pub const unsafe extern "rust-intrinsic" fn unchecked_shr<T: Copy>( x: T, y: T ) -> T
Performs an unchecked right 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_shr method. For example,
