devel/py-txaio 26.6.1 NetBSD

txaio is a helper library for writing code that runs unmodified on both Twisted and asyncio / Trollius.

This is like six, but for wrapping over differences between Twisted and asyncio so one can write code that runs unmodified on both (aka source code compatibility). In other words: your users can choose if they want asyncio or Twisted as a dependency.

Note that, with this approach, user code runs under the native event loop of either Twisted or asyncio. This is different from attaching either one's event loop to the other using some event loop adapter.
