In the previous chapters, we learned about asynchronous interfaces to standard library components (or even completely new APIs) that, in the broader sense, keep shareable state/context or are “runnable”. This includes:
Coroutines
Tasks
Async generators
Async context managers
Async comprehensions
Subprocesses
These components might need to share their state with other instances of asyncio components. Examples where this makes sense include:
Coroutine workers
State-machine or state-keeping coroutines, such as an audio player (playing/paused/idle) ...
