cargo_expand.nvim

Display a selector of compilation targets from your root directory. Run cargo-expand on the selected option. Dump the results into a scratch buffer and flick on syntax highlights for said buffer.

To be clear, this plugin can be replicated by typing this into your terminal

cargo expand --lib yourlib > .expanded.rs
nvim .expanded.rs

The plugin just has the added benefit(?) of showing a vim.ui.select of the parsed cargo metadata.

Setup

• Lazy

{
    "chrisp60/cargo_expand.nvim",
    config = function()
        vim.keymap.set("n", "[your keybind]", require("cargo_expand").expand)
    end,
}

TODO

• Configuration options.
• Any and all documentation, vim help docs.
• Display compilation progress in scratch buffer.
• support for rustc --emit={llvm-ir, asm, mir, etc..}.
  • I personally have been trying to write more unsafe code, it is nice to see how things get represented in assembly and intermediate representations.
