Module: pyot.utils.functools

class async_cached_property

Async equivalent of functools.cached_property, takes an async method and converts it to a cached property that returns an awaitable with the return value.

Usage:

class A:
    @async_cached_property
    async def b(self):
        ...
a = A()
await a.b

class async_generator_property

Modified version of async_property, intended for use in async generators. The return typing of the decorated property is: AsyncGenerator[...]

a = A()
async for _ in a.b:
