data ParseError Source #

Parser errors with detailed context

These errors provide enough information for debugging without exposing internal implementation details to end users.

Constructors

UnsupportedFormat Text

File format not supported (with format details)

CorruptedFile Text

File structure invalid (with corruption details)

IOError Text

IO operation failed (with system error)

PartialParse Text

File partially parsed (common with corrupted MP3s)

InvalidEncoding Text

Text encoding issues (common with old MP3 tags)
