Parameters:

• func (Union[Callable[[Input], Awaitable[Output]], Callable[[Input, RunnableConfig], Awaitable[Output]], Callable[[Input, AsyncCallbackManagerForChainRun], Awaitable[Output]], Callable[[Input, AsyncCallbackManagerForChainRun, RunnableConfig], Awaitable[Output]]]) – The function to call.

• input (Input) – The input to the function.

• config (RunnableConfig) – The config to pass to the function.

• run_manager (Optional[AsyncCallbackManagerForChainRun]) – The run manager to pass to the function. Defaults to None.

• **kwargs (Any) – The keyword arguments to pass to the function.

Returns:

The output of the function.

Return type:

Awaitable[Output]
