No Matching Overload

What it does

Checks for calls to an overloaded function that do not match any of the overloads.

Why is this bad?

Failing to provide the correct arguments to one of the overloads will raise a TypeError at runtime.

Examples

from typing import overload


@overload
def func(x: int): ...
@overload
def func(x: bool): ...
def func(x: int | bool): ...


func("string")  # error: [no-matching-overload]
