Struct RoundRobinScheduler 

pub struct RoundRobinScheduler { /* private fields */ }

Lock-free round-robin scheduler.

This scheduler maintains per-CPU run queues using lock-free ring buffers. Threads are scheduled in round-robin fashion with priority-based time slicing. Load balancing occurs when CPUs become idle or overloaded.

Implementations

impl RoundRobinScheduler

pub fn new(num_cpus: usize) -> Self

Create a new round-robin scheduler for the given number of CPUs.
