AnyIO is an asynchronous networking and concurrency library that works on top of either asyncio_ or trio_. It implements trio-like structured concurrency_ (SC) on top of asyncio and works in harmony with the native SC of trio itself.

Applications and libraries written against AnyIO's API will run unmodified on either asyncio_ or trio_. AnyIO can also be adopted into a library or application incrementally – bit by bit, no full refactoring necessary. It will blend in with the native libraries of your chosen backend.

Features

AnyIO offers the following functionality:

• Task groups (nurseries_ in trio terminology)

• High-level networking (TCP, UDP and UNIX sockets)

  • Happy eyeballs_ algorithm for TCP connections (more robust than that of asyncio on Python 3.8)
  • async/await style UDP sockets (unlike asyncio where you still have to use Transports and Protocols)

• A versatile API for byte streams and object streams

• Inter-task synchronization and communication (locks, conditions, events, semaphores, object streams)

• Worker threads

• Subprocesses

• Asynchronous file I/O (using worker threads)

• Signal handling

AnyIO also comes with its own pytest_ plugin which also supports asynchronous fixtures. It even works with the popular Hypothesis_ library.
