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.

To find out why you might want to use AnyIO's APIs instead of asyncio's, you can read about it
`here <https://anyio.readthedocs.io/en/stable/why.html>`_.

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
* Subinterpreter support for code parallelization (on Python 3.13 and later)
* Asynchronous file I/O (using worker threads)
* Signal handling
* Asynchronous version of the functools_ module

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