Function asyncify

src/anthropic/_utils/_sync.py:28–58

Take a blocking function and create an async one that receives the same positional and keyword arguments. Usage: ```python def blocking_func(arg1, arg2, kwarg1=None): # blocking code return result result = asyncify(blocking_function)(arg1, arg2, kwarg1=va

(function: Callable[T_ParamSpec, T_Retval])

# inspired by `asyncer`, https://github.com/tiangolo/asyncer

    Take a blocking function and create an async one that receives the same
    positional and keyword arguments.

    Usage:

    ```python
    def blocking_func(arg1, arg2, kwarg1=None):
        # blocking code
        return result


    result = asyncify(blocking_function)(arg1, arg2, kwarg1=value1)
    ```

    ## Arguments

    `function`: a blocking regular callable (e.g. a function)

    ## Return

    An async function that takes the same positional and keyword arguments as the
    original one, that when called runs the same original function in a thread worker
    and returns the result.
