std::intrinsics::cttz_nonzero - Rust
Description: API documentation for the Rust `cttz_nonzero` fn in crate `std`.
Keywords: rust, rustlang, rust-lang, cttz_nonzero

# [−][src]Function std::intrinsics::cttz_nonzero

    pub 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);
