Piying

Fault-tolerant async actors built on Tokio.

Piying is a fork of Kameo by tqwewe.

Why fork?

• Larger production scope — Piying targets real-time networked games and other latency-sensitive distributed systems, driving changes to codec flexibility, networking, and error handling that go beyond upstream's focus.
• AI-generated code welcome — the upstream project does not accept AI-generated contributions. Piying has no such restriction.

Key differences from upstream

• Pluggable codec system (rkyv, serde, or custom) — decoupled from the core actor framework
• PiyingRkyvCodec for high-performance binary serialization via rkyv
• Various networking and swarm improvements for production P2P use

Upstream features (inherited)

• Lightweight async actors on Tokio
• Fault tolerance with supervision strategies
• Flexible messaging (bounded/unbounded channels, backpressure)
• Local and distributed communication via libp2p
• Panic safety and actor isolation
• Type-safe message interfaces
