+
+* [#10579] Make [quick-fixes](https://plugins.jetbrains.com/plugin/8182-rust/docs/rust-code-generation.html#intention-actions) work inside an attribute macro expansion.

If you want to try it out, enable `org.rust.macros.proc.attr` [experimental feature](https://plugins.jetbrains.com/plugin/8182-rust/docs/rust-faq.html#experimental-features).
