}

Basic type for errors returned from the server.

Variants

APIError = -100

This code is never returned from the server. It should not be used other than to indicate a range. Specifically error codes greater than this value are API errors (while values less than this indicate a system error).

AuthFailed = -115

Client authentication failed.

BadArguments = -8

Invalid arguments.

BadVersion = -103

Version conflict in set operation. In case of reconfiguration: reconfig requested from config version X but last seen config has a different version Y.

ConnectionLoss = -4

Connection to the server has been lost.

DataInconsistency = -3

A data inconsistency was found.

EphemeralOnLocalSession = -120

Attempt to create ephemeral node on a local session.

InvalidACL = -114

Invalid Acl specified.

InvalidCallback = -113

Invalid callback specified.

MarshallingError = -5

Error while marshalling or unmarshalling data.

NoAuth = -102

Not authenticated.

NoChildrenForEphemerals = -108

Ephemeral nodes may not have children.

NodeExists = -110

Request to create node that already exists.

NoNode = -101

Attempted to read a node that does not exist.

NotEmpty = -111

The node has children.

NotReadOnly = -119

State-changing request is passed to read-only server.

NoWatcher = -121

Attempt to remove a non-existing watcher.

OperationTimeout = -7

Operation timeout.

RuntimeInconsistency = -2

A runtime inconsistency was found.

SessionExpired = -112

The session has been expired by the server.

SessionMoved = -118

Session moved to another server, so operation is ignored.

SystemError = -1

System and server-side errors. This is never thrown by the server, it shouldn’t be used other than to indicate a range. Specifically error codes greater than this value, but lesser than APIError, are system errors.

Unimplemented = -6

Operation is unimplemented.

Trait Implementations

impl Clone for ZkError

fn clone(&self) -> ZkError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ZkError

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

Formats the value using the given formatter.

impl Display for ZkError

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

Formats the value using the given formatter.

impl Error for ZkError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<ZkError> for String

fn from(value: ZkError) -> Self

Converts to this type from the input type.

impl From<i32> for ZkError

fn from(number: i32) -> Self

Converts to this type from the input type.

impl FromPrimitive for ZkError

type Primitive = i32

fn from_primitive(number: Self::Primitive) -> Self

impl Hash for ZkError

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 ZkError

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

fn eq(&self, other: &ZkError) -> 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 ZkError

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