Function az::overflowing_cast [−][src]
pub fn overflowing_cast<Src: OverflowingCast<Dst>, Dst>(src: Src) -> (Dst, bool)
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));
