Trait DeterministicReplay 

pub trait DeterministicReplay: DemoEngine {
    // Required method
    fn state_checksum(&self) -> u64;

    // Provided method
    fn verify_determinism(&self, other: &Self) -> bool { ... }
}

Helper trait for demos that support deterministic replay.

Per Lavoie & Hendren (2015): Given identical configuration and seed, two independent runs must produce bit-identical state sequences.

Required Methods

fn state_checksum(&self) -> u64

Get a checksum of the current state for quick comparison.

Provided Methods

fn verify_determinism(&self, other: &Self) -> bool

Verify that two runs with same config produce identical results.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
