Decorators for manipulating function signatures.

Functions:

Name	Description
`method_signature_of`	Set the signature of the decorated function to the signature of the given function, but preserve the first parameter of the
`return_of`	Copy only the return type of the given function.
`signature_of`	Return a decorator that sets the signature of the decorated function to the signature of the given function.

method_signature_of ¶

method_signature_of(
    _: Callable[Concatenate[Any, P], Any],
) -> Callable[
    [Callable[Concatenate[T, ...], R]],
    Callable[Concatenate[T, P], R],
]

Set the signature of the decorated function to the signature of the given function, but preserve the first parameter of the signature. Use this when decorating methods.

Returns:

Type	Description
`Callable[[Callable[Concatenate[T, ...], R]], Callable[Concatenate[T, P], R]]`	A signature changing decorator.

return_of ¶

return_of(
    _: Callable[..., T],
) -> Callable[[Callable[P, Any]], Callable[P, T]]

Copy only the return type of the given function.

Returns:

Type	Description
`Callable[[Callable[P, Any]], Callable[P, T]]`	A signature changing decorator.

signature_of ¶

signature_of(
    _: Callable[P, Any],
) -> Callable[[Callable[..., R]], Callable[P, R]]

Return a decorator that sets the signature of the decorated function to the signature of the given function.

Returns:

Type	Description
`Callable[[Callable[..., R]], Callable[P, R]]`	A signature changing decorator.
