fix: self type replacement in inline-function
Fix#16113, fix#16091
The problem described in this issue actually involves three bugs.
Firstly, when using `ted` to modify the syntax tree, the offset of nodes on the tree changes, which causes the syntax range information from `hir` to become invalid. Therefore, we need to edit the AST after the last usage for `usages_for_locals`.
The second issue is that when inserting nodes, it's necessary to use `clone_subtree` for duplication because the `ted::replace` operation essentially moves a node.
The third issue is that we should use `ancestors_with_macros` instead of `ancestors` to handle impl definition in macros.
I have fixed the three bugs mentioned above and added unit tests.
internal: Migrate assists to the structured snippet API, part 5
Continuing from #15874
Migrates the following assists:
- `extract_variable`
- `generate_function`
- `replace_is_some_with_if_let_some`
- `replace_is_ok_with_if_let_ok`
Don't trim trailing whitespace from doc comments
Don't trim trailing whitespace from doc comments as multiple trailing spaces indicates a hard line break in Markdown.
I'd have liked to add a unit test for `docs_from_attrs`, but couldn't find a reasonable way to get an `&Attrs` object for use in the test.
Fixes#15877.
fix: make callable fields not complete in method access no parens case
Follow up PR for #15879
Fixes the callable field completion appearing in the method access with no parens case.
fix: no code action 'introduce_named_generic' for impl inside types
Fix#15734.
### Changes Made
- Find params in `ancestors` instead of just `parent`
- Added tests (`replace_impl_with_mut` and `replace_impl_inside`)
fix: Correct references from `rust-analyzer.cargo.check` to `rust-analyzer.check`
When reading the manual, I noticed that the documentation referenced configurations that have since been renamed. This PR updates those references to their new names.
fix: assists panic when trying to edit usage inside macro
When we try to make a syntax node mutable inside a macro to edit it, it seems like the edits aren't properly reflected and will cause a panic when trying to make another syntax node mutable.
This PR changes `bool_to_enum` and `promote_local_to_const` to use the original syntax range instead to edit the original file instead of the macro file. I'm not sure how to do it for `inline_call` with the example I mentioned in the issue, so I've left it out for now.
Fixes#15807
internal: Expose whether a channel has been dropped in lsp-server errors
Not the best way to expose this, but this should allow us to give somewhat better errors when the initialization request is malformed, as currently that just results in a channel disconnected error instead of the deserialization error. cc https://github.com/rust-lang/rust-analyzer/issues/15859
fix: Fix out-of-bounds panic in some macros due to unhandled self_ref
Fixes#16200
I don't fully understand these changes, I just applied and tested the changes suggested in #16200 and they seem to fix the issue on both the repro and my original project.
internal: Simplify implementation of apply_document_changes
While reading through the code base, I stumbled across a piece of code that I found hard to read despite its simple purpose. This is my attempt at making the code easier to understand for future readers.
I won't be offended if this is too minor and not worth your time.

fix: update VSCode rust-panic problem matcher
Corrected the `rust-panic` task problem matcher for the VSCode Extension to match the new panic message pattern.
From:
```
thread 'main' panicked at 'PANIC_MESSAGE', src/main.rs:L:C
```
To:
```
thread 'main' panicked at src/main.rs:L:C:
PANIC_MESSAGE
```
add test case for negative impl
add a small test case to ensure that we don't emit `trait_impl_redundant_assoc_item` diagnostic for negative impl trait
internal: Update world symbols request definiton, prefer focus range for macros
Prior to this, the symbol search would always jump to the defining macro call, not it jumps to the name in the macro call input if possible. This is a large improvement for assoc items in an attribute impl or trait.
Complete exported macros in `#[macro_use($0)]`
Closes https://github.com/rust-lang/rust-analyzer/issues/15657.
Originally added a test case for incomplete input:
```rust
#[test]
fn completes_incomplete_syntax() {
check(
r#"
//- /dep.rs crate:dep
#[macro_export]
macro_rules! foo {
() => {};
}
//- /main.rs crate:main deps:dep
#[macro_use($0
extern crate dep;
"#,
expect![[r#"
ma foo
"#]],
)
}
```
but couldn't make it pass and removed it 😅 Our current recovering logic doesn't work for token trees and for this code:
```rust
#[macro_use(
extern crate lazy_static;
fn main() {}
```
we ended up with this syntax tree:
```
SOURCE_FILE@0..53
ATTR@0..52
POUND@0..1 "#"
L_BRACK@1..2 "["
META@2..52
PATH@2..11
PATH_SEGMENT@2..11
NAME_REF@2..11
IDENT@2..11 "macro_use"
TOKEN_TREE@11..52
L_PAREN@11..12 "("
WHITESPACE@12..13 "\n"
EXTERN_KW@13..19 "extern"
WHITESPACE@19..20 " "
CRATE_KW@20..25 "crate"
WHITESPACE@25..26 " "
IDENT@26..37 "lazy_static"
SEMICOLON@37..38 ";"
WHITESPACE@38..40 "\n\n"
FN_KW@40..42 "fn"
WHITESPACE@42..43 " "
IDENT@43..47 "main"
TOKEN_TREE@47..49
L_PAREN@47..48 "("
R_PAREN@48..49 ")"
WHITESPACE@49..50 " "
TOKEN_TREE@50..52
L_CURLY@50..51 "{"
R_CURLY@51..52 "}"
WHITESPACE@52..53 "\n"
```
Maybe we can try to parse the token tree in `crates/ide-completion/src/context/analysis.rs` but I'm not sure what's the best way forward.
feat: Implement a rust-analyzer span backed proc-macro server mode
This implements the basic span APIs. Basically anything that doesn't require talking back to the client for information access.
This also commits our syntax fixup marker to use an `ErasedAstFileId` of `!0-1` aka `0xffff_fffe`, instead of using a dummy FileId as a marker, as we need that for the `SourceFile` API to be implementable. The reason as to why the server needs to know about this at all is to prevent it from creating invalid fixup spans which could make r-a panic.
