this is a small neovim plugin for utilizing rust-analyzer's recursively expand macro feature. just install it using your favorite plugin manager and use it like so:

require('rust-expand-macro').expand_macro()

this will expand whatever macro is currently under the cursor into a new buffer and will show it in a new vertical split.

yes, really. that's it. a single function - no need to call setup or anything like that.

rust-tools for being the reason why this plugins exists. i didn't want any of the features it offers except for recursive expansion of macros, so i made this plugin! also, the code here is heavily based on it's implementation.
