the parts of #15118 that are complete, and updates the branch
so it can be merged.
- There were a few conflicts, let me know if I misjudged any of 'em.

# Objective
There may be times where a function in the `FunctionRegistry` doesn't
need to be fully retrieved. A user may just need to call it with a set
of arguments.
We should provide a shortcut for doing this.
## Solution
Add the `FunctionRegistry::call` method to directly call a function in
the registry with the given name and arguments.
## Testing
You can test locally by running:
```
cargo test --package bevy_reflect --all-features
```
No hard feelings if you don't want to make this change. This is just
something I stumbled over in my very first read of the `bevy_ecs` crate.
# Objective
- the general goal here is to improve DX slightly
- make the code easier to read in general. The previous names make the
code harder to read, especially since they are so similar.
## Solution
- choose more specific names for the fields
- `index_iter` -> `freelist_indices` : "freelist" is a well established
term in the rest of the docs in this module, so we might want to reuse
it
- `index_range` -> `new_indices` : Nothing besides the doc comment
stated that these indices were actually new/fresh
## Testing
Note that the fields are private so that this is no breaking change.
They are also only used in this one module.
# Objective
- Fixes#15319
- Fixes#15317
## Solution
- Updated CI task to check for _any_ `bevy_*` crates, rather than just
`bevy_internal`
---------

# Objective
- Intended to resolve https://github.com/bevyengine/bevy/issues/15290.
- Fix four duplicate `DragEnd` firing when drag finished.
- Fix redundant `DragStart` firing when dragging across pick-able
entities.
- Fix `Click` coming after `Drop` and obliterating finished drag
interactions.
Big thanks to B. Reinhart for testing picking in their codebase and
identifying these issues early.
## Solution
- Fix press & drag state being cleared after the first entity is read
from the hover map on pointer release, rather than after all entities
are read. This caused only the first hovered entity to receive `Up` and
`Click` events.
- Fixes `Down` being determined using the `previous_hover_map` rather
than `hover_map`, a regression compared to `bevy_mod_picking`. I think
this is what was messing up drag events.
- Fixes and issue where `PointerEnd` would fire multiple times and
`PointerStart` would fire when dragging onto a new entity.
- Re-orders events to make them easier to handle. `Out` now fired before
`DragLeave` and `Click/Up` now fire before `DragDrop`.
- Generally refactors the picking event code to be more clean and sane.
## Testing
These changes are currently sporadically tested.
# Objective
- Remove an int2ptr cast in `bevy_ptr::dangling_with_align`
- This is flagged by MIRI unless `-Zmiri-permissive-provenance` is used
(like in CI)
- Remove `-Zmiri-permissive-provenance` in CI
## Solution
- Create the raw pointer like
[`std::ptr::without_provenance`](https://doc.rust-lang.org/stable/std/ptr/fn.without_provenance_mut.html)
does, i.e. by starting from a null pointer.

