async-interrupt 1.2.0

Context manager to raise an exception when a future is done

async_interrupt

Interrupt context manager for asyncio.

This module provides a context manager that can be used to interrupt a block of code as soon as possible when a future is done.

The purpose is to raise as soon as possible to avoid any race conditions.

This is based loosely on async_timeout by Andrew Svetlov and cpython asyncio.timeout

Usage

async with interrupt(future, ValueError, "message"):
    future.set_result(None)
    await asyncio.sleep(0)

Installation

Install this via pip (or your favourite package manager):

pip install async_interrupt
