Function std::intrinsics::unchecked_shl

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

Performs an unchecked left shift, resulting in undefined behavior when y < 0 or y >= N, where N is the width of T in bits.

Safe wrappers for this intrinsic are available on the integer primitives via the checked_shl method. For example, u32::checked_shl
