Struct rstubs::threading::sleep::BellRinger

source ·
pub struct BellRinger {
    bells: ArrayDeque<Bell, APPS>,
}
Expand description

Manages and activates time-triggered activities.

The Bellringer is regularly activated and checks whether any of the bells should ring. The bells are stored in a queue that is managed by the Bellringer. A clever implementation avoids iterating through the whole list for every iteration by keeping the bells sorted and storing delta times. This approach leads to a complexity of O(1) for the method called by the timer interrupt in case no bells need to be rung.

§bells: ArrayDeque<Bell, APPS>

Implementations§

source§

impl BellRinger

source

pub const fn new() -> Self

source

pub fn sleep(&mut self, scheduler: &mut Scheduler, ms: usize)

Blocks the current thread for the number of milliseconds

Tip regarding the borrow checker:

let g = &mut *GUARD.enter(); // borrow here, to get mutable references to different fields
g.bell_ringer.sleep(&mut g.scheduler, *dur as _);
source

pub fn check(&mut self, scheduler: &mut Scheduler)

Wakes up waiting threads

source

pub fn is_empty(&self) -> bool
