The article examines the common pain points in Rust error handling, particularly the trade-off between precise enum-based error types with boilerplate versus convenient box error types that lose specificity. The author argues that error types should compose as naturally as the functions that produce them, proposing a middle ground between thiserror and anyhow approaches.
Background
Rust's error handling via Result<T, E> is considered one of its standout features, but many developers struggle with the ergonomics of composing error types across layers of an application.
