Basic type for errors returned from the server.

Variants

APIError

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

Client authentication failed.

BadArguments

Invalid arguments.

BadVersion

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

Connection to the server has been lost.

DataInconsistency

A data inconsistency was found.

EphemeralOnLocalSession

Attempt to create ephemeral node on a local session.

InvalidACL

Invalid Acl specified.

InvalidCallback

Invalid callback specified.

MarshallingError

Error while marshalling or unmarshalling data.

NoAuth

Not authenticated.

NoChildrenForEphemerals

Ephemeral nodes may not have children.

NodeExists

Request to create node that already exists.

NoNode

Attempted to read a node that does not exist.

NotEmpty

The node has children.

NotReadOnly

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

NoWatcher

Attempt to remove a non-existing watcher.

OperationTimeout

Operation timeout.

RuntimeInconsistency

A runtime inconsistency was found.

SessionExpired

The session has been expired by the server.

SessionMoved

Session moved to another server, so operation is ignored.

SystemError

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

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)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

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
