Enum openraft::raft::AppendEntriesResponse

pub enum AppendEntriesResponse<NID: NodeId> {
    Success,
    PartialSuccess(Option<LogId<NID>>),
    Conflict,
    HigherVote(Vote<NID>),
}

The response to an AppendEntriesRequest.

RaftNetwork::append_entries returns this type only when received an RPC reply. Otherwise it should return RPCError.

Variants

Success

Successfully replicated all log entries to the target node.

PartialSuccess(Option<LogId<NID>>)

Successfully sent the first portion of log entries.

RaftNetwork::append_entries can return a partial success. For example, it tries to send log entries [1-2..3-10], the application is allowed to send just [1-2..1-3] and return PartialSuccess(1-3),

Caution

The returned matching log id must be greater than or equal to the first log id(AppendEntriesRequest::prev_log_id) of the entries to send. If no RPC reply is received, RaftNetwork::append_entries must return an RPCError to inform Openraft that the first log id(AppendEntriesRequest::prev_log_id) may not match on the remote target node.

Conflict

The first log id(AppendEntriesRequest::prev_log_id) of the entries to send does not match on the remote target node.

HigherVote(Vote<NID>)

Seen a vote v that does not hold mine_vote >= v. And a leader’s vote(committed vote) must be total order with other vote. Therefore it has to be a higher vote: mine_vote < v
