Install Rust Toolchain

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

Example workflow

name: test suite
on: [push, pull_request]

jobs:
  test:
    name: cargo test
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - 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.
target	Additional target support to install e.g. wasm32-unknown-unknown
components	Comma-separated string of additional components to install e.g. clippy, rustfmt
