+Metadata-Version: 1.1
+Name: async_timeout
+Version: 1.0.0
+Summary: Timeout context manager for asyncio programs
+Home-page: https://github.com/aio-libs/async_timeout/
+Author: Andrew Svetlov

+License: Apache 2
+Description: async_timeout
+ =============
+
+ asyncio-compatible timeout context manager.
+
+
+ Usage example
+ -------------
+
+
+ The context manager is useful in cases when you want to apply timeout
+ logic around block of code or in cases when ``asyncio.wait_for()`` is
+ not suitable. Also it's much faster than ``asyncio.wait_for()``
+ because ``timeout`` doesn't create a new task.
+
+ The ``timeout(timeout, *, loop=None)`` call returns a context manager
+ that cancels a block on *timeout* expiring::
+
+ with timeout(1.5):
+ yield from inner()
+
+ 1. If ``inner()`` is executed faster than in ``1.5`` seconds nothing
+ happens.
+ 2. Otherwise ``inner()`` is cancelled internally by sending
+ ``asyncio.CancelledError`` into but ``asyncio.TimeoutError`` is
+ raised outside of context manager scope.
+
+ *timeout* parameter could be ``None`` for skipping timeout functionality.
+
+ Installation
+ ------------
+
+ ::
+
+ $ pip install async_timeout
+
+ The library is Python 3 only!
