Trait PinCurrentCpu

Source 
pub unsafe trait PinCurrentCpu {
    // Provided method
    fn current_cpu(&self) -> CpuId { ... }
}
Expand description

A marker trait for guard types that can “pin” the current task to the current CPU.

Such guard types include DisabledLocalIrqGuard and DisabledPreemptGuard. When such guards exist, the CPU executing the current task is pinned. So getting the current CPU ID or CPU-local variables are safe.

§Safety

The implementor must ensure that the current task is pinned to the current CPU while any one of the instances of the implemented structure exists.

Provided Methods§

Source

fn current_cpu(&self) -> CpuId

Returns the ID of the current CPU.
