At the moment, this moves only a single diagnostic, but the idea is
reafactor the rest to use the same pattern. We are going to have a
single file per diagnostic. This file will define diagnostics code,
rendering range and fixes, if any. It'll also have all of the tests.
This is similar to how we deal with assists.
After we refactor all diagnostics to follow this pattern, we'll probably
move them to a new `ide_diagnostics` crate.
Not that we intentionally want to test all diagnostics on this layer,
despite the fact that they are generally emitted in the guts on the
compiler. Diagnostics care to much about the end presentation
details/fixes to be worth-while "unit" testing. So, we'll unit-test only
the primary output of compilation process (types and name res tables),
and will use integrated UI tests for diagnostics.
9169: internal: steps towards attribute macro token mapping r=jonas-schievink a=jonas-schievink
This doesn't work yet, but we seem to be getting a bit further along (for example, we now stop highlighting `use` items inside item with attribute macros as if they were written verbatim).

e.g. if you have a trait T and `impl T for S` for some struct, if you
goto definition on some function name inside the impl, it will go to the
definition of that function inside the `trait T` block, rather than the
current behaviour of not going anywhere at all.
9130: Prefix/suffix parameter inlay hint hiding heuristic is more strict r=Veykril a=Veykril
Instead of just plainly checking prefix/suffix of the argument string to the parameter name we only check for prefixes and suffixes if they are split apart via an underscore meaning, with the argument `foo`, it will be hidden for the parameter name `foo_bar` but not for `foobar`.

8997: internal: stop expanding UseTrees during ItemTree lowering r=jonas-schievink a=jonas-schievink
Closes https://github.com/rust-analyzer/rust-analyzer/issues/8908
Messy diff, but `ItemTree` lowering got simpler, since we now have a strict 1-to-1 mapping between `ast::Item` and `ModItem`.
The most messy part is mapping a single `UseTree` back to its `ast::UseTree` counterpart for diagnostics, but I think the ad-hoc source map built during lowering does the job.

9002: Move annotations below item attributes r=Veykril a=Veykril
This moves annotations/code lenses below attributes in items, bringing them inline with functions where this is already the case. This is done by changing the annotations covering range to just the name node's range which is also more inline with what the lsp expects which is that the range should ideally only cover a single line.

8996: Fix bug where library functions were not highlighted as such r=arzg a=arzg
Sorry about forgetting to test this in my last PR.
Co-authored-by: Aramis Razzaghipour <aramisnoah@gmail.com>
The idea here is to eventually get rid of `dyn Diagnostic` and
`DiagnosticSink` infrastructure altogether, and just have a `enum
hir::Diagnostic` instead.
The problem with `dyn Diagnostic` is that it is defined in the lowest
level of the stack (hir_expand), but is used by the highest level (ide).
As a first step, we free hir_expand and hir_def from `dyn Diagnostic`
and kick the can up to `hir_ty`, as an intermediate state. The plan is
then to move DiagnosticSink similarly to the hir crate, and, as final
third step, remove its usage from the ide.
One currently unsolved problem is testing. You can notice that the test
which checks precise diagnostic ranges, unresolved_import_in_use_tree,
was moved to the ide layer. Logically, only IDE should have the infra to
render a specific range.
At the same time, the range is determined with the data produced in
hir_def and hir crates, so this layering is rather unfortunate. Working
on hir_def shouldn't require compiling `ide` for testing.
I forgot to put this into #8988, sorry.
Goto implementation on a const on the trait will go to the
implementations with their respective definitions of the const, if
present.
Example:
```rust
struct A;
struct B {
a/*<- cursor*/: A,
}
```
Go to type definition used to not work on this position. It now goes to
`A` as expected.
8942: Add `library` semantic token modifier to items from other crates r=arzg a=arzg
Closes#5772.
A lot of code here is pretty repetitive; please let me know if you have any ideas how to improve it, or whether it’s fine as-is.
Side-note: How can I add tests for this? I don’t see a way for the test Rust code in `test_highlighting` to reference other crates to observe the new behaviour.

