internal: Improve inlay hint resolution reliability
The payload now ships the range the inlay hint ought to be triggered for instead of trying to estimate it from its position which is somewhat brittle
Do not report missing unsafe on `addr_of[_mut]!(EXTERN_OR_MUT_STATIC)`
The compiler no longer does as well; see https://github.com/rust-lang/rust/pull/125834.
Also require unsafe when accessing `extern` `static` (other than by `addr_of!()`).
Fixes#17978.
fix: `std::error::Error` is object unsafe
Fixes#17998
I tried to get generic predicates of assoc function itself, not inherited from the parent here;
0ae42bd425/crates/hir-ty/src/object_safety.rs (L420-L442)
But this naive equality check approach doesn't work when the assoc function has one or more generic paramters like;
```rust
trait Foo {}
trait Bar: Foo {
fn bar(&self);
}
```
because the generic predicates of the parent, `Bar` is `[^1.0 implements Foo]` and the generic predicates of `fn bar` is `[^1.1 implements Foo]`, which are different.
This PR implements a correct logic for filtering out parent generic predicates for this.
fix: consider indentation in the "Generate impl" and "Generate trait impl" assists
This makes the generated impl's indentation match the ADT it targets, improving formatting when using nested modules inside of the same file or when defining types inside of a function. See the added tests for an example.
At first I tried to call some of the convenient helpers that delegate to `IndentLevel::increase_indent` on the generated impl, but as the comment on that function notes it does not indent the first token, making it inapplicable here. I hope the solution in this PR is acceptable, please let me know if I missed something :)

fix: do not assume rustup is installed in xtask codegen
When formatting generated code the xtask crate attempts to run `rustup run stable rustfmt`, which fails if `rustup` is not installed. This results in test failures when another source manages the compiler toolchain, for example when using Nix (or any other distro-specific packaging solution):
* xtask::codegen::grammar::test
* xtask::codegen::assists_doc_tests::test
With this PR xtask will first attempt to run `rustup run stable rustfmt`, and if that fails just plain `rustfmt`. It still validates a stable version is being used. This allows `cargo test` to pass on systems that do not use `rustup`.
Consider field attributes when converting from tuple to named struct and the opposite
Fixes#17983.
I tried to use the `SourceChangeBuilder::make_mut()` API, but it duplicated the attribute...
fix: Don't add reference when it isn't needed for the "Extract variable" assist
I.e. don't generate `let var_name = &foo()`. Because it always irritates me when I need to fix that.
Anything that creates a new value don't need a reference. That excludes mostly field accesses and indexing.
I had a thought that we can also not generate a reference for fields and indexing as long as the type is `Copy`, but sometimes people impl `Copy` even when they don't want to copy the values (e.g. a large type), so I didn't do that.
Fix incorrect symbol definitions in SCIP output
The SCIP output incorrectly marks some symbols as definitions because it doesn't account for the file ID when comparing the token's range to its definition's range.
This means that if a symbol is referenced in a file at the same position at which it is defined in another file, that reference will be marked as a definition. I was quite surprised by how common this is. For example, `PartialEq` is defined [here](https://github.com/rust-lang/rust/blob/1.80.1/library/core/src/cmp.rs#L273) and `uuid` references it [here](https://github.com/uuid-rs/uuid/blob/1.8.0/src/lib.rs#L329). And what do you know, they're both at offset 10083! In our large monorepo, this happens for basically every common stdlib type!
feat: Create an assist to convert closure to freestanding fn
The assist converts all captures to parameters.
Closes#17920.
This was more work than I though, since it has to handle a bunch of edge cases...
Based on #17941. Needs to merge it first.
internal: Avoid newlines in fetch errors
Most logs lines don't have newlines, ensure fetch errors follow this pattern. This makes it easier to see which log line is associated with the error.
Before:
2024-08-28T21:11:58.431856Z ERROR FetchWorkspaceError:
rust-analyzer failed to discover workspace
After:
2024-08-28T21:11:58.431856Z ERROR FetchWorkspaceError: rust-analyzer failed to discover workspace
I.e. don't generate `let var_name = &foo()`.
