• GraphStoreConstraintViolationError – A write violated a uniqueness constraint the backend enforces.
• GraphStoreDataIntegrityError – A read found the graph store in a state its own invariants forbid.
• GraphStoreError – The base class for every graph-store error.
• GraphStoreMissingExtraError – A graph store exists, but its package extra is not installed.
