Enum RequiredConsumerError 

pub enum RequiredConsumerError {
    StartupTimeout {
        missing: Vec<String>,
    },
    GracefulShutdownTriggered {
        consumer_id: String,
        last_sequence: Sequence,
        stalled_for: Duration,
    },
}

Producer-visible failure when required-consumer liveness cannot be maintained.

Variants

StartupTimeout

One or more required consumers never appeared during producer startup.

Fields

missing: Vec<String>

Required consumer IDs that never appeared before startup timed out.

GracefulShutdownTriggered

A required consumer stopped advancing long enough that the producer shut the topology down.

Fields

consumer_id: String

Required consumer ID that stopped advancing.

last_sequence: Sequence

Last observed committed sequence for the stalled consumer.

stalled_for: Duration

Total time since the stalled consumer last advanced.

Trait Implementations

impl Clone for RequiredConsumerError

fn clone(&self) -> RequiredConsumerError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RequiredConsumerError

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

Formats the value using the given formatter.

impl Display for RequiredConsumerError

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

Formats the value using the given formatter.

impl Error for RequiredConsumerError

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.
