inspectOption
- Return input directly.
- This value is passed as the input. But it maybe mutated by calling effector.
- Call effector with the inner value of input if input is
Some(T). - This main purpose is to inspect an inner value in a chained function calling. If you don't have to do it, you should not mutate the inner value. if-else statement might be sufficient to mutate the inner value instead of calling this function.
