Function decode_edit 

pub fn decode_edit(input: &[u8]) -> Result<Edit<'_>, DecodeError>

Decodes an Edit from binary data with zero-copy borrowing.

Handles both compressed (GRC2Z) and uncompressed (GRC2) formats. For true zero-copy with compressed data, use decompress first:

// Zero-copy for compressed data:
let uncompressed = decompress(&compressed)?;
let edit = decode_edit(&uncompressed)?;

// Zero-copy for uncompressed data:
let edit = decode_edit(&uncompressed_bytes)?;

If you pass compressed data directly, it will decompress internally and allocate owned strings (no zero-copy benefit).
