# Function std::sync::atomic::hint_core_should_pause [−] [src]

    pub fn hint_core_should_pause()

🔬 This is a nightly-only experimental API. (`hint_core_should_pause` #41196)

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.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
