RarArchive (GenericBinary, FilesystemRoot) dataclass

Filesystem stored in a RAR archive.

RarUnpacker (Unpacker)

Unpack RAR archives using the free unrar tool.

unpack(self, resource, config=None) async

Unpack the given resource.

Users should not call this method directly; rather, they should run or Resource.unpack.


Name Type Description Default
resource Resource

The resource that is being unpacked

config ComponentConfig

Optional config for unpacking. If an implementation provides a default, this default will always be used when config would otherwise be None. Note that a copy of the default config will be passed, so the default config values cannot be modified persistently by a component run.
