# `rustup toolchain` Action
|
|
|
|
This GitHub Action installs [Rust toolchain](https://github.com/rust-lang/rustup.rs#toolchain-specification).
|
|
|
|
Optionally it can set installed toolchain as a default and as an override for current directory.
|
|
|
|
## Example workflow
|
|
|
|
```yaml
|
|
on: [push]
|
|
|
|
name: build
|
|
|
|
jobs:
|
|
check:
|
|
name: Rust project
|
|
runs-on: ubuntu-latest
|
|
steps:
|
|
- uses: actions/checkout@master
|
|
- name: Install nightly
|
|
uses: actions-rs/toolchain@1
|
|
with:
|
|
toolchain: nightly
|
|
override: true
|
|
```
|
|
|
|
## Inputs
|
|
|
|
* `toolchain` (*required*): Toolchain name, see [rustup page](https://github.com/rust-lang/rustup.rs#toolchain-specification) for details.\
|
|
Examples: `stable`, `nightly`, `nightly-2019-04-20`
|
|
* `target`: Additionally install specific target for this toolchain (ex. `x86_64-apple-darwin`)
|
|
* `default`: Set installed toolchain as default (executes `rustup toolchain default {TOOLCHAIN}`)
|
|
* `override`: Set installed toolchain as an override for current directory
|
|
|
|
## Notes
|
|
|
|
As `rustup` is not installed by default for macOS and Windows images at the moment (2019-09-13),
|
|
this Action will try its best to install it before any other operations.
