Enum KeeperState

#[repr(i32)]
pub enum KeeperState {
    Disconnected = 0,
    SyncConnected = 3,
    AuthFailed = 4,
    ConnectedReadOnly = 5,
    SaslAuthenticated = 6,
    Expired = -112,
}

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 = 0

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

SyncConnected = 3

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 = 4

Authentication has failed – connection requires a new ZooKeeper instance.

ConnectedReadOnly = 5

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 = 6

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

Expired = -112

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 The ZooKeeper client connection (the session) is no longer valid.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 duplicate 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 Display for KeeperState

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

Formats the value using the given formatter.

impl From<KeeperState> for String

fn from(value: KeeperState) -> Self

Converts to this type from the input type.

impl Hash for KeeperState

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for KeeperState

fn cmp(&self, other: &KeeperState) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for KeeperState

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

fn partial_cmp(&self, other: &KeeperState) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

fn try_from(number: i32) -> Result<Self, TryFromPrimitiveError<Self>>

Performs the conversion.

impl TryFromPrimitive for KeeperState

const NAME: &'static str = "KeeperState"

type Primitive = i32
