Trait GameState 

pub trait GameState:
    Clone
    + Send
    + 'static {
    // Required methods
    fn advance(&mut self, inputs: &FrameInput);
    fn checksum(&self) -> u64;

    // Provided method
    fn snapshot_size_hint() -> usize { ... }
}

Implement this on your game state to enable rollback.

Required Methods

fn advance(&mut self, inputs: &FrameInput)

Advance simulation by one frame using the given inputs.

fn checksum(&self) -> u64

Compute a checksum of the game state (for desync detection).

Provided Methods

fn snapshot_size_hint() -> usize

Memory size hint for the snapshot (used for buffer sizing).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
