Trait az::CheckedCast

source ·
pub trait CheckedCast<Dst> {
    // Required method
    fn checked_cast(self) -> Option<Dst>;
}
Expand description

Used for checked casts.

This trait’s method returns None if the value does not fit.

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

§Examples

use az::CheckedCast;
use core::f32;

let a: Option<u32> = 5i32.checked_cast();
assert_eq!(a, Some(5));
assert_eq!(CheckedCast::<u32>::checked_cast(-5i32), None);
assert_eq!(CheckedCast::<u8>::checked_cast(17.1f32), Some(17));
let b: Option<u8> = f32::NAN.checked_cast();
assert_eq!(b, None);

Required Methods§

source

fn checked_cast(self) -> Option<Dst>

Casts the value.
