Function hurray_buffer_memory_class 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn hurray_buffer_memory_class(
    buffer: *const HurrayBuffer,
    out_memory_class: *mut u8,
) -> HurrayStatus

Reads the memory class wire byte of a buffer handle.

Safety

buffer and out_memory_class MUST be valid, non-null pointers.
