Trait az::UnwrappedCast

source · 
pub trait UnwrappedCast<Dst> {
    fn unwrapped_cast(self) -> Dst;
}
Expand description

Used to cast values, panicking if the value does not fit.

It is normally easier to use the UnwrappedAs trait instead of this trait.

Panics

This trait’s method panics if the value does not fit in the destination, even when debug assertions are not enabled.

Examples

use az::UnwrappedCast;
let a: u32 = 5i32.unwrapped_cast();
assert_eq!(a, 5);
assert_eq!(UnwrappedCast::<u8>::unwrapped_cast(17.1f32), 17);

The following panics because of overflow.

ⓘ
use az::UnwrappedCast;
let _overflow: u32 = (-5i32).unwrapped_cast();
