Function std::intrinsics::cttz_nonzero [−][src]
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
Like cttz, but extra-unsafe as it returns undef when
given an x with value 0.
This intrinsic does not have a stable counterpart.
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);Run
