rust-analyzer support

However if I type which cargo directly, it can be found:

% which cargo
/Users/alanxu/.cargo/bin/cargo

Here is my settings.json automatically generated by mise-vscode extension:

Thanks for the report. Please note that currently, mise-vscode does not try to configure any settings regarding the rust-analyzer extension. (list of currently supported extensions)

I have managed to reproduce your issue. This happens if you have installed rust (e.g., with mise) but did not add the cargo bin to PATH.

Unfortunately, there is no way to cleanly override the path to cargo for rust-analyzer (see rust-lang/rust-analyzer#16204). I think I can't do much apart from documenting a workaround.

Workarounds

Add shims to PATH

Follow the recommended approach here: https://mise.jdx.dev/ide-integration.html#adding-shims-to-path-default-shell

For example, if you use bash, you can add the following to your ~/.profile.

eval "$(mise activate bash --shims)"

Add cargo bin to path

You can also update your shell rc file with:

export PATH="$HOME/.cargo/bin:$PATH"

then re-launch VSCode

The Add cargo bin to path workaround works! I'm not sure what's the difference between mise activate bash --shims and mise activate bash? The former only adds a path to the $PATH variable, but the later outputs a lot of functions.
