rust

name	rust
description	Auto-apply when working with Rust. Trigger this skill when the user asks to create, modify, or debug Rust code, Cargo projects, crates, or Rust tests.

Lang: Rust

Rules

1. Safety: NEVER use .unwrap(). Use ? propagation or .expect("msg").
2. Style: Prefer Iterators (.map().collect()) over for loops.
3. Async: Assume tokio. Use .await. Never block async threads.
4. Errors: Use anyhow::Result for apps, thiserror for libs.
5. Tests: Co-locate unit tests in mod tests with #[cfg(test)].
6. Clippy: Code must be strictly clippy-compliant (idiomatic).

Workflow

• Use skill workflow-env before build/run commands.
• Build: cargo build --release
• Test: cargo test
• Format: cargo fmt
