colour.hints.NoReturn#
- colour.hints.NoReturn = typing.NoReturn[source]#
Special type indicating functions that never return.
Example:
from typing import NoReturn def stop() -> NoReturn: raise Exception('no way')
NoReturn can also be used as a bottom type, a type that has no values. Starting in Python 3.11, the Never type should be used for this concept instead. Type checkers should treat the two equivalently.