# Objective
- The multithreaded executor has some weird UB related to stacked
borrows and async blocks
- See my explanation on discord
https://discord.com/channels/691052431525675048/749335865876021248/1286359267921887232
- Closes#15296 (can this be used to close PRs?)
## Solution
- Don't create a `&mut World` reference outside `async` blocks and then
capture it, but instead directly create it inside the `async` blocks.
This avoids it being captured, which has some weird requirement on its
validity.
## Testing
- Added a regression test
Added a `HeadlessPlugins` plugin group, that adds more default
functionality (like logging) than the `MinimumPlugins`. Fixes#15203
Changed the headless example to use the new plugin group.
I am not entirely sure if the list of plugins is correct. Are there ones
that should be added / removed?
----
The `TerminalCtrlCHandlerPlugin` has interesting effects in the headless
example: Installing it a second time it will give a log message about
skipping installation, because it is already installed. Ctrl+C will
terminate the application in that case. However, _not_ installing it the
second time (so only on the app that runs once) has the effect that the
app that runs continuously cannot be stopped using Ctrl+C.
This implies that, even though the second app did not install the Ctrl+C
handler, it did _something_ because it was keeping the one from the
first app alive.
Not sure if this is a problem or issue, or can be labeled a wierd quirk
of having multiple Apps in one executable.
# Objective
- I was running miri locally to check the UB in #15276 and it detected
an unrelated memory leak, due to the `RawCommandQueue` changes. (I
probably should have turned the leak detection off because we do
purposely leak interned string labels and I assume that's why CI didn't
detect it.)
## Solution
- The memory allocated to `RawCommandQueue` needs to be manually
dropped. This was being done for `bytes` and `cursor`, but was missed
for `panic_recovery`.
## Testing
- Ran miri locally and the related memory leaks errors when away.
`ShortName` is lazily evaluated and does not allocate, instead providing
`Display` and `Debug` implementations which write directly to a
formatter using the original algorithm. When using `ShortName` in format
strings (`panic`, `dbg`, `format`, etc.) you can directly use the
`ShortName` type. If you require a `String`, simply call
`ShortName(...).to_string()`.
# Objective
- Remove the requirement for allocation when using `get_short_name`
## Solution
- Added new type `ShortName` which wraps a name and provides its own
`Debug` and `Display` implementations, using the original
`get_short_name` algorithm without the need for allocating.
- Removed `get_short_name`, as `ShortName(...)` is more performant and
ergonomic.
- Added `ShortName::of::<T>` method to streamline the common use-case
for name shortening.
## Testing
- CI
## Migration Guide
### For `format!`, `dbg!`, `panic!`, etc.
```rust
// Before
panic!("{} is too short!", get_short_name(name));
// After
panic!("{} is too short!", ShortName(name));
```
### Need a `String` Value
```rust
// Before
let short: String = get_short_name(name);
// After
let short: String = ShortName(name).to_string();
```
## Notes
`ShortName` lazily evaluates, and directly writes to a formatter via
`Debug` and `Display`, which removes the need to allocate a `String`
when printing a shortened type name. Because the implementation has been
moved into the `fmt` method, repeated printing of the `ShortName` type
may be less performant than converting it into a `String`. However, no
instances of this are present in Bevy, and the user can get the original
behaviour by calling `.to_string()` at no extra cost.

# Objective
It's convenient to be able to modify a component if it exist, and insert
a default value if it doesn't. You can already do most of this with
`EntityCommands::insert_if_new`, and all of this using a custom command.
However, that does not spark joy in my opinion.
Closes#10669
## Solution
Introduce a new commands type `EntityEntryCommands`, along with a method
to access it, `EntityCommands::entry`.
`EntityEntryCommands` exposes a subset of the entry API (`and_modify`,
`or_insert`, etc), however it's not an enum so it doesn't allow pattern
matching. Also, `or_insert` won't return the component because it's all
based on commands.
## Testing
Added a new test `entity_commands_entry`.
---
## Showcase
```rust
commands
.entity(player)
.entry::<Level>()
.and_modify(|mut lvl| lvl.0 += 1)
.or_default();
```

[*Percentage-closer soft shadows*] are a technique from 2004 that allow
shadows to become blurrier farther from the objects that cast them. It
works by introducing a *blocker search* step that runs before the normal
shadow map sampling. The blocker search step detects the difference
between the depth of the fragment being rasterized and the depth of the
nearby samples in the depth buffer. Larger depth differences result in a
larger penumbra and therefore a blurrier shadow.
To enable PCSS, fill in the `soft_shadow_size` value in
`DirectionalLight`, `PointLight`, or `SpotLight`, as appropriate. This
shadow size value represents the size of the light and should be tuned
as appropriate for your scene. Higher values result in a wider penumbra
(i.e. blurrier shadows).
When using PCSS, temporal shadow maps
(`ShadowFilteringMethod::Temporal`) are recommended. If you don't use
`ShadowFilteringMethod::Temporal` and instead use
`ShadowFilteringMethod::Gaussian`, Bevy will use the same technique as
`Temporal`, but the result won't vary over time. This produces a rather
noisy result. Doing better would likely require downsampling the shadow
map, which would be complex and slower (and would require PR #13003 to
land first).
In addition to PCSS, this commit makes the near Z plane for the shadow
map configurable on a per-light basis. Previously, it had been hardcoded
to 0.1 meters. This change was necessary to make the point light shadow
map in the example look reasonable, as otherwise the shadows appeared
far too aliased.
A new example, `pcss`, has been added. It demonstrates the
percentage-closer soft shadow technique with directional lights, point
lights, spot lights, non-temporal operation, and temporal operation. The
assets are my original work.
Both temporal and non-temporal shadows are rather noisy in the example,
and, as mentioned before, this is unavoidable without downsampling the
depth buffer, which we can't do yet. Note also that the shadows don't
look particularly great for point lights; the example simply isn't an
ideal scene for them. Nevertheless, I felt that the benefits of the
ability to do a side-by-side comparison of directional and point lights
outweighed the unsightliness of the point light shadows in that example,
so I kept the point light feature in.
Fixes#3631.
[*Percentage-closer soft shadows*]:
https://developer.download.nvidia.com/shaderlibrary/docs/shadow_PCSS.pdf
## Changelog
### Added
* Percentage-closer soft shadows (PCSS) are now supported, allowing
shadows to become blurrier as they stretch away from objects. To use
them, set the `soft_shadow_size` field in `DirectionalLight`,
`PointLight`, or `SpotLight`, as applicable.
* The near Z value for shadow maps is now customizable via the
`shadow_map_near_z` field in `DirectionalLight`, `PointLight`, and
`SpotLight`.

