Module bern_kernel::task

Task creation and control.

Example

Create a task using the builder pattern:

let mut heartbeat = board.shield.led_1;
Task::new()
    .priority(Priority(0))
    .static_stack(kernel::alloc_static_stack!(512))
    .spawn(move || {
        loop {
            kernel::sleep(200);
            heartbeat.toggle().ok();
        }
    });

The task builder (TaskBuilder) is used to configure a task. On TaskBuilder::spawn() the information is passed to the scheduler and the task is put into ready state.

Tasks can be spawened from main() or within other tasks.
