Game-agnostic realtime sync runtime for server-authoritative multiplayer over WebSockets.

What it provides

• Fixed-timestep runtime (default 60 Hz)
• Session manager for start/stop and per-session input ingestion
• Per-player input coalescing via MergeInput
• Snapshot and game-event stream per session
• Optional WebSocket codec crate with MessagePack support

Workspace crates

• crates/realtime-sync-core: runtime traits and session loop
• crates/realtime-sync-ws: codec utilities for WS payloads
• examples/minimal-2d: minimal game model integration example

Quick start

cargo test --all-targets --all-features
cargo clippy --all-targets --all-features -- -D warnings
cargo run -p minimal-2d

Integration model

1. Implement GameModel for your game state.
2. Implement MergeInput for your input type.
3. Start sessions through Runtime::::start_session.
4. Forward client input into SessionHandle::submit_input.
5. Stream RuntimeEvent::Snapshot and RuntimeEvent::GameEvent to clients.
