The following libraries are currently supported: ================ =========== ============================ Library Requires Magic string ================ =========== ============================ **Trio** Trio v0.6+ ``"trio"`` **Curio** - ``"curio"`` **asyncio** ``"asyncio"`` **Trio-asyncio** v0.8.2+ ``"trio"`` or ``"asyncio"``, depending on current mode ================ =========== ============================ Returns: A string like ``"trio"``. Raises: AsyncLibraryNotFoundError: if called from synchronous context, or if the current async library was not recognized.
