betty.asyncio module¶
Provide asynchronous programming utilities.
- async betty.asyncio.gather(*coroutines: Coroutine[Any, None, betty.asyncio.T]) tuple[betty.asyncio.T, ...] [source]¶
Gather multiple coroutines.
This is like Python’s own
asyncio.gather
, but with improved error handling.- Parameters:
coroutines (
typing.Coroutine
[typing.Any
,None
,typing.TypeVar
(T
)])- Return type:
tuple
[typing.TypeVar
(T
),...
]
- betty.asyncio.sync(f: Callable[[P], Awaitable[betty.asyncio.T]]) Callable[[P], betty.asyncio.T] [source]¶
Decorate an asynchronous callable to become synchronous.
- Parameters:
f (
typing.Callable
[[typing.ParamSpec
(P
, bound=None
)],typing.Awaitable
[typing.TypeVar
(T
)]])- Return type:
typing.Callable
[[typing.ParamSpec
(P
, bound=None
)],typing.TypeVar
(T
)]
- betty.asyncio.wait(f: Awaitable[betty.asyncio.T]) betty.asyncio.T [source]¶
Wait for an awaitable, either in a new event loop or another thread.
- Parameters:
f (
typing.Awaitable
[typing.TypeVar
(T
)])- Return type:
- betty.asyncio.wait_to_thread(f: Awaitable[betty.asyncio.T]) betty.asyncio.T [source]¶
Wait for an awaitable in another thread.
- Parameters:
f (
typing.Awaitable
[typing.TypeVar
(T
)])- Return type:
