duet
A simple future-based async library for python
Duet takes inspiration from the amazing trio library and the structured concurrency approach to async programming that it uses. However, duet differs from trio in two major ways:
-
Instead of a full-blown implementation of asynchronous IO, duet relies on the
Futureinterface for parallelism, and provides a way to run async/await coroutines around thoseFutures. This is useful if you are using an API that returns futures, such as RPC libraries like gRPC. The standardFutureinterface does not implement__await__directly, soFutureinstances must be wrapped induet.AwaitableFuture. -
duet is re-entrant. At the top level, you run async code by calling
duet.run(foo). Insidefoosuppose you call a function that has not yet been fully refactored to be asynchronous, but itself callsduet.run(bar). Most async libraries, includingtrioandasyncio, will raise an exception if you try to "re-enter" the event loop in this way, but duet allows it. We have found that this can simplify the process of refactoring code to be asynchronous because you don't have to completely separate the sync and async parts of your codebase all at once.
