Trait WaitStrategy 

pub trait WaitStrategy {
    // Required methods
    fn reset(&mut self);
    fn wait(&mut self);
}

Progressive backoff when polling.

This trait is intentionally minimal and no_std-friendly. It is typically used at the edges (router loops, receive loops) to avoid busy-spinning.

Contract

• Implementations should be cheap and panic-free.
• wait may spin, yield, or sleep depending on the strategy.
• Callers should treat wait as a hint; it does not guarantee that the observed condition will change.

Required Methods

fn reset(&mut self)

Reset internal counters to the initial (most aggressive) state.

fn wait(&mut self)

Perform one backoff step (spin/yield/sleep depending on implementation).
