Trait AnyStorage

pub unsafe trait AnyStorage<T> {
    // Required methods
    fn get_ptr_on_current(&self, guard: &DisabledLocalIrqGuard) -> *const T;
    fn get_ptr_on_target(&self, cpu: CpuId) -> *const T;
    fn get_mut_ptr_on_target(&mut self, cpu: CpuId) -> *mut T;
}

A trait to abstract any type that can be used as a slot for a CPU-local variable of type T.

Each slot provides the memory space for storing num_cpus instances of type T.

Safety

The implementor must ensure that the returned pointer refers to the variable on the correct CPU.

Required Methods

fn get_ptr_on_current(&self, guard: &DisabledLocalIrqGuard) -> *const T

Gets the const pointer for the object on the current CPU.

fn get_ptr_on_target(&self, cpu: CpuId) -> *const T

Gets the const pointer for the object on a target CPU.

fn get_mut_ptr_on_target(&mut self, cpu: CpuId) -> *mut T

Gets the mut pointer for the object on a target CPU.

This method is intended for use when initializing or dropping the storage.
