A concise GitHub Action that installs a Rust toolchain via rustup with one-line usage and sensible defaults. The toolchain version is selected by the action's @rev (e.g. @stable, @nightly, @1.89.0), with optional inputs for additional targets and components like clippy and rustfmt.

Use cases

• install rust toolchain in a github actions workflow
• set up rust ci to run cargo test on push and pull requests
• install nightly rust compiler in ci
• pin a specific rust version like 1.89.0 for builds
• add clippy and rustfmt components in ci
• install wasm32 target for cross-compilation in ci
• get a cache key based on the installed rustc version

When to choose

• You use GitHub Actions and want minimal, one-line Rust setup
• You need to test against stable, nightly, dated nightly, or pinned Rust versions
• You want extra targets (e.g. wasm32) or components (clippy, rustfmt) installed in the same step
• You need a compiler-version-derived cache key or toolchain name as step outputs

When to avoid

• Your CI runs outside GitHub Actions, such as GitLab CI or CircleCI
• You need to manage rustup toolchains on a local development machine rather than in CI
• You require complex multi-toolchain orchestration beyond what a single install step provides
