name rust-async-patterns description 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. 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 Future (lazy) → poll() → Ready(value) | Pending ↑ ↓ Waker ← Runtime schedules 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 # Cargo.toml [dependencies] tokio = { version = "1" , features = [ "full" ] } futures = "0.3" async-trait = "0.1" anyhow = "1.0" tracing = "0.1" tracing-subscriber = "0.3" use tokio::time::{sleep, Duration}; use anyhow:: Result ; #[tokio::main] async fn main () -> Result <()> { // Initialize tracing tracing_subscriber::fmt:: init (); // Async operations let result = fetch_data ( "https://api.example.com" ). await ?; println! ( "Got: {}" , result); Ok (()) } async fn fetch_data (url: & str ) -> Result < String > { // Simulated async operation sleep (Duration:: from_millis ( 100 )). await ; Ok ( format! ( "Data from {}" , url)) } Detailed patterns and worked examples Detailed pattern documentation lives in references/details.md . Read that file when the navigation tier above is insufficient. 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
