Module bus 

Structs

Bus

Cross-thread event channel. Once a buffer crosses a Queue boundary, errors can no longer be propagated up the call stack with ? — they’re posted here instead so the owner of the Pipeline can observe them.

BusMessage

One bus event together with the stable graph identity of the element that posted it. Drivers and standalone elements that do not belong to a PipelineGraph use None.
