Packer (AbstractComponent, ABC)

Packers are components that typically mirror unpackers, taking constituent children resources (and sometimes descendants) and reassembling them to produce a new resource.

pack(self, resource, config) async

Pack the given resource.

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

Parameters:

Name	Type	Description	Default
resource	Resource		required
config	~CC	Optional config for packing. 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.	required
