The rule `display: inline-block` was added in
5afa52bc7dee683f25f437dddf338dbc6ad32eb8.
The `margin: 0` and `font-weight: normal` were added in
c01bd560e2f87a9a960ed071213edd70f73171a8.
Both seem to have been added to override class-based rules that were
targetted at method sections. See
<c01bd560e2/src/librustdoc/html/static/rustdoc.css (L140-L148)>
for an example. The selectors that these were meant to override were changed
in a8318e420d19c364b1eec33956a86164941f6df4 and
76a3b609d0b93c5d8da5e4e3db37bd03e5cb1c30 to be more specific, so they no
longer need to be overridden.
Feature gate the `rustdoc::missing_doc_code_examples` lint
Moves the lint from being implicitly active on nightly `rustdoc` to requiring a feature to activate, like other unstable lints.
Uses the new tracking issue https://github.com/rust-lang/rust/issues/101730
rustdoc: improve rustdoc HTML suggestions handling of nested generics
Based on some poor suggestions produced when stablizing this lint and running it on `manformed-generics.rs` in #101720
Don't panic on invalid shift while constfolding
Instead of panicking on invalid shifts while folding constants we simply give up. Fixes#9463
Notice the "attempt to shift right by `1316134912_u32`", which seems weird. AFAICS it comes from rustc itself.
changelog: none
Don't lint `large_stack_array` inside static items
We now check if the linted `Expr` is inside an `ItemKind::Static`, which can't take the suggested `Box<[...]`. I _think_ this is the correct fix for #9460
I removed `if_chain` while I was at it.

fix: handle lifetime variables in projection normalization
Fixes#12674
The problem is that we've been skipping the binders of normalized projections assuming they should be empty, but the assumption is unfortunately wrong. We may get back lifetime variables and should handle them before returning them as normalized projections. For those who are curious why we get those even though we treat all lifetimes as 'static, [this comment in chalk](d875af0ff1/chalk-solve/src/infer/unify.rs (L888-L908)) may be interesting.
I thought using `InferenceTable` would be cleaner than the other ways as it already has the methods for canonicalization, normalizing projection, and resolving variables, so moved goal building and trait solving logic to a new `HirDatabase` query. I made it transparent query as the query itself doesn't do much work but the eventual call to `HirDatabase::trait_solve_query()` does.
Primitive doesn't include Array/Slice/Tuple, as they are their own
variants.
ResolvedPath doesn't include Traits, as they appear in the DynTrait
variant.
Remove the toggleInlayHints command from VSCode
Inlay hints are no longer something specifc to r-a as it has been upstreamed into the LSP, we don't have a reason to give the config for this feature special treatment in regards to toggling. There are plenty of other options out there in the VSCode marketplace to create toggle commands/hotkeys for configurations in general which I believe we should nudge people towards instead.
fix: handle trait methods as inherent methods for trait-related types
Fixes#10677
When resolving methods for trait object types and placeholder types that are bounded by traits, we need to count the methods of the trait and its super traits as inherent methods. This matters because these trait methods have higher priority than the other traits' methods.
Relevant code in rustc: [`assemble_inherent_candidates_from_object()`](0631ea5d73/compiler/rustc_typeck/src/check/method/probe.rs (L783-L792)) for trait object types, [`assemble_inherent_candidates_from_param()`](0631ea5d73/compiler/rustc_typeck/src/check/method/probe.rs (L838-L847)) for placeholder types. Notice the second arg of `push_candidate()` is `is_inherent`.
Remove redundant 'resolve_obligations_as_possible' call
Hi! I was looking for a "good first issue" and saw this one: https://github.com/rust-lang/rust-analyzer/issues/7542. I like searching for performance improvements, so I wanted to try to find something useful there.
There are two tests in integrated_benchmarks.rs, I looked at 'integrated_highlighting_benchmark' (not the one discussed in the issue above).
Profile from that test looks like this:
```

```
22106 calls to `resolve_obligations_as_possible` seem like the main issue there.
One thing I noticed (and fixed in this PR) is that `InferenceContext::resolve_ty_shallow` first calls `resolve_obligations_as_possible`, and then calls `InferenceTable::resolve_ty_shallow`. But `InferenceTable::resolve_ty_shallow` [inside](2e9f1204ca/crates/hir-ty/src/infer/unify.rs (L372)) again calls `resolve_obligations_as_possible`.
`resolve_obligations_as_possible` inside has a while loop, which works until it can't find any helpful information. So calling this function for the second time does nothing, so one of the calls could be safely removed.
`InferenceContext::resolve_ty_shallow` is actually quite a hot place, and after fixing it, the total number of `resolve_obligations_as_possible` in this test is reduced to 15516 (from 22106). "After change" time also improves from ~270ms to ~240ms, which is not a very huge win, but still something measurable.
Same profile after PR:

```
The performance of this test could be further improved but at the cost of making code more complicated, so I wanted to check if such a change is desirable before sending another PR.
`resolve_obligations_as_possible` is actually called a lot of times even when no new information was provided. As I understand, `resolve_obligations_as_possible` could do something useful only if some variables/values were unified since the last check. We can store a boolean variable inside `InferenceTable`, which indicates if `try_unify` was called after last `resolve_obligations_as_possible`. If it wasn't called, we can safely not call `resolve_obligations_as_possible` again.
I tested this change locally, and it reduces the number of `resolve_obligations_as_possible` to several thousand (it is not shown in the profile anymore, so don't know the exact number), and the total time is reduced to ~180ms. Here is a generated profile:

Let me know if adding a new bool field seems like a reasonable tradeoff, so I can send a PR.
rustdoc: remove no-op `#search`
The margin rule was added in c729e4dca7581fcd060978bcb0d7f98ea4eb6b82 to remove an unnecessary left margin that was present on desktop. This desktop-mode margin was itself removed in 135281ed1525db15edd8ebd092aa10aa40df2386.
The padding rule was added in 135281ed1525db15edd8ebd092aa10aa40df2386 when converting the rule for `#main`, but didn't do anything even then.
