Trait RestartStateComponent 

pub trait RestartStateComponent<CaptureCtx, RestoreCtx, Command, Digest> {
    type Snapshot;

    const NAME: RestartComponentName;

    // Required methods
    fn capture(ctx: &CaptureCtx) -> Self::Snapshot;
    fn restore(ctx: &mut RestoreCtx, snapshot: &Self::Snapshot);
    fn digest(ctx: &CaptureCtx) -> Digest;
    fn replay(command: &Command, ctx: &mut RestoreCtx) -> ReplayDisposition;
    fn mutation_sources() -> &'static [MutationSource];

    // Provided method
    fn descriptor() -> RestartComponentDescriptor { ... }
}

Contract every restart-owned component must implement.

The concrete engine state and command types still live outside this crate. Capture and restore contexts are intentionally separate because snapshot capture often needs a durable boundary while restore mutates engine state.

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.
