Trait ShrExact 

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

Performs a lossless (exactly reversible) right shift.

Required Methods

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

Exact shift right. Computes self >> rhs if no one-bits would be shifted out (so the operation can be losslessly reversed), None otherwise.

use const_num_traits::ShrExact;

assert_eq!(ShrExact::shr_exact(0x88u8, 3), Some(0x11));
assert_eq!(ShrExact::shr_exact(0x88u8, 4), None);

Dyn Compatibility

This trait is not dyn compatible.

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