Rust implementation of automerge

Automerge

This is a very early, very much work in progress implementation of automerge in rust. At the moment it barely implements a read only view of operations received, with very little testing that it works. Objectives for it are:

• Full read and write replication
• no_std support to make it easy to use in WASM environments
• Model based testing to ensure compatibility with the JS library

How to use

Add this to your dependencies

automerge = 0.0.2

You'll need to export changes from automerge as JSON rather than using the encoding that Automerge.save uses. So first do this:

const doc = <your automerge document>
const changes = Automerge.getHistory(doc).map(h => h.change)
console.log(JSON.stringify(changes, null, 4))

Now you can load these changes into automerge like so:

extern crate automerge;

fn main() {
    let changes: Vec<automerge::Change> = serde_json::from_str("<paste the changes JSON here>").unwrap();
    let document = automerge::Document::load(changes).unwrap();
    let state: serde_json::Value = document.state().unwrap();
    println!("{:?}", state);
}
