rust-async-patterns
Master Rust async programming with Tokio, async traits, error handling, and concurrent patterns. Use when building async Rust applications, implementing concurrent systems, or debugging async code.
Why this skill is useful
Provides specific patterns and examples for async Rust programming with Tokio that the AI wouldn't reliably generate on its own.
What it needs
Requires rust installed locally. About 6k tokens when loaded. Last updated 2026-08-07. 405 stars on the source repository.
What this skill does
Rust Async Patterns Production patterns for async Rust programming with Tokio runtime, including tasks, channels, streams, and error handling. When to Use This Skill Building async Rust applications Implementing concurrent network services Using Tokio for async I/O Handling async errors properly Debugging async code issues Optimizing async performance Core Concepts 1. Async Execution Model 2. Key Abstractions Concept Purpose --------- --------- Future Lazy computation that may complete later async fn Function returning impl Future await Suspend until future completes Task Spawned future running concurrently Runtime Executor that polls futures Quick Start Patterns Pattern 1: Concurrent Task Execution Pattern 2: Channels for Communication Pattern 3: Async Error Handling Pattern 4: Graceful Shutdown Pattern 5: Async Traits Pattern 6: Streams and Async Iteration Pattern 7: Resource Management Debugging Tips Best Practices Do's Use tokio::select! - For racing futures Prefer channels - Over shared state when possible Use JoinSet - For managing multiple tasks Instrument with tracing - For debugging async code Handle cancellation - Check CancellationToken Don'ts Don't block - Never use std::thread::sleep in async Don't hold locks across awaits - Causes deadlocks Don't spawn unboundedly - Use semaphores for limits Don't ignore errors - Propagate with ? or log Don't forget Send bounds - For spawned futures Resources Tokio Tutorial Async Book Tokio Console
