Hidden Traps of Async Traits in Rust: A Journey of Performance Optimization
Introduction In Rust’s asynchronous programming, async traits appear to be an elegant abstraction tool that allows us to write concise asynchronous code. However, when we refactored the service mesh proxy from concrete types to async traits, we encountered catastrophic performance issues: memory usage skyrocketed by 340%, throughput dropped by 89%, and latency surged from 2ms … Read more
