A Rust library providing a family of well-tested, serializable CRDTs (Conflict-free Replicated Data Types) supporting both state-based (CvRDT) and op-based (CmRDT) replication. It enables building highly available distributed systems where replicas can merge state without conflicts.

Use cases

• build a distributed database with conflict-free replication
• sync collaborative app state across offline peers
• implement eventually consistent counters, sets, and maps in Rust
• replicate mutable state between nodes without a central coordinator
• merge concurrent edits in a peer-to-peer application

When to choose

• you need conflict-free replicated data structures in Rust
• you want both state-based and op-based replication support
• you need thoroughly tested, serializable CRDT primitives like GCounter, LWWRegister, or ORSet

When to avoid

• you need a full distributed database or sync service rather than data structure primitives
• your project is not in Rust
• you need real-time collaborative text editing with rich operational transforms