# Objective
- Adjust `bevy_utils` to make it `no_std` compatible
- Partially replaces #6581
- Contributes to #8161
- Contributes to #6370
## Solution
Added `alloc` and `std` features to `bevy_utils` (`std` is enabled by
default), allowing the crate's use in `no_std` contexts.
## Testing
- CI passed locally.
- Used `bevy_utils` in a `no_std` crate as an experiment and compiled
successfully.
## Migration Guide
If you were importing `bevy_utils` and setting `default_features` to
`false`, but relying on elements which are now gated behind the `std` or
`alloc` features, include the relevant feature in your `Cargo.toml`.
## Notes
- Bevy already includes a single `no_std` crate, `bevy_ptr`, so there is
precedent for this change.
- As `bevy_utils` is widely used across the rest of Bevy, further work
to make Bevy `no_std` compatible would be blocked on this crate, if such
work was to be undertaken.
- Most of the changes in this PR are just the removal of an unnecessary
call to `to_string()` within unit tests.
Enabled `check-private-items` in `clippy.toml` and then fixed the
resulting errors. Most of these were simply misformatted and of the
remaining:
- ~Added `#[allow(clippy::missing_safety_doc)]` to~ Removed unsafe from
a pair of functions in `bevy_utils/futures` which are only unsafe so
that they can be passed to a function which requires `unsafe fn`
- Removed `unsafe` from `UnsafeWorldCell::observers` as from what I can
tell it is always safe like `components`, `bundles` etc. (this should be
checked)
- Added safety docs to:
- `Bundles::get_storage_unchecked`: Based on the function that writes to
`dynamic_component_storages`
- `Bundles::get_storages_unchecked`: Based on the function that writes
to `dynamic_bundle_storages`
- `QueryIterationCursor::init_empty`: Duplicated from `init`
- `QueryIterationCursor::peek_last`: Thanks Giooschi (also added
internal unsafe blocks)
- `tests::drop_ptr`: Moved safety comment out to the doc string
This lint would also apply to `missing_errors_doc`, `missing_panics_doc`
and `unnecessary_safety_doc` if we chose to enable any of those at some
point, although there is an open
[issue](https://github.com/rust-lang/rust-clippy/issues/13074) to
separate these options.
# Objective
Make it clear to the user why their program is failing rather than
having an unhelpful `called Option::unwrap() on a None value` message.
## Solution
Change the `unwrap()` calls to `expect()` calls, mirroring previously
implemented error messages.
## Testing
I have not tested these changes, but they are fairly trivial so I do not
necessarily feel they need it.
# Objective
When deriving `Reflect`, users will notice that their generic arguments
also need to implement `Reflect`:
```rust
#[derive(Reflect)]
struct Foo<T: Reflect> {
value: T
}
```
This works well for now. However, as we want to do more with `Reflect`,
these bounds might need to change. For example, to get #4154 working, we
likely need to enforce the `GetTypeRegistration` trait. So now we have:
```rust
#[derive(Reflect)]
struct Foo<T: Reflect + GetTypeRegistration> {
value: T
}
```
Not great, but not horrible. However, we might then want to do something
as suggested in
[this](https://github.com/bevyengine/bevy/issues/5745#issuecomment-1221389131)
comment and add a `ReflectTypeName` trait for stable type name support.
Well now we have:
```rust
#[derive(Reflect)]
struct Foo<T: Reflect + GetTypeRegistration + ReflectTypeName> {
value: T
}
```
Now imagine that for even two or three generic types. Yikes!
As the API changes it would be nice if users didn't need to manually
migrate their generic type bounds like this.
A lot of these traits are (or will/might be) core to the entire
reflection API. And although `Reflect` can't add them as supertraits for
object-safety reasons, they are still indirectly required for things to
function properly (manual implementors will know how easy it is to
forget to implement `GetTypeRegistration`). And they should all be
automatically implemented for user types anyways as long they're using
`#[derive(Reflect)]`.
## Solution
Add a "catch-all" trait called `Reflectable` whose supertraits are a
select handful of core reflection traits.
This allows us to consolidate all the examples above into this:
```rust
#[derive(Reflect)]
struct Foo<T: Reflectable> {
value: T
}
```
And as we experiment with the API, users can rest easy knowing they
don't need to migrate dozens upon dozens of types. It should all be
automatic!
## Discussion
1. Thoughts on the name `Reflectable`? Is it too easily confused with
`Reflect`? Or does it at least accurately describe that this contains
the core traits? If not, maybe `BaseReflect`?
---
## Changelog
- Added the `Reflectable` trait

