Scoped Error in Rust
Summary
The article introduces a Rust crate called scoped-error that aims to simplify error handling by attaching context only once at module boundaries. It compares common Rust error crates (anyhow, thiserror, snafu, exn) and shows how to wrap and box errors to produce a readable error tree. A minimal core is provided, with examples of using expect_error and a module-scoped Error type.
