# Piying
 [](flake.nix) [](https://crates.io/crates/piying)
Fault-tolerant async actors built on Tokio.
**Piying** is a fork of [Kameo](https://github.com/tqwewe/kameo) by [tqwewe](https://github.com/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
