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.

Codec(ProtobufError)

A Protobuf message failed in some manner.

Exists(u64, &'static str)

The node exists, but should not.

NotExists(u64, &'static str)

The node does not exist, but should.

InvalidState(StateRole)

The action given requires the node to be in a particular state role.

NoPendingMembershipChange

The node attempted to transition to a new membership configuration while there was none pending.

ViolatesContract(String)

An argument violates a calling contract.

impl Error for Error

fn description(&self) -> &str

This method is soft-deprecated.

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

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