# Objective
Fixes#15258
## Solution
If my understanding is correct, sprites with NaN anywhere in their
transform won't even get onto the screen, so should not generate pick
events. This PR filters sprites with NaN in their transforms before
sorting by depth, then uses `FloatOrd` to simplify the comparison. Since
we're guaranteed to not have NaN values, it's technically unnecessary,
and we could instead sort with `a.partial_cmp(&b).unwrap()`, or even
`unwrap_unchecked()`.
## Testing
I ran the picking example to ensure Z sorting was working as intended.
# Objective
Asset processing (added as part of #8624) is a powerful, high-impact
feature, but has been widely underused (and underdeveloped) due to poor
developer understanding.
## Solution
In this PR, I've documented what asset processing is, why it's useful,
and pointed users to the two primary entry points.
While I would like substantially more involved practical examples for
how to perform common asset-processing tasks, I've split them out from
this PR for ease of review (and actually submitting this for review
before the weekend).
We should add bread crumbs from the module docs to these docs, but
whether we add that here or in #15056 depends on which gets merged
first.

# Objective
Bevy's asset system is powerful and generally well-designed but very
opaque.
Beginners struggle to discover how to do simple tasks and grok the
fundamental data models, while more advanced users trip over the
assorted traits and their relation to each other.
Reverts #15054 ;)
## Solution
This PR adds module documentation to `bevy_assets`, tweaking the
associated documentation on the items as needed to provide further
details and bread crumbs.
If you have ideas for other important, hard-to-discover patterns or
functionality in this crate, please let me know.
That said, I've left out a section on asset preprocessing which *should*
eventually go here. That is substantially more uncertain, and requires
both more time to investigate and more expertise to review.

# Objective
Two of the `IntoSystemConfigs` `impl`s are out of place near the top of
the file.
## Solution
Put them below the `IntoSystemConfigs` trait definition, alongside the
other `impl`.
# Objective
Fixes#15223
## Solution
Adds an `enabled` flag to the `FpsOverlayConfig` resource with a system
that detects it's change, and adjusts the visibility of the overlay text
entity.
## Testing
I extended the `fps_overlay` example with the option to toggle the
overlay. Run with:
```
cargo run --features="bevy_dev_tools" --example fps_overlay
```
This commit adds two new `WorldQuery` types: `EntityRefExcept` and
`EntityMutExcept`. These types work just like `EntityRef` and
`EntityMut`, but they prevent access to a statically-specified list of
components. For example, `EntityMutExcept<(AnimationPlayer,
Handle<AnimationGraph>)>` provides mutable access to all components
except for `AnimationPlayer` and `Handle<AnimationGraph>`. These types
are useful when you need to be able to process arbitrary queries while
iterating over the results of another `EntityMut` query.
The motivating use case is *generalized animation*, which is an upcoming
feature that allows animation of any component property, not just
rotation, translation, scaling, or morph weights. To implement this, we
must change the current `AnyOf<(&mut Transform, &mut MorphWeights)>` to
instead be `EntityMutExcept<(AnimationPlayer, Handle<AnimationGraph>)>`.
It's possible to use `FilteredEntityMut` in conjunction with a
dynamically-generated system instead, but `FilteredEntityMut` isn't
optimized for the use case of a large number of allowed components
coupled with a small set of disallowed components. No amount of
optimization of `FilteredEntityMut` produced acceptable performance on
the `many_foxes` benchmark. `Query<EntityMut, Without<AnimationPlayer>>`
will not suffice either, as it's legal and idiomatic for an
`AnimationTarget` and an `AnimationPlayer` to coexist on the same
entity.
An alternate proposal was to implement a somewhat-more-general
`Except<Q, CL>` feature, where Q is a `WorldQuery` and CL is a
`ComponentList`. I wasn't able to implement that proposal in a
reasonable way, because of the fact that methods like
`EntityMut::get_mut` and `EntityRef::get` are inherent methods instead
of methods on `WorldQuery`, and therefore there was no way to delegate
methods like `get` and `get_mut` to the inner query in a generic way.
Refactoring those methods into a trait would probably be possible.
However, I didn't see a use case for a hypothetical `Except` with
arbitrary queries: `Query<Except<(&Transform, &Visibility),
Visibility>>` would just be a complicated equivalent to
`Query<&Transform>`, for instance. So, out of a desire for simplicity, I
omitted a generic `Except` mechanism.
I've tested the performance of generalized animation on `many_foxes` and
found that, with this patch, `animate_targets` has a 7.4% slowdown over
`main`. With `FilteredEntityMut` optimized to use `Arc<Access>`, the
slowdown is 75.6%, due to contention on the reference count. Without
`Arc<Access>`, the slowdown is even worse, over 2x.
## Testing
New tests have been added that check that `EntityRefExcept` and
`EntityMutExcept` allow and disallow access to components properly and
that the query engine can correctly reject conflicting queries involving
those types.
A Tracy profile of `many_foxes` with 10,000 foxes showing generalized
animation using `FilteredEntityMut` (red) vs. main (yellow) is as
follows:

