Use when implementing or debugging Rust threads, Send/Sync bounds, Arc and synchronization, channels, Tokio async tasks, cancellation, graceful shutdown, backpressure, deadlocks, or choosing Rayon for CPU-bound parallel work.
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.

# Rust Concurrency ## Quick reference | Need or symptom | Start with | Read next | |---|---|---| | Independent blocking work or a persistent worker | Owned OS thread; explicit join/shutdown | [Threads and shared state](references/threads-and-state.md) | | Parallel work borrowing caller-owned data | `std::thread::scope`; split disjoint mutable slices | [Threads and shared state](references/threads-and-state.md) | | Move work to one resource owner | Bounded channel; close, drain, join | [Threads and shared state](references/threads-and-state.md) | | Share immutable data / a compound mutable invariant | `Arc<T>` / `Arc<Mutex<T>>`, with the required bounds | [Threads and shared state](references/threads-and-state.md) | | Many concurrent I/O operations | Existing async runtime; bound admission and task count | [Async lifecycle](references/async-lifecycle.md) | | `future cannot be sent between threads safely` | Inspect captures and state retained across suspension | [Async lifecycle](references/async-lifecycle.md) | | Timeout, task cancellation, service shutdown | Identify the operation being dropped and its partial effects | [Async lifecycle](references/async-lifecycle.md) | …

How to install
mdr add lu1sdv/skillsmd/rust-concurrency@sha256:295e04b5d9c744d7The line at the top of this page pins the label git:20261103.3acb4ab, 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.
