Welcome to quattro!¶

Four-wheel drive for asyncio.

Release UNRELEASED (What’s new?)

quattro is a collection of small and powerful components for advanced task control in asyncio applications.

Using quattro gives you:

• elegant context managers for deadlines and cancellation: fail_after(), fail_at(), move_on_after() and move_on_at().

• a Deferrer class and defer() function to help with indentation and resource cleanup, like in Go.

• a TaskGroup subclass with support for background tasks.

• a safer gather() implementation.

quattro is influenced by structured concurrency concepts from the Trio framework.
