language-rust from lugassawan/swe-workbench is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add lugassawan/swe-workbench/language-rust@git:20260828.71a6399Pins git:20260828.71a6399 in mdr.lock. Pin the fingerprint instead.

Rust idioms — ownership, lifetimes, and iterators. Auto-load when working with .rs files, Cargo.toml, or when the user mentions Rust, cargo, ownership, borrow checker, lifetime, or async Rust.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Rust ## Ownership in one paragraph Every value has one owner. Passing by value moves; borrow with `&` (shared, many) or `&mut` (exclusive, one). Shared and mutable references cannot coexist. Most "fights with the borrow checker" are a design smell — the data model mixed ownership and sharing. ## Borrowing rules of thumb - `&T` when you only read. - `&mut T` when you mutate in place. - `T` (by value) when you consume — builders, transforming constructors. - Return owned types unless the caller clearly benefits from a borrow tied to a parameter's lifetime. ## Lifetimes - Start without annotations; add them when the compiler asks. - `'static` does not mean "lives forever" — it means "no non-static references inside". Prefer owned types over `'static` juggling. - If a struct needs many lifetimes, consider owned data or `Arc` instead. ## Error handling - Return `Result<T, E>`; use `?` to propagate. - **Library code:** custom enum with `thiserror`. - **Application code:** `anyhow::Error` for ergonomics; add context with `.with_context(|| "doing X")`. - Reserve `panic!` for invariant violations the caller cannot recover from. ```rust #[derive(thiserror::Error, Debug)] …

How to install
mdr add lugassawan/swe-workbench/language-rust@sha256:039bb0b4dba66b1aThe line at the top of this page pins the label git:20260828.71a6399, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
