# Install Rust Toolchain
This GitHub Action installs a Rust toolchain using rustup. It is designed for
one-line concise usage.
## Example workflow
```yaml
name: test suite
on: [push, pull_request]
jobs:
test:
name: cargo test
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- uses: dtolnay/rust-toolchain@stable
- run: cargo test --all-features
```
The selection of Rust toolchain is made based on the particular @rev of this
Action being requested. For example "dtolnay/rust-toolchain@nightly" pulls in
the nightly Rust toolchain, while "dtolnay/rust-toolchain@1.42.0" pulls in
1.42.0.
## Inputs
All inputs are optional.
| Name | Description |
| ------------ | -----------------------------------------------------------------------------------------------------------------------------------|
| `toolchain` | Rustup toolchain specifier, ex. `stable`, `nightly`, `1.42.0`. **Important: the default is to match the @rev as described above.** |
