Detailed Description

The ExecutionSignature tag to use to get the visit index.

When a worklet is dispatched, there is a scatter operation defined that optionally allows each input to go to multiple output entries. When one input is assigned to multiple outputs, there needs to be a mechanism to uniquely identify which output is which. The visit index is a value between 0 and the number of outputs a particular input goes to. This tag in the ExecutionSignature passes the visit index for this work. WorkletBase contains a typedef that points to this class.
