This technical blog post explores the issue of 'async bloat' in Rust, where async code can lead to excessive memory usage, reduced performance, or larger binary sizes in certain scenarios. The author discusses common problems encountered in serverless applications, high-performance servers, and embedded systems, and promises to provide solutions for optimizing async Rust code. This addresses practical concerns for developers working with async Rust in production environments.
Background
Async Rust enables concurrent programming without manual state machine management, but can introduce performance and memory overhead issues in certain applications. Developers often encounter these problems when scaling async applications in resource-constrained environments.
