Y CRDT
A collection of Rust libraries oriented around implementing Yjs algorithm and protocol with cross-language and cross-platform support in mind. It aims to maintain behavior and binary protocol compatibility with Yjs, therefore projects using Yjs/Yrs should be able to interoperate with each other.
Project organization:
- lib0 is a serialization library used for efficient (and fairly fast) data exchange.
- yrs (read: wires) is a core Rust library, a foundation stone for other projects.
- yffi (read: wifi) is a wrapper around yrs use to provide a native C foreign function interface. See also: C header file.
- ywasm is a wrapper around yrs that targets Web Assembly and JavaScript API.
Other projects using yrs:
