Trait CheckedShr 

pub trait CheckedShr: Sized + Shr<u32> {
    // Required method
    fn checked_shr(self, rhs: u32) -> Option<<Self as Shr<u32>>::Output>;
}

Performs shift right, returning None on shifts larger than or equal to the type width.

Required Methods

fn checked_shr(self, rhs: u32) -> Option<<Self as Shr<u32>>::Output>

Checked shift right. Computes self >> rhs, returning None if rhs is larger than or equal to the number of bits in self.

use const_num_traits::CheckedShr;

let x: u16 = 0x8000;

assert_eq!(CheckedShr::checked_shr(x, 0),  Some(0x8000));
assert_eq!(CheckedShr::checked_shr(x, 1),  Some(0x4000));
assert_eq!(CheckedShr::checked_shr(x, 15), Some(0x0001));
assert_eq!(CheckedShr::checked_shr(x, 16), None);

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
