pub const extern "rust-intrinsic" fn ctpop<T: Copy>(x: T) -> u32🔬This is a nightly-only experimental API. (
core_intrinsics)Expand description
Returns the number of bits set in an integer type T
Note that, unlike most intrinsics, this is safe to call;
it does not require an unsafe block.
Therefore, implementations must not require the user to uphold
any safety invariants.
The stabilized versions of this intrinsic are available on the integer
primitives via the count_ones method. For example,
u32::count_ones
