4//! Error types used by this crate.
5//!
6//! [`Error`] is a wrapper enum for all error types that are used.
7//!
8//! The two main classes of errors are:
9//! - [`SmartcardError`], for problems on the reader/smartcard layer
10//! - [`StatusBytes`], which models error statuses reported by the OpenPGP
11//!   card application
