Function az::overflowing_cast
source · [−]pub fn overflowing_cast<Src: OverflowingCast<Dst>, Dst>(src: Src) -> (Dst, bool)Expand description
Overflowing cast.
Returns a tuple of the value and a bool, indicating whether
an overflow has occurred. On overflow, the wrapped value is
returned.
Panics
Panics if the value does not fit and cannot be wrapped, for example when trying to cast floating-point ∞ into an integer type.
Examples
assert_eq!(az::overflowing_cast::<i32, u32>(-1), (u32::max_value(), true));
assert_eq!(az::overflowing_cast::<f32, u8>(17.0 + 256.0), (17, true));
