Perform a CAS operation on the key, only if the value has not changed since the value was last retrieved, and casUnique extracted from a gets command.
Perform a CAS operation on the key, only if the value has not changed since the value was last retrieved, and casUnique extracted from a gets command. We treat the "cas unique" token opaquely, but in reality it is a string-encoded u64.

Stored if the operation was successful, Exists if the operation failed because someone else had changed the value, or NotFound if the key was not found in the cache.

def checkAndSet(key: String, value: Buf, casUnique: Buf): Future[CasResult]

Perform a CAS operation on the key, only if the value has not changed since the value was last retrieved.
Perform a CAS operation on the key, only if the value has not changed since the value was last retrieved. This is enforced by passing a casUnique token extracted from a gets command. If the casUnique token matches the one on the server, the value is replaced. We treat the "cas unique" token opaquely, but in reality it is a string-encoded u64.
returns
Stored if the operation was successful, Exists if the operation failed because someone else had changed the value, or NotFound if the key was not found in the cache.
