尽管如此，Uvicorn 目前仅与 asyncio 兼容，并且通常使用 <a href="https://github.com/MagicStack/uvloop" class="external-link" target="_blank">`uvloop`</a >, 它是`asyncio`的高性能替代品。

但如果你想直接使用**Trio**，那么你可以使用**Hypercorn**，因为它支持它。 ✨

It was one of the first extremely fast Python frameworks based on `asyncio`. It was made to be very similar to Flask.

!!! note "Technical Details"
    It used <a href="https://github.com/MagicStack/uvloop" class="external-link" target="_blank">`uvloop`</a> instead of the default Python `asyncio` loop. That's what made it so fast.

### Create the *path operation function*

As our code is calling Couchbase and we are not using the <a href="https://docs.couchbase.com/python-sdk/2.5/async-programming.html#asyncio-python-3-5" class="external-link" target="_blank">experimental Python <code>await</code> support</a>, we should declare our function with normal `def` instead of `async def`.
