Module tables 

Table structs for per-atom, per-residue, and per-chain data.

These tables hold topology data that is constant across trajectory frames. All tables use struct-of-arrays (SoA) layout for cache-friendly iteration.

Structs

AtomsTable

Per-atom topology data (not coordinates — those live in AtomicConformation).

ChainsTable

Per-chain topology data.

ResiduesTable

Per-residue topology data.

Enums

ResidueGroup

Residue classification: polymer (protein/nucleic acid) or non-polymer (ligand/solvent).

Constants

MISSING_SEQ_ID

Sentinel used when an mmCIF sequence identifier is explicitly missing (. or ?).
