Install Rust Toolchain

This GitHub Action installs a Rust toolchain using rustup. It is designed for one-line concise usage and good defaults.


Example workflow

name: test suite
on: [push, pull_request]

jobs:
  test:
    name: cargo test
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - 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 e.g. stable, nightly, 1.42.0, nightly-2022-01-01. Important: the default is to match the @rev as described above. When passing an explicit toolchain as an input instead of @rev, you'll want to use "dtolnay/rust-toolchain@master" as the revision of the action.
targets Comma-separated string of additional targets to install e.g. wasm32-unknown-unknown
components Comma-separated string of additional components to install e.g. clippy, rustfmt

Outputs

Name Description
cachekey A short hash of the installed rustc version, appropriate for use as a cache key. "20220627a831"
name Rustup's name for the selected version of the toolchain, like "1.62.0". Suitable for use with cargo +${{steps.toolchain.outputs.name}}.

Toolchain expressions

     # Installs the most recent stable toolchain as of the specified time
     # offset, which may be written in years, months, weeks, or days.
  - uses: dtolnay/rust-toolchain@master
    with:
      toolchain: stable 18 months ago
     # Installs the stable toolchain which preceded the most recent one by
     # the specified number of minor versions.
  - uses: dtolnay/rust-toolchain@master
    with:
      toolchain: stable minus 8 releases
