Function ywasm::encode_state_as_update

pub fn encode_state_as_update(
    doc: &mut YDoc, 
    vector: Option<Uint8Array>
) -> Uint8Array

Encodes all updates that have happened since a given version vector into a compact delta representation using lib0 v1 encoding. If vector parameter has not been provided, generated delta payload will contain all changes of a current ywasm document, working effectivelly as its state snapshot.

Example:

import {YDoc, encodeStateVector, encodeStateAsUpdate, applyUpdate} from 'ywasm'

/// document on machine A
const localDoc = new YDoc()
const localSV = encodeStateVector(localDoc)

// document on machine B
const remoteDoc = new YDoc()
const remoteDelta = encodeStateAsUpdate(remoteDoc, localSV)

applyUpdate(localDoc, remoteDelta)
