The base error type for raft

Variants

Io(Error)

An IO error occurred

Store(StorageError)

A storage error occurred.

StepLocalMsg

Raft cannot step the local message.

StepPeerNotFound

The raft peer is not found and thus cannot step.

ProposalDropped

The proposal of changes was dropped.

ConfigInvalid(String)

The configuration is invalid.

CodecError(ProtobufError)

A protobuf message codec failed in some manner.

Exists

The node exists, but should not.

Fields of Exists

id: u64

The node id.

set: &'static str

The node set.

NotExists

The node does not exist, but should.

Fields of NotExists

id: u64

The node id.

set: &'static str

The node set.

ConfChangeError(String)

ConfChange proposal is invalid.

RequestSnapshotDropped

The request snapshot is dropped.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<Error> for Error

fn from(source: Error) -> Self

Performs the conversion.

impl From<ProtobufError> for Error

fn from(source: ProtobufError) -> Self

Performs the conversion.

impl From<StorageError> for Error

fn from(source: StorageError) -> Self

Performs the conversion.

impl PartialEq<Error> for Error

fn eq(&self, other: &Error) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]pub fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
