Enum LogError 

pub enum LogError {
    Envelope(EnvelopeError),
    Cancelled,
    DeadlineExceeded,
    Closed,
    NotLeader {
        leader_hint: Option<String>,
    },
    Unsupported(&'static str),
    Internal(String),
}

Errors produced by a CommitLog.

Variants

Envelope(EnvelopeError)

The command envelope was malformed or unverifiable.

Cancelled

The operation was cancelled.

DeadlineExceeded

The operation’s deadline expired.

Closed

The log is closed and rejects new proposals.

NotLeader

The receiving replica is not the leader for the consensus group (spec section 11.7). Retryable with the returned leader hint.

Category mapping: this variant carries mongreldb_types::errors::ErrorCategory::NotLeader semantics. No LogError → ErrorCategory bridge exists yet (the engine commit path does not convert LogError today); the bridge lands with the Stage 2G gateway/routing wave, which consumes the hint.

Fields

leader_hint: Option<String>

The group’s current leader hint when known (text form of the leader identity, e.g. its raft node id); None when the group has no known leader.

Unsupported(&'static str)

The implementation does not provide this operation.

Internal(String)

Any other log failure.

Trait Implementations

impl Debug for LogError

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

Formats the value using the given formatter.

impl Display for LogError

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

Formats the value using the given formatter.

impl Error for LogError

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<EnvelopeError> for LogError

fn from(source: EnvelopeError) -> Self

Converts to this type from the input type.
