Function core::arch::aarch64::__wfi

pub unsafe fn __wfi()

🔬 This is a nightly-only experimental API. (stdsimd #48556)

This is supported on AArch64 only.

Generates a WFI (wait for interrupt) hint instruction, or nothing.

The WFI instruction allows (but does not require) the processor to enter a low-power state until one of a number of asynchronous events occurs.
