Module error 

Error and diagnostic context types returned by drivers and parsers.

See Phase and ErrorContext for the operational metadata that recoverable Error variants carry.

All public error types implement core::fmt::Display for human-readable logging, and Error additionally implements core::error::Error (stabilized in no_std since Rust 1.81) so it composes with ?-propagation chains and downstream error-handling utilities. The Debug impls are still derived for {:?} use inside the driver.
