What's Good
Battle-tested at scale by Discord, Cloudflare, and more. The ecosystem (Axum, Tonic, Tower) is comprehensive. Work-stealing scheduler is efficient. The documentation is excellent.
The Catch
Async Rust has a learning curve. Stack traces are confusing. Some patterns from other languages do not translate.
Verdict
The async runtime that powers production Rust.
