Rust development patterns, ownership, async, error handling, and ecosystem. Use for: rust, cargo, ownership, borrow checker, lifetime, tokio, serde, trait, Result, Option, async rust, crate, derive, impl, enum, pattern matching, Arc, Mutex, Send, Sync, thiserror, anyhow, clap, axum, sqlx, reqwest, rayon, tracing.
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 Operations Comprehensive Rust skill covering ownership, async, error handling, and the production ecosystem. > Ecosystem facts verified as of 2026-07. **Staleness check:** `python scripts/check-rust-facts.py --offline` asserts the catalogued version-bearing facts (tokio, axum, serde) are still named in the prose and the dated currency note above is present; run `--live` to confirm each crate's crates.io major still matches the documented major. Catalog: `assets/rust-facts.json`. ## Ownership Quick Reference ``` Who owns the value? │ ├─ Need to transfer ownership │ └─ Move: let s2 = s1; (s1 is invalid after this) │ ├─ Need to read without owning │ └─ Shared borrow: &T (multiple allowed, no mutation) │ ├─ Need to mutate without owning │ └─ Exclusive borrow: &mut T (only one, no other borrows) │ ├─ Need to share ownership across threads │ └─ Arc<T> (atomic reference counting) │ └─ Need mutation too? Arc<Mutex<T>> │ ├─ Need to share ownership single-threaded │ └─ Rc<T> (reference counting, not Send) │ └─ Need mutation too? Rc<RefCell<T>> │ └─ Need to avoid cloning large data └─ Cow<'a, T> (clone-on-write, borrows when possible) ``` ### The Borrow Rules …

How to install
mdr add 0xdarkmatter/claude-mods/rust-ops@sha256:126fe1b4dd38c34fThe line at the top of this page pins the label git:20260705.864fcdf, 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.
