Implementing a distributed lock via Zenoh

[hassomehide]

Zenoh provides some very nice high level abstractions for working with distributed systems. One such abstraction that is missing, however, is distributed locks. I would assume that Zenoh already implements some kind of distributed locking internally - if so, is there any plan to make it a publicly available feature via the client libraries? And if not, how would one implement a distributed lock using the existing primitives?

For instance, imagine this kotlin pseudocode which I adapted from java.util.concurrent.locks.Lock#tryLock():

val session: Session = Zenoh.open(Config.default()).getOrThrow()
val keyExpr: KeyExpr = "example/123/lock".intoKeyExpr().getOrThrow()
val lock: ZLock = session.declareLock(keyExpr)
if (lock.tryLock(10, SECONDS)) {
    try {
        // only one peer in the network should be able to reach this
    } finally {
        lock.unlock()
    }
} else {
    // perform alternative actions
}
