Read-only view of two beacon states.

Implement this trait to allow create to compute a BeaconStateDelta between two states.

Each method exposes the state component required by the corresponding delta encoder without imposing any storage layout on the implementation.

Dyn Compatibility

This trait is dyn compatible.

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