rust-failure-handling

Guides the design and review of Rust failure handling by sorting each failure point into normal absence, recoverable error, or genuine bug; choosing between Option, typed Result enums built with thiserror at library boundaries, and context-rich anyhow errors inside applications; propagating with the question-mark operator and From conversions while preserving cause chains; and policing unwrap, expect, and panic, including the bounded startup-configuration exception. Use when writing, refactoring, or reviewing Rust that can fail, when defining error enums and conversions, or when judging whether a panic is justified. Not for async cancellation and executor failure semantics, panics crossing an FFI boundary, or languages other than Rust.
