Errors surfaced by the streams membership client.

Variants

Transport(ClientError)

A transport failure or a dispatch failure from krabka-client-core.

Topology(TopologyError)

The topology build failed, because the node graph is bad.

CoordinatorUnavailable

The group coordinator was unavailable past the retry deadline.

InvalidTopology

The broker rejected the topology with an error from the STREAMS_INVALID_TOPOLOGY* family.

Fields

code: i16

message: String

Authorization(i16)

GROUP_AUTHORIZATION_FAILED / TOPIC_AUTHORIZATION_FAILED.

GroupIdNotFound

GROUP_ID_NOT_FOUND.

Closed

The membership handle has been closed.

Server(i16)

An unmapped broker error code.

Runtime(String)

A runtime failure in processing, produce, or commit.

Producer(ProducerError)

The transactional or idempotent producer was fenced by a newer epoch. This is fatal for the stream thread and must never enter retry rollback.

InteractiveQuery(IqError)

An interactive query failed.

BarrierFormat

A record on the __barrier_state topic does not match the frozen layout. part names the record part that failed, either key or cut value.

Fields

part: &'static str

message: String

Snapshot(String)

A state-store snapshot could not be written, read, or decoded.

Trait Implementations

impl Debug for StreamsClientError

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

Formats the value using the given formatter.

impl Display for StreamsClientError

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

Formats the value using the given formatter.

impl Error for StreamsClientError

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.