8813: Get some more array lengths! r=lf- a=lf-
This is built on #8799 and thus contains its changes. I'll rebase it onto master when that one gets merged. It adds support for r-a understanding the length of:
* `let a: [u8; 2] = ...`
* `let a = b"aaa"`
* `let a = [0u8; 4]`
I have added support for getting the values of byte strings, which was not previously there. I am least confident in the correctness of this part and it probably needs some more tests, as we currently have only one test that exercised that part (!).
Fixes#2922.

8799: Add basic support for array lengths in types r=flodiebold a=lf-
This recognizes `let a = [1u8, 2, 3]` as having type `[u8; 3]` instead
of the previous `[u8; _]`. Byte strings and `[0u8; 2]` kinds of range
array declarations are unsupported as before.
I don't know why a bunch of our rustc tests had single quotes inside
strings un-escaped by `UPDATE_EXPECT=1 cargo t`, but I don't think it's
bad? Maybe something in a nightly?

Attempting to rename an element of a tuple field would previously
replace the type with the new name, which doesn't make sense; now it
fails instead.
The check is done in both `prepare_rename` and `rename` so that the case
is caught before the user is prompted for a new name. Some other
existing failure cases are also now additionally checked in
`prepare_rename`.
8540: Prevent being able to rename items that are not part of the workspace r=Veykril a=Veykril
This change causes renames that happen on items coming from crates outside the workspace to fail. I believe this should be the right approach, but usage of cargo's workspace might not be entirely correct for preventing these kinds of refactoring from touching things they shouldn't. I'm not entirely sure?
cc #6623, this is one of the bigger footguns when it comes to refactoring, especially in combination with import aliases people tend to rename items coming from a crates dependency which this prevents.

8267: Adding gifs and screenshots for features in manual r=matklad a=MozarellaMan
For #6539
This includes most of gif or screenshot examples of most items in the "Features" header. With the exceptions of:
- **On Typing Assists** - couldn't get it to work for a demo, I'm probably missing something?
- **Structural search and replace** - looked to be already a visual example of the feature
- **Workspace symbol** - wasn't sure how best to show this, all of the examples maybe? Also wasn't sure of the best code example to show it off
- **Semantic Syntax Highlighting** - seemed obvious enough to not need a screenshot, but I could easily add this
All the gifs/pngs are hosted in this [comment](https://github.com/rust-analyzer/rust-analyzer/issues/6539#issuecomment-809574840). Please let me know if any of them aren't suitable (and why) and I'll improve it! Or if you don't like the theme/font

7900: show function params in completion detail r=matklad a=JoshMcguigan
This resolves#7842 by updating the detail for function completions from `-> T` to `fn(T, U) -> V`. I added an expicit unit test for this, `ide_completion::render::fn_detail_includes_args_and_return_type`, which passes.
Lots of other unit tests fail (~60 of them) due to this change, although I believe the failures are purely cosmetic (they were testing the exact format of this output). I'm happy to go update those tests, but before I do that I'd like to make sure this is in fact the format we want for the detail?
edit - I realized `UPDATE_EXPECT=1 cargo test` automatically updates `expect!` tests. Big 👍 to whoever worked on that! So I'll go ahead and update all these tests soon. But I still would like to confirm `fn(T, U) -> V` is the desired content in the `detail` field.

What happens here is that we lower `: ` to a missing expression, and
then correctly record that the corresponding field expression resolves
to a specific field. Where we fail is in the mapping of syntax to this
missing expression. Doing it via `ast_field.expr()` fails, as that
expression is `None`. Instead, we go in the opposite direcition and ask
each lowered field about its source.
This works, but has wrong complexity `O(N)` and, really, the
implementation is just too complex. We need some better management of
data here.
