The author discusses the limitations of existing Rust error handling crates (anyhow, thiserror, snafu, exn) and introduces their new 'scoped-error' crate. The new solution aims to address verbosity, context attachment, and error type coupling issues while providing better ergonomics for per-module error handling.
Background
