Struct PreemptionSimulator 

pub struct PreemptionSimulator {
    pub time_slice: u64,
    pub ticks_used: u64,
    pub preemptions: u64,
    pub active_task: Option<TaskId>,
}

Simulates preemptive scheduling by tracking time slices.

Fields

time_slice: u64

Time slice in ticks per task before forced preemption.

ticks_used: u64

Current tick within the slice for the active task.

preemptions: u64

Total preemptions performed.

active_task: Option<TaskId>

Currently active task.

Implementations

impl PreemptionSimulator

pub fn new(time_slice: u64) -> Self

pub fn set_active(&mut self, id: TaskId)

Assign the active task.

pub fn tick(&mut self) -> bool

Tick the clock. Returns true if the task should be preempted.

pub fn remaining(&self) -> u64

Remaining ticks in the current slice.
