Code Style

Every change must be formatted and lint-clean before it is committed. CI treats clippy warnings as hard errors, so run the same checks locally to avoid a failed build.

Format with rustfmt

cargo fmt

cargo fmt reformats every Rust source file in the workspace in place. Run it unconditionally after making changes. It is idempotent and fast.

Lint with Clippy

cargo clippy --all-targets --all-features -- -D warnings

The flags matter:

• --all-targets checks library code, binaries, tests, and examples.
• --all-features enables every Cargo feature flag so no code path is skipped.
• -- -D warnings promotes every clippy warning to a hard error, which matches CI behavior.

Fix every diagnostic clippy reports before proceeding. Do not suppress warnings with #[allow(...)] unless there is a genuine false positive. If you do add one, include a comment explaining why.

Shorthand via just

Both steps can be run together with a single recipe:

just lint

This is equivalent to running cargo fmt followed by the full clippy invocation above.

Related recipes:

• just fmt reformats without linting.
• just clippy lints without reformatting.
• just test-everything additionally runs the full unit and integration test suites on top of linting.

Checklist

Before committing, confirm:

• cargo fmt applied, with no unformatted files remaining.
• cargo clippy --all-targets --all-features -- -D warnings exits with code 0.
• No #[allow(...)] annotations added without an explanatory comment.
