Enum QuorumError 

pub enum QuorumError {
    Timeout {
        target_lsn: u64,
        elapsed_ms: u128,
        acked_regions: HashSet<String>,
    },
    InsufficientReplicas {
        required: usize,
        connected: usize,
    },
    MissingRegions {
        missing: Vec<String>,
    },
}

Errors raised by the quorum coordinator. The write itself succeeded on the primary WAL — these errors signal that replica acknowledgement did not reach quorum and the caller must decide whether to surface the failure or continue anyway.

Variants

Timeout

Timed out waiting for enough acks. Includes the set of regions that had replied (for observability / fallback routing).

Fields

target_lsn: u64

elapsed_ms: u128

acked_regions: HashSet<String>

InsufficientReplicas

Not enough replicas are currently connected to ever satisfy the configured quorum. Returned immediately (no wait) so the caller can fail fast instead of hanging on a timeout.

Fields

required: usize

connected: usize

MissingRegions

Required-regions mode is configured but one or more regions have zero connected replicas. Reported up front so the health-check layer can alert on “regional partition” before writes stall.

Fields

missing: Vec<String>

Trait Implementations

impl Clone for QuorumError

fn clone(&self) -> QuorumError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QuorumError

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

Formats the value using the given formatter.

impl Display for QuorumError

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

Formats the value using the given formatter.

impl Error for QuorumError

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.
