There are not exposed parts that block decoding binary messages from other parts of application.
With those two exports it's possible with following code

import * as Y from "yjs"
import * as decoding from "lib0/decoding"
const doc = Y.Doc()
doc.on("update", (e) => {
	const structs = []
	const updateDecoder = new Y.UpdateDecoderV1(decoding.createDecoder(e))
	const lazyDecoder = new Y.LazyDecoder(updateDecoder)
	for (let curr = lazyDecoder.curr; curr !== null; curr = lazyDecoder.next()) {
		structs.push(curr)
	}
	const deleteSet = Y.readDeleteSet(updateDecoder)
	console.log(structs, deleteSet)
})
