minor: Allow multiple snippet edits in a `TextDocumentEdit`
Explicitly[^1] allow a single `TextDocumentEdit` to have multiple `SnippetTextEdit`s. This allows things like renaming extracted variables and functions without having to go through a separate rename step. For an example of what this looks like, see the video in [this comment](https://github.com/microsoft/vscode/issues/145374#issuecomment-1177341711).
The behavior described here lines up with [what VSCode does](bdc113ffe1/src/vscode-dts/vscode.d.ts (L3728-L3731)), and presumably what the eventual LSP behavior will be.
[^1]: This was technically the case before #15269, a single `TextDocumentEdit` always had multiple edits which were `InsertTextFormat.Snippet` as all of the edits were marked as being snippets, even if there weren't any tab stops or placeholders.
minor: Make "Expand macro" command title more explicit
Closes [#15856](https://github.com/rust-lang/rust-analyzer/issues/15856).
I opted for "caret", since it's the better term (cursor is the mouse), but I'm not sure how popular it is these days.
Due to the way the current tree mutation api works, we need to collect
changes before we can apply them to the real syntax tree, and also can only
switch to a file once.
`destructure_tuple_binding_in_sub_pattern` also gets migrated even
though can't be used.
Try to update parser/event doc
`TokenSource` and `TreeSink` has been refactored as part of #10765, they no longer exist in code repo. This pr tries to remove them from event module level comment to prevent confusion.
feat: add generate_mut_trait_impl assist
Generate proper `index_mut` method body refer to `index` method body may impossible due to the unpredicable case (#15581).
Here just leave the `index_mut` method body be same as `index` method body, user can modify it manually to meet their need.
fix: Fix docs path for derive macros
Fixes#15831.
Not sure about `attr`, I don't think those are documented anyway. And many macros don't work because we pick the wrong path.
They've been deprecated for four years.
This commit includes the following changes.
- It eliminates the `rustc_plugin_impl` crate.
- It changes the language used for lints in
`compiler/rustc_driver_impl/src/lib.rs` and
`compiler/rustc_lint/src/context.rs`. External lints are now called
"loaded" lints, rather than "plugins" to avoid confusion with the old
plugins. This only has a tiny effect on the output of `-W help`.
- E0457 and E0498 are no longer used.
- E0463 is narrowed, now only relating to unfound crates, not plugins.
- The `plugin` feature was moved from "active" to "removed".
- It removes the entire plugins chapter from the unstable book.
- It removes quite a few tests, mostly all of those in
`tests/ui-fulldeps/plugin/`.
Closes#29597.
