Interfaces
- HasOffset
- Implemented by any exception that can report a byte/character offset into the source it failed on (lexer/parser errors) -- lets {@see DXNError::wrap()} preserve that offset without needing to know about every concrete exception class in the text/binary pipelines.
- HasCategory
- Implemented by any exception that knows its DXN.md §5 category -- `syntax`, `binary`, `encode/unsupported`, ... -- so {@see DXNError::wrap()} can carry it across without knowing every concrete exception class, the way {@see HasOffset} carries an offset.
