# install-rust
A small github action to install `rustup` and a Rust toolchain. This is
generally expressed inline, but it was repeated enough in this repository it
seemed worthwhile to extract.
Some gotchas:
* Can't `--self-update` on Windows due to permission errors (a bug in Github
Actions)
* `rustup` isn't installed on macOS (a bug in Github Actions)
When the above are fixed we should delete this action and just use this inline:
```yml
- run: rustup update $toolchain && rustup default $toolchain
shell: bash
```
