A structure (LV2_Worker_Interface) which contains the worker method to be called by the host. In order to support this extension, the plugin must return a valid LV2_Worker_Interface from LV2_Descriptor::extension_data() when it is called with URI LV2_WORKER__Interface.

The plugin data file should describe this like so:

@prefix work: <http://lv2plug.in/ns/ext/worker#> .

<plugin>
    a lv2:Plugin ;
    lv2:extensionData work:Interface .
""" . work:schedule a lv2:Feature ; lv2:documentation """

A feature which provides functions for use by the plugin to implement a worker method. To support this feature, the host must pass an LV2_Feature to LV2_Descriptor::instantiate() with URI LV2_WORKER__schedule and data pointed to an instance of LV2_Worker_Schedule.
