Function std::intrinsics::cttz_nonzero

pub const unsafe extern "rust-intrinsic" fn cttz_nonzero<T>(x: T) -> T where
    T: Copy, 

🔬 This is a nightly-only experimental API. (core_intrinsics)

intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

类似于 cttz，但是非常不安全，因为当给定值 0 的 x 时，它返回 undef。

此内联函数没有稳定的对应对象。

Examples

#![feature(core_intrinsics)]

use std::intrinsics::cttz_nonzero;

let x = 0b0011_1000_u8;
let num_trailing = unsafe { cttz_nonzero(x) };
assert_eq!(num_trailing, 3);
