Rust

Rust is not currently offered as a core plugin. In fact, I don't think you should actually use mise for rust development. Rust has an official version manager called rustup that is better than what any of the current mise plugins offer.

You install rustup with the following:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

That said, rust is still one of the most popular languages to use in mise. A lot of users have success with it so if you'd like to keep all of your languages configured the same, don't feel like using mise is a bad idea either. Especially if you're only a casual rust user.

If you're a relatively heavy rust user making use of things like channel overrides, components, and cross-compiling, then I think you really should just be using rustup though. The experience will be better.

If one day we could figure out a way to provide an equivalent experience with mise, we could revisit this. We have discussed potentially using mise as a "front-end" to rustup where there is one rustup install that mise just manages so you could do something like this:

[tools]
rust = "nightly"

Where that would basically be equivalent to:

rustup override set nightly

Frankly though, this isn't high on my priority list. Use rustup. It's great.

Kudos for writing rust too btw, I've really enjoyed it so far—this is my first rust project.

Default crates

mise can automatically install a default set of creates right after installing a new rust version. To enable this feature, provide a $HOME/.default-cargo-crates file that lists one crate per line, for example:

cargo-edit
stylua