# Objective
- Fixes#15106
## Solution
- Trivial refactor to rename the method. The duplicate method `push` was
removed as well. This will simpify the API and make the semantics more
clear. `Add` implies that the action happens immediately, whereas in
reality, the command is queued to be run eventually.
- `ChildBuilder::add_command` has similarly been renamed to
`queue_command`.
## Testing
Unit tests should suffice for this simple refactor.
---
## Migration Guide
- `Commands::add` and `Commands::push` have been replaced with
`Commnads::queue`.
- `ChildBuilder::add_command` has been renamed to
`ChildBuilder::queue_command`.
# Objective
Currently the resource doesn't get dropped if thread panics. This is
presumably to prevent !SEND resource from being dropped by wrong thread.
But, this logic is not needed for SEND resources. So we don't need this
check for SEND resource.
Fixes#15144
## Solution
We check if resource is !SEND before, validating that correct thread is
dropping the resource.
## Testing
- Did you test these changes? If so, how?
I did run cargo test on bevy.
- Are there any parts that need more testing?
No
- How can other people (reviewers) test your changes? Is there anything
specific they need to know?
Nothing special
- If relevant, what platforms did you test these changes on, and are
there any important ones you can't test?

# Objective
- Makes naming between add_child and add_children more consistent
- Fixes#15101
## Solution
renamed push_children to add_children
## Testing
- Did you test these changes? If so, how?
Ran tests + grep search for any instance of `push_child`
- Are there any parts that need more testing?
- How can other people (reviewers) test your changes? Is there anything
specific they need to know?
- If relevant, what platforms did you test these changes on, and are
there any important ones you can't test?
ran tests on WSL2

## Migration Guide
> This section is optional. If there are no breaking changes, you can
delete this section.
- If this PR is a breaking change (relative to the last release of
Bevy), describe how a user might need to migrate their code to support
these changes
rename any use of `push_children()` to the updated `add_children()`
# Objective
Currently, UI is always rendered with anti-aliasing. This makes bevy's
UI completely unsuitable for art-styles that demands hard pixelated
edges, such as retro-style games.
## Solution
Add a component for disabling anti-aliasing in UI.
## Testing
In
[`examples/ui/button.rs`](15e246eff8/examples/ui/button.rs),
add the component to the camera like this:
```rust
use bevy::{prelude::*, ui::prelude::*};
commands.spawn((Camera2dBundle::default(), UiAntiAlias::Off));
```
The rounded button will now render without anti-aliasing.
## Showcase
An example of a rounded UI node rendered without anti-aliasing, with and
without borders:
# Objective
- Another way of specifying rotations was requested in
https://github.com/bevyengine/bevy/issues/11132#issuecomment-2344603178
## Solution
- Add methods on `Rot2`
- `turn_fraction(fraction: f32) -> Self`
- `as_turn_fraction(self) -> f32`
- Also add some documentation on range of rotation
## Testing
- extended existing tests
- added new tests
## Showcase
```rust
let rotation1 = Rot2::degrees(90.0);
let rotation2 = Rot2::turn_fraction(0.25);
// rotations should be equal
assert_relative_eq!(rotation1, rotation2);
// The rotation should be 90 degrees
assert_relative_eq!(rotation2.as_radians(), FRAC_PI_2);
assert_relative_eq!(rotation2.as_degrees(), 90.0);
```

