New Features

Inlay hints improvements:
- New inlay hints for chained method calls (by @Kobzol )
- Show type hints for type placeholders _ (by @avrong )
- Support blacklisting for inlay parameter hints. You can find these settings in Settings | Editor | Inlay Hints | Rust | Parameter hints | Blacklist... (by @Kobzol )
If you don’t like one of our new inlay hints, you can disable it in Settings | Editor | Inlay Hints | Rust .
Refactorings improvements:
- Provide Introduce Constant refactoring. You can invoke it via Refactor | Extract | Constant or Ctrl+Alt+C (by @Kobzol )
- Improve Extract Enum Variant refactoring. Now derive and repr attributes are copied from the parent enum to the generated struct (by @Kobzol )
- Also, Extract Enum Variant is now available from Refactor | Extract and Refactor | Refactor This menus (by @Kobzol )

Highlight errors in format string literal in macros like println , write , format , etc. (by @Kobzol )

Automatically insert missing <> when completing generic types (by @Kobzol )

Support include! macro calls generated by another macro call. Note, full support (name resolution and completion for code from including file in included one and correct module hierarchy recognition, i.e. absence of false positive “File is not included in module tree” editor notification), is available only when the new macro expansion engine is enabled (You can enable it in Settings | Languages & Frameworks | Rust | Expand Declarative macros ).

Show value of NonZero* numbers in the debugger (by @Kobzol )

Performance Improvements

Slightly optimized macro name resolution and expansion

Fixes UI freezes during project save if the new macro expansion engine is enabled

Improved macro expansion task cancellation. Typing in Cargo.toml should be smoother. This affects you only if the new macro expansion engine is enabled.

Fixes

Take into account extern keyword by Implement members quick fix (by @t-kameyama )

Fix false-positive E0603 module is private if the module is declared multiple times (e.g. in lib.rs and main.rs )
Go To Super action ( Ctrl+U ) now allows choosing a module declaration (if multiple)

Fix #[cfg()] attributes support. Ignore impl ’s from disabled submodules

Improve "complete current statement ( Ctrl+Shift+Enter ) action:
```
;
```

Implement Members and Generate Construct actions now take into account all trait bounds of trait object types

Omit unchanged default type parameters of parameters by Extract Function refactoring (by @Kobzol )

Fix Find Usages action:
```
include!()
pub(crate)
```

Fix the issue with non-rust directory renaming. Previously, the plugin sometimes broke “Rename” refactoring applied to a directory in non-rust projects.

Fix the issue with Surround with unsafe block quick fix (by @Kobzol )

Properly do Invalidate caches & Restart action

Fix Use of moved value false-positive error

Do not throw the exception while building a project via Build action

Fix IndexNotReadyException while completion during indexing

Fix possible java.lang.AssertionError exception during indexing

Fetch cargo metadata even with compilation error. Previously, if org.rust.cargo.evaluate.build.scripts experimental feature was enabled and there was compilation error, fetching cargo workspace data failed
