## Message

```
Add an action to expand Rust macros with rust-analyzer  (#3580)

Deals with https://github.com/zed-industries/community/issues/1282

If rust-analyzer responds with non-empty message, opens a new singleton
multibuffer with the expansion result:

In gpui2, only editors with excerpts containing Rust languages get the
action, in gpui1 every editor (even the *.ts one) has this action
enabled but it does nothing.

Release Notes:

- Added an `editor::ExpandMacroRecursively` command to expand Rust
macros with rust-analyzer.
```