# Objective
- Adds the missing API commands `insert_if_new_and` and
`try_insert_if_new_and` (resolves#15105)
- Adds some test coverage for existing insert commands
## Testing
- Implemented additional unit tests to add coverage
# Objective
Right now, `DynSystemParam::downcast()` always requires the type
parameter to be specified with a turbofish. Make it so that it can be
inferred from the use of the return value, like:
```rust
fn expects_res_a(mut param: DynSystemParam) {
let res: Res<A> = param.downcast().unwrap();
}
```
## Solution
The reason this doesn't currently work is that the type parameter is a
`'static` version of the `SystemParam` so that it can be used with
`Any::downcast_mut()`. Change the method signature so that the type
parameter matches the return type, and use `T::Item<'static, 'static>`
to get the `'static` version. That means we wind up returning a
`T::Item<'static, 'static>::Item<'w, 's>`, so constrain that to be equal
to `T`. That works with every `SystemParam` implementation, since they
have `T::Item == T` up to lifetimes.
# Objective
Fixes#14540
## Solution
- Clean slab layouts from stale `SlabId`s when freeing meshes
- Technically performance requirements of freeing now increase based on
the number of existing meshes, but maybe it doesn't matter too much in
practice
- This was the case before this PR too, but it's technically possible to
free and allocate 2^32 times and overflow with `SlabId`s and cause
incorrect behavior. It looks like new meshes would then override old
ones.
## Testing
- Tested in `loading_screen` example and tapping keyboard 1 and 2.
# Objective
- fix#12853
- Make `Table::allocate` faster
## Solution
The PR consists of multiple steps:
1) For the component data: create a new data-structure that's similar to
`BlobVec` but doesn't store `len` & `capacity` inside of it: "BlobArray"
(name suggestions welcome)
2) For the `Tick` data: create a new data-structure that's similar to
`ThinSlicePtr` but supports dynamic reallocation: "ThinArrayPtr" (name
suggestions welcome)
3) Create a new data-structure that's very similar to `Column` that
doesn't store `len` & `capacity` inside of it: "ThinColumn"
4) Adjust the `Table` implementation to use `ThinColumn` instead of
`Column`
The result is that only one set of `len` & `capacity` is stored in
`Table`, in `Table::entities`
### Notes Regarding Performance
Apart from shaving off some excess memory in `Table`, the changes have
also brought noteworthy performance improvements:
The previous implementation relied on `Vec::reserve` &
`BlobVec::reserve`, but that redundantly repeated the same if statement
(`capacity` == `len`). Now that check could be made at the `Table` level
because the capacity and length of all the columns are synchronized;
saving N branches per allocation. The result is a respectable
performance improvement per every `Table::reserve` (and subsequently
`Table::allocate`) call.
I'm hesitant to give exact numbers because I don't have a lot of
experience in profiling and benchmarking, but these are the results I
got so far:
*`add_remove_big/table` benchmark after the implementation:*
*`add_remove_big/table` benchmark in main branch (measured in comparison
to the implementation):*
*`add_remove_very_big/table` benchmark after the implementation:*
*`add_remove_very_big/table` benchmark in main branch (measured in
comparison to the implementation):*

## Changelog
- New data-structure that's similar to `BlobVec` but doesn't store `len`
& `capacity` inside of it: `BlobArray`
- New data-structure that's similar to `ThinSlicePtr` but supports
dynamic allocation:`ThinArrayPtr`
- New data-structure that's very similar to `Column` that doesn't store
`len` & `capacity` inside of it: `ThinColumn`
- Adjust the `Table` implementation to use `ThinColumn` instead of
`Column`
- New benchmark: `add_remove_very_big` to benchmark the performance of
spawning a lot of entities with a lot of components (15) each
## Migration Guide
`Table` now uses `ThinColumn` instead of `Column`. That means that
methods that previously returned `Column`, will now return `ThinColumn`
instead.
`ThinColumn` has a much more limited and low-level API, but you can
still achieve the same things in `ThinColumn` as you did in `Column`.
For example, instead of calling `Column::get_added_tick`, you'd call
`ThinColumn::get_added_ticks_slice` and index it to get the specific
added tick.
