Async‑trait lets you write async methods in traits by boxing the future. This guide explains its purpose, typical use cases, performance trade‑offs, and when to prefer manual Future implementations.
A decision guide for choosing between Ceylon’s universal type 'any' and safer alternatives like unions, variance‑annotated generics, or traits when designing heterogeneous collections.
Transitioning to Native Async Traits The stabilization of async fn in traits (AFIT) in Rust 1.75 allows developers to define asynchronous methods directly within traits without relying on the #[async_trait] macro. This change moves the implementation from a boxing-based approach to a compiler-generated state machine. While native support reduces dependency o
