Detailed Description

Hash function for OpenMS::AASequence.

Computes a hash based on the amino acid sequence (one-letter codes), modifications on each residue, and terminal modifications.

Design decisions:

• Uses one-letter codes instead of pointers for portability
• Includes modification IDs for modified residues
• Includes terminal modifications
• Hash is consistent with operator==

Note

Hash is reproducible across process runs for equal sequences.
