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
|
|
Future interface for parallelism, and provides a way to run async/await
|
|
coroutines around those Futures. This is useful if you are using an API that
|
|
returns futures, such as RPC libraries like gRPC. The standard Future
|
|
interface does not implement __await__ directly, so Future instances must be
|
|
wrapped in duet.AwaitableFuture.
|
|
|
|
* duet is re-entrant. At the top level, you run async code by calling
|
|
duet.run(foo). Inside foo suppose you call a function that has not yet been
|
|
fully refactored to be asynchronous, but itself calls duet.run(bar). Most
|
|
async libraries, including trio and asyncio, 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.
