/// Represents the outer-level, user-facing errors of the tycho-execution encoding package.
///
/// `EncodingError` encompasses all possible errors that can occur in the package,
/// wrapping lower-level errors in a user-friendly way for easier handling and display.
/// Variants:
/// - `InvalidInput`: Indicates that the encoding has failed due to bad input parameters.
/// - `FatalError`: There is problem with the application setup.
/// - `RecoverableError`: Indicates that the encoding has failed with a recoverable error. Retrying
///   at a later time may succeed. It may have failed due to a temporary issue, such as a network
///   problem.
