Expand description

PerCpuVariants is a trait for per-cpu data structures.

Required Methods§

Source

fn get(&self) -> &T

Get the per-cpu data for the current CPU.

Source

fn get_mut(&self) -> &mut T

Get the per-cpu data for the current CPU.

Source

unsafe fn force_get(&self, cpu: u32) -> &T

Get the per-cpu data for the given CPU.

§Safety

This function is unsafe because it allows access to the per-cpu data for a CPU that may not be the current CPU. The caller must ensure that the CPU is valid and that the data is not accessed from a different CPU.

Source

unsafe fn force_get_mut(&self, cpu: u32) -> &mut T

Get the per-cpu data for the given CPU.

§Safety

This function is unsafe because it allows access to the per-cpu data for a CPU that may not be the current CPU. The caller must ensure that the CPU is valid and that the data is not accessed from a different CPU.
