pre-commit-hooks

Rust-based hooks for pre-commit and pre-commit.ci.

Hooks

cargo-fmt-nightly

Runs cargo fmt with RUSTUP_TOOLCHAIN=nightly.

Example:

- repo: https://github.com/arista-netdevops-community/pre-commit-hooks
  rev: <rev>
  hooks:
    - id: cargo-fmt-nightly
      args:
        - --all
        - --
        - --config
        - unstable_features=true,group_imports=StdExternalCrate,imports_granularity=Item

cargo-fmt

Runs cargo fmt with the target repository's selected Rust toolchain.

Example:

- repo: https://github.com/arista-netdevops-community/pre-commit-hooks
  rev: <rev>
  hooks:
    - id: cargo-fmt
      args: ["--all"]

cargo-check

Runs cargo check with the target repository's selected Rust toolchain.

Example:

- repo: https://github.com/arista-netdevops-community/pre-commit-hooks
  rev: <rev>
  hooks:
    - id: cargo-check
      args: ["--locked"]

cargo-clippy

Runs cargo clippy with the target repository's selected Rust toolchain.

Example:

- repo: https://github.com/arista-netdevops-community/pre-commit-hooks
  rev: <rev>
  hooks:
    - id: cargo-clippy
      args: ["--locked", "--all-targets", "--all-features"]

cargo-deny

Runs cargo-deny directly. The hook installs and invokes the version pinned as a Cargo CLI dependency in pre-commit's isolated environment.

Example:

- repo: https://github.com/arista-netdevops-community/pre-commit-hooks
  rev: <rev>
  hooks:
    - id: cargo-deny
      args: ["--locked", "--all-features", "check"]

cargo-about

Generates licenses with the cargo-about library linked into cargo-about-hook. The dependency version is maintained in Cargo.toml; no separate cargo-about executable or Cargo CLI installation features are needed. Installing the Rust hooks requires Rust 1.88 or newer.

The adapter supports only generate, with --locked, --manifest-path, -o/--output-file, and a single Handlebars template file. It discovers about.toml beside the manifest or in a parent directory, using cargo-about's configuration, workarounds, and license-resolution behavior. Output defaults to stdout; -o - also writes to stdout.

Example:

- repo: https://github.com/arista-netdevops-community/pre-commit-hooks
  rev: <rev>
  hooks:
    - id: cargo-about
      name: Generate third-party Rust licenses
      args:
        - generate
        - --locked
        - -o
        - pyavd_utils/THIRD_PARTY_LICENSES.txt
        - about-text.hbs

Let pre-commit report changed files. The adapter uses cargo-about's default license-resolution behavior and does not expose --fail or its other CLI commands and options.
