Enum ZkState

pub enum ZkState {
    Associating,
    AuthFailed,
    Closed,
    Connected,
    ConnectedReadOnly,
    Connecting,
    NotConnected,
}

Enumeration of states the client may be at any time.

Variants

Associating

👎Deprecated

Previously used to represent a state between connection (as in connected to a server) and authenticated. This is no longer used.

AuthFailed

Authentication has failed. Operations will return ZkError::AuthFailed.

Closed

The session has ended. Operations will return ZkError::SessionExpired.

Connected

Session has been fully established. Operations will proceed as normal.

ConnectedReadOnly

Connected to a read-only server. See KeeperState::ConnectedReadOnly.

Connecting

Currently attempting to connect with an ensemble member. Operations are queued until a session is established.

NotConnected

👎Deprecated

Theoretically used as a special state to represent ZkError::ConnectionLoss for expected reasons (ensemble reconfiguration), but Closed has proven less error-prone. This is no longer used.

Trait Implementations

impl Clone for ZkState

fn clone(&self) -> ZkState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ZkState

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

Formats the value using the given formatter.

impl Display for ZkState

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

Formats the value using the given formatter.

impl From<ZkState> for String

fn from(value: ZkState) -> Self

Converts to this type from the input type.

impl PartialEq for ZkState

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

Tests for self and other values to be equal, and is used by ==.

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

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