Required methods

fn saturate(self) -> Self::Output

Replaces an overflow error with a saturated value.

Unlike unwrap_or_saturate, this method can be used in cases where the Result error type can encode failures other than overflow and underflow. For example, you cannot saturate a float-to-integer conversion using unwrap_or_saturate as the error might be NotANumber, which doesn't have a meaningful saturation "direction".

The output of this method will be a Result where the error type does not contain overflow conditions. What conditions remain must still be dealt with in some fashion.
