Rust Concurrency & Async Pitfalls and Patterns

Summary

A series of practical articles and guides highlighting the difficulties and gotchas of writing concurrent and asynchronous code in Rust. The content spans from low-level atomic operations to async/await quirks, with illustrative examples and debugging techniques. Despite version gaps, the resources remain valuable for grasping core concepts.

Key Insights

  • Rust’s async/await introduces subtle ownership and lifetime traps—especially around Pin, Unpin, and stackless futures.

  • Shared state and thread-safe operations require deep understanding of atomics, memory ordering, and data races.

  • The lack of proper async trait support (pre-1.75) led to complex workarounds, now mitigated by more recent Rust features.

  • Effective debugging of async code often requires understanding how executors poll futures and manage task wakeups.
