.. _async-backend:
Asynchronous Backend Functions
==============================
Dnspython has a "backend" for Trio, Curio, and asyncio which implements
the library-specific functionality needed by the generic asynchronous
DNS code.
Dnspython attempts to determine which backend is in use by "sniffing" for it
with the ``sniffio`` module if it is installed, otherwise it assumes asyncio
is in use.
