class swh.alter.operations.Removable(removable_swhids: List[ExtendedSWHID], referencing: List[ExtendedSWHID])[source]#

Bases: NamedTuple

Aggregates information returned by Remover.get_removable() to be then used with Remover.create_recovery_bundle().

Create new instance of Removable(removable_swhids, referencing)

removable_swhids: List[ExtendedSWHID]#

Alias for field number 0
