2834: refactor(ra_syntax.validation): removed code duplication from validate_literal() r=kiljacken a=Veetaha
Hi! This is my first ever contribution to this project.
I've taken some dirty job from issue #223
This is a simple atomic PR to remove code duplication according to FIXME comment in the function that is the main focus of the further development.
I just didn't want to mix refactoring with the implementation of new features...
I am not sure whether you prefer such atomic PRs here or you'd rather have a single PR that contains all atomic commits inside of it?
So if you want me to add all that validation in one PR I'll mark this one as WIP and update it when the work is finished, otherwise, I'll go with the option of creating separate PRs per each feature of validation of strings, numbers, and comments respectively.
### Comments about refactoring
Yeah, reducing the duplication is quite hard here, extracting into stateless functions could be another option but the number of their arguments would be very big and repeated across char and string implementations so that just writing their types and names would become cumbersome.
I tried the option of having everything captured implicitly in the closure but failed since rust doesn't have templated (or generic) closures as C++ does, this is needed because `unescape_byte*()` and `unescape_char|str()` have different return types...
Maybe I am missing something here? I may be wrong because I am not enough experienced in Rust...
Well, I am awaiting any kind of feedback!

2803: Fix various names, e.g. Iterator not resolving in core prelude r=matklad a=flodiebold
Basically, `Iterator` is re-exported via several steps, which happened to not be
resolved yet when we got to the prelude import, but since the name resolved to
the reexport from `core::iter` (just to no actual items), we gave up trying to
resolve it further.
Maybe part of the problem is that we can have
`PartialResolvedImport::Unresolved` or `PartialResolvedImport::Indeterminate`
with `None` in all namespaces, and handle them differently.
Fixes#2683.

2771: Remove the Default impl for SourceRoot r=matklad a=michalt
Let's be always explicit whether we create a library (i.e., an immutable
dependency) or a local `SourceRoot`, since it can have a large impact on
the validation performance in salsa. (we found it the hard way recently,
where the `Default` instance made it quite tricky to spot a bug)

When processing a change with added libraries, we used
`Default::default` for `SourceRoot` which sets `is_library` to false.
Since we use `is_library` to decide whether to use low or high
durability, I believe that this caused us to mark many library
dependencies as having low durability and thus increased the size of the
graph that salsa needed to verify on every change.
Based on my initial tests this speeds up the `CrateDefMapQuery` on
rust-analyzer from about ~64ms to ~14ms and reduces the number of
validations for the query from over 60k to about 7k.

2726: Improve profiling output when duration filter is specified r=matklad a=michalt
In particular:
- Use strict inequality for comparisons, since that's what the filter
syntax supports.
- Convert to millis for comparisons, since that's the unit used both
for the filter and when printing.
Now something like `RA_PROFILE='*>0'` will only print things that took
at least 1ms (when rounded to millis).

The `-` turned into a `+` during a refactoring.
The original issue was caused by `Read` resolving wrongly to a trait without
type parameters instead of a struct with one parameter; this only fixes the
crash, not the wrong resolution.
This change:
- introduces `compute_crate_def_map` query and renames
`CrateDefMap::crate_def_map_query` for consistency,
- annotates `crate_def_map` as `salsa::transparent` and adds a
top-level `crate_def_map` wrapper function around that starts the
profiler and immediately calls into `compute_crate_def_map` query.
This allows us to better understand where we spent the time, in
particular, how much is spent in the recomputaiton and how much in
salsa.
Example output (where we don't actually re-compute anything, but the
query still takes a non-trivial amount of time):
```
211ms - handle_inlay_hints
150ms - get_inlay_hints
150ms - SourceAnalyzer::new
65ms - def_with_body_from_child_node
65ms - analyze_container
65ms - analyze_container
65ms - Module::from_definition
65ms - Module::from_file
65ms - crate_def_map
1ms - parse_macro_query (6 calls)
0ms - raw_items_query (1 calls)
64ms - ???
```

2668: In-server cargo check watching r=matklad a=kiljacken
Opening a draft now so people can follow the progress, and comment if they spot something stupid.
Things that need doing:
- [x] Running cargo check on save
- [x] Pipe through configuration options from client
- [x] Tests for parsing behavior
- [x] Remove existing cargo watch support from VSCode extension
- [x] Progress notification in VSCode extension using LSP 3.15 `$/progress` notification
- [ ] ~~Rework ra-ide diagnostics to support secondary messages~~
- [ ] ~~Make cargo-check watcher use ra-ide diagnostics~~
~~I'd love some input on whether to try to keep the status bar progress thingy for VSCode? It will require some plumbing, and maintaining yet another rust-analyzer specific LSP notification, which I'm not sure we want to.~~

2667: Visibility r=matklad a=flodiebold
This adds the infrastructure for handling visibility (for fields and methods, not in name resolution) in the HIR and code model, and as a first application hides struct fields from completions if they're not visible from the current module. (We might want to relax this again later, but I think it's ok for now?)

2661: Implement infer await from async function r=flodiebold a=edwin0cheng
This PR is my attempt for trying to add support for infer `.await` expression from an `async` function, by desugaring its return type to `Impl Future<Output=RetType>`.
Note that I don't know it is supposed to desugaring it in that phase, if it is not suitable in current design, just feel free to reject it :)

2636: Chalk update and refactoring r=flodiebold a=flodiebold
This updates the Chalk integration to https://github.com/rust-lang/chalk/pull/311, which will presumably get merged soon, and refactors it some more, most notably introducing our own `TypeFamily` instead of reusing `ChalkIr`. It's still mostly the same as `ChalkIr` though, except for using Salsa `InternId`s directly.
Co-authored-by: Florian Diebold <flodiebold@gmail.com>
It's not very different, except we can directly use Salsa IDs instead of casting
them. This means we need to refactor the handling of errors to get rid of
UNKNOWN_TRAIT though.

1. Normal : `macro m { ($i:ident) => {} }` , which handle similar to legacy one.
2. Call like: `macro m($i:ident) {}`, it produces a single token tree which have two child token trees : `($i:ident)` and `{}`
