source · [−]

pub struct TaskManager {
    ready_queue: VecDeque<Arc<TaskControlBlock>>,
    stop_task: Option<Arc<TaskControlBlock>>,
}

Expand description

A array of TaskControlBlock that is thread-safe

Fields

ready_queue: VecDeque<Arc<TaskControlBlock>>stop_task: Option<Arc<TaskControlBlock>>

The stopping task, leave a reference so that the kernel stack will not be recycled when switching tasks
