Enum CreateMode

pub enum CreateMode {
    Persistent = 0,
    Ephemeral = 1,
    PersistentSequential = 2,
    EphemeralSequential = 3,
    Container = 4,
    PersistentWithTTL = 5,
    PersistentSequentialWithTTL = 6,
}

CreateMode value determines how the znode is created on ZooKeeper.

Variants

Persistent = 0

The znode will not be automatically deleted upon client’s disconnect.

Ephemeral = 1

The znode will be deleted upon the client’s disconnect.

PersistentSequential = 2

The name of the znode will be appended with a monotonically increasing number. The actual path name of a sequential node will be the given path plus a suffix "i" where i is the current sequential number of the node. The sequence number is always fixed length of 10 digits, 0 padded. Once such a node is created, the sequential number will be incremented by one.

EphemeralSequential = 3

The znode will be deleted upon the client’s disconnect, and its name will be appended with a monotonically increasing number.

Container = 4

Container nodes are special purpose nodes useful for recipes such as leader, lock, etc. When the last child of a container is deleted, the container becomes a candidate to be deleted by the server at some point in the future. Given this property, you should be prepared to get ZkError::NoNode when creating children inside of this container node.

PersistentWithTTL = 5

The znode will not be automatically deleted upon client’s disconnect, but it will be deleted if it has not been modified within the given TTL and has no children.

PersistentSequentialWithTTL = 6

The same as PersistentSequential, but the znode will be deleted if it has not been modified within the given TTL and has no children.

Implementations

impl CreateMode

pub fn is_sequential(&self) -> bool

Returns true if the CreateMode is one of the sequential types.

pub fn is_ttl(&self) -> bool

Returns true if the CreateMode is one of the TTL types.

Trait Implementations

impl Clone for CreateMode

fn clone(&self) -> CreateMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CreateMode

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

Formats the value using the given formatter.

impl Display for CreateMode

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

Formats the value using the given formatter.

impl From<CreateMode> for String

fn from(value: CreateMode) -> Self

Converts to this type from the input type.

impl Hash for CreateMode

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 CreateMode

fn cmp(&self, other: &CreateMode) -> 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 CreateMode

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

impl PartialOrd for CreateMode

fn partial_cmp(&self, other: &CreateMode) -> 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.
