Version CRUD operations.

Functions

create_version

Create a new version. Returns the version ID.

delete_version

ensure_entity_exists

Check that an entity exists. Returns error if not found.

ensure_relation_exists

Check that a relation exists. Returns error if not found.

ensure_version_exists

Check that a version exists. Returns error if not found.

get_version

Get a version by ID. Returns Error::VersionNotFound if no such version exists.

list_versions

List versions, optionally filtered by branch.

version_bit_for

Resolve a version id to its validity bitmask (1 << bit_slot).

versions_for_bits

Return every version whose bit_slot is set in bits, newest first.
