I just found How do I see the expanded macro code that's causing my compile error?. Is it possible to get the expansion of a single macro instead of the whole file?

3Wow from +6 to -3. @Shepmaster I think people weren't happy with your editing. Just joking ;) – bertfred Sep 08 '18 at 11:02

The cargo-expand command is really just a thin wrapper around cargo rustc -- -Zunstable-options --pretty=expanded, which is itself a blunt instrument. You can't target a specific macro.
However, since version 0.4, you can reduce some noise by specifying an extra path argument to expand only macros used by that module:
$ cargo expand path::to::module

"Show expanded macro" and "Show recursively expanded macro" commands were recently added to IntelliJ Rust.

It's a part of the plugin's logic, so I guess that you can't use it outside of IntelliJ-Rust. – ozkriff Oct 08 '18 at 14:56
