sniffio: Sniff out which async library your code is running under
You’re writing a library. You’ve decided to be ambitious, and support multiple async I/O packages, like Trio, and asyncio, and … You’ve written a bunch of clever code to handle all the differences. But… how do you know which piece of clever code to run?
This is a tiny package whose only purpose is to let you detect which async library your code is running under.

Code of conduct: Contributors are requested to follow our code of conduct in all project spaces.
This library is maintained by the Trio project, as a service to the async Python community as a whole.
Quickstart
from sniffio import current_async_library
import trio
import asyncio
async def print_library():
library = current_async_library()
print("This is:", library)
# Prints "This is trio"
trio.run(print_library)
# Prints "This is asyncio"
asyncio.run(print_library())For more details, including how to add support to new async libraries, please peruse our fine manual.
