1//! Typed error enum for cargo-truce.
2//!
3//! Callers pattern-match on the failure mode (missing tool, codesign
4//! failure, manifest parse error, etc.) instead of string-grepping a
5//! `Box<dyn Error>` Display output. The catch-all `Other` variant
6//! carries stringly-typed errors from `Err("...".into())` sites that
7//! haven't been migrated to a named variant; `From<String>` and
8//! `From<&str>` conversions keep `?` propagation transparent.
