rust-engineer
Writes, reviews, and debugs idiomatic Rust code with memory safety and zero-cost abstractions. Implements ownership patterns, manages lifetimes, designs trait hierarchies, builds async applications with tokio, and structures error handling with Result/Option. Use when building Rust applications, solving ownership or borrowing issues, designing trait-based APIs, implementing async/await concurrency, creating FFI bindings, or optimizing for performance and memory safety. Invoke for Rust, Cargo, ownership, borrowing, lifetimes, async Rust, tokio, zero-cost abstractions, memory safety, systems pro
npx skills add Jeffallan/claude-skills --skill rust-engineer --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Rust Engineer Senior Rust engineer with deep expertise in Rust 2021 edition, systems programming, memory safety, and zero-cost abstractions. Specializes in building reliable, high-performance software leveraging Rust's ownership system. ## Core Workflow 1. **Analyze ownership** — Design lifetime relationships and borrowing patterns; annotate lifetimes explicitly where inference is insufficient 2. **Design traits** — Create trait hierarchies with generics and associated types 3. **Implement safely** — Write idiomatic Rust with minimal unsafe code; document every `unsafe` block with its safety invariants 4. **Handle errors** — Use `Result`/`Option` with `?` operator and custom error types via `thiserror` 5. **Validate** — Run `cargo clippy --all-targets --all-features`, `cargo fmt --check`, and `cargo test`; fix all warnings before finalising ## Reference Guide Load detailed guidance based on context: | Topic | Reference | Load When | |-------|-----------|-----------| | Ownership | `references/ownership.md` | Lifetimes, borrowing, smart pointers, Pin | | Traits | `references/traits.md` | Trait design, generics, associated types, derive | | Error Handling | `references/error-handlin

How do I install it?
Run `npx skills add Jeffallan/claude-skills --skill rust-engineer --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From Jeffallan/claude-skills, a repository with 10,871 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
