Enum zookeeper::KeeperState

pub enum KeeperState {
    Disconnected,
    SyncConnected,
    AuthFailed,
    ConnectedReadOnly,
    SaslAuthenticated,
    Expired,
}

Enumeration of states the client may be at a Watcher Event. It represents the state of the server at the time the event was generated.

Variants

Disconnected

The client is in the disconnected state - it is not connected to any server in the ensemble.

SyncConnected

The client is in the connected state - it is connected to a server in the ensemble (one of the servers specified in the host connection parameter during ZooKeeper client creation).

AuthFailed

Authentication has failed – connection requires a new ZooKeeper instance.

ConnectedReadOnly

The client is connected to a read-only server, that is the server which is not currently connected to the majority. The only operations allowed after receiving this state is read operations. This state is generated for read-only clients only since read/write clients aren’t allowed to connect to read-only servers.

SaslAuthenticated

Used to notify clients that they are SASL-authenticated, so that they can perform ZooKeeper actions with their SASL-authorized permissions.

Expired

The serving cluster has expired this session. The ZooKeeper client connection (the session) is no longer valid. You must create a new client connection (instantiate a new ZooKeeper instance) if you with to access the ensemble.

Trait Implementations

impl Clone for KeeperState

fn clone(&self) -> KeeperState

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for KeeperState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<i32> for KeeperState

fn from(val: i32) -> KeeperState

Converts to this type from the input type.

impl PartialEq<KeeperState> for KeeperState

fn eq(&self, other: &KeeperState) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
