Setup Rust (Forgejo)

Forgejo's dtolnay/rust-toolchain. Install a Rust toolchain with rustup on a self-hosted Forgejo runner: channel or pinned version, components, targets, profile. rustup comes from sh.rustup.rs and toolchains from static.rust-lang.org, so nothing here depends on github.com or a PAT.

Part of the Fjord Actions bundle. Pairs with rust-cache-action for the cargo cache.

Usage

jobs:
  build:
    runs-on: [self-hosted, Linux]
    steps:
      - uses: actions/checkout@v6

      - uses: https://rasterhub.com/fjord/setup-rust-action@v1
        with:
          toolchain: stable
          components: rustfmt, clippy

      - uses: https://rasterhub.com/fjord/rust-cache-action@v1
      - run: cargo test --all --locked

Inputs

Input	Default	Description
toolchain	stable	Channel (stable/beta/nightly), version (1.79.0), or dated nightly (nightly-2026-01-01).
targets		Cross-compile targets to add, comma or space separated.
components		Extra components (e.g. rustfmt, clippy), comma or space separated.
profile	minimal	rustup profile: minimal / default / complete.
override	true	Set the installed toolchain as the default (rustup default).

Outputs

Output	Description
version	The installed rustc version string.
cachekey	Short hash of rustc -vV, handy as a cache-key segment.

Notes

• If rustup is already on the runner it's used as-is; otherwise it's installed non-interactively with the chosen profile. ~/.cargo/bin is added to GITHUB_PATH for later steps.
• This action does not cache anything. Use rust-cache-action for the cargo registry/target cache; pass cachekey into your own cache key if you cache manually.
