Processor management structure

## Fields

`current: Option<Arc<TaskControlBlock>>`

The task currently executing on the current processor

`idle_task_cx: TaskContext`

The basic control flow of each core, helping to select and switch process

## Implementations

source

### impl Processor

source

#### pub fn new() -> Self

source

#### fn get_idle_task_cx_ptr(&mut self) -> *mut TaskContext

Get mutable reference to `idle_task_cx`

source

#### pub fn take_current(&mut self) -> Option<Arc<TaskControlBlock>>

Get current task in moving semanteme

source

#### pub fn current(&self) -> Option<Arc<TaskControlBlock>>

Get current task in cloning semanteme
