[src]
pub fn spin_loop_hint()
Save power or switch hyperthreads in a busy-wait spin-loop.
This function is deliberately more primitive than
std::thread::yield_now
and does not directly yield to the
system's scheduler. In some cases it might be useful to use a
combination of both functions. Careful benchmarking is advised.
On some platforms this function may not do anything at all.
