Enum MetaError 

pub enum MetaError {
    Consensus(ConsensusError),
    Encode(String),
    Rejected(MetaRejectionReason),
    InvalidRequest(String),
    Io(Error),
    Rng(String),
    CorruptCheckpoint(String),
}

Errors of the meta control-plane surface (group factory, membership workflow, proposals).

Variants

Consensus(ConsensusError)

Consensus group failure (including the routed ConsensusError::NotLeader leader hint, spec section 11.7).

Encode(String)

Encoding a MetaCommandRecord failed.

Rejected(MetaRejectionReason)

The command committed but the apply path refused it; the typed reason is also journaled in MetaState::rejections.

InvalidRequest(String)

The caller’s request was malformed for this group (raft-id projection collision, mismatched group config, invalid workflow order).

Io(Error)

Meta group I/O failure.

Rng(String)

The caller-supplied operating-system CSPRNG failed.

CorruptCheckpoint(String)

The sink’s durable checkpoint failed verification (fails closed, spec section 4.10).

Trait Implementations

impl Debug for MetaError

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

Formats the value using the given formatter.

impl Display for MetaError

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

Formats the value using the given formatter.

impl Error for MetaError

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<Error> for MetaError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<MetaError> for RuntimeError

fn from(source: MetaError) -> Self
