We generally avoid "syntax only" helper wrappers, which don't do much:
they make code easier to write, but harder to read. They also make
investigations harder, as "find_usages" needs to be invoked both for the
wrapped and unwrapped APIs
9814: Generate default impl when converting `#[derive(Debug)]` to manual impl r=yoshuawuyts a=yoshuawuyts
This patch makes it so when you convert `#[derive(Debug)]` to a manual impl, a default body is provided that's equivalent to the original output of `#[derive(Debug)]`. This should make it drastically easier to write custom `Debug` impls, especially when all you want to do is quickly omit a single field which is `!Debug`.
This is implemented for enums, record structs, tuple structs, empty structs - and it sets us up to implement variations on this in the future for other traits (like `PartialEq` and `Hash`).
Thanks!
## Codegen diff
This is the difference in codegen for record structs with this patch:
```diff
struct Foo {
bar: String,
}
impl fmt::Debug for Foo {
fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result {
- todo!();
+ f.debug_struct("Foo").field("bar", &self.bar).finish()
}
}
```

9808: fix: Look for enum variants and trait assoc functions when looking for lang items r=matklad a=Veykril
Examples for lang enum variants are the `Option` variants.
Assoc trait functions aren't being seen since they aren't declared in the direct module scope.

9785: feature: Add completion for struct literals in which all fields are visible. r=Veykril a=Afourcat
This PR adds a new completion for struct literal.
It Implements the feature discussed in the issue #9610.
This PR introduce a repetition in the source files `crates/ide_completion/render/pattern.rs` and `crates/ide_completion/render/struct_literal.rs` that may be fix in another PR.

Fix ide_completion tests.
Move 'complete_record_literal' call to the main completion function.
Fix a rendering bug when snippet not available.
Checks if an expression is expected before adding completion for struct literal.
Move 'completion struct literal with private field' test to 'expressions.rs' test file.
Update 'expect' tests with new check in 'complete record literal'.
9734: semantic highlighting: add reference hlmod r=matklad a=jhgg
This PR adds the "reference" highlight modifier!
I basically went around and looked for `HlMod::Mutable` to find the callsites to add a reference. I think these all make sense!
