Ergonomic errors in Rust: write fast, debug with ease, handle precisely
Downcasting requires you to know the concrete source error type and where it’s wrapped; the compiler can’t help you, and if internals change your branches silently stop matching. That isn’t just nicer to read, it avoids the “stop coding, go add an enum variant elsewhere, come back” loop that error-enum designs often force. Rust gives us powerful building blocks for errors, but day-to-day work benefits from a pattern that stays ergonomic while scaling: write with minimal friction, debug with clear stacked context, and handle at runtime by matching on well-typed codes.
