Struct AppendEntriesRequest 

pub struct AppendEntriesRequest {
    pub term: Term,
    pub leader_id: NodeId,
    pub prev_log_index: LogIndex,
    pub prev_log_term: Term,
    pub entries: Vec<LogEntry>,
    pub leader_commit: LogIndex,
    pub fencing_token: Option<FencingToken>,
}

Request to append entries (heartbeat or log replication)

Fields

term: Term

Leader’s term

leader_id: NodeId

Leader’s ID (for redirecting clients)

prev_log_index: LogIndex

Index of log entry immediately preceding new ones

prev_log_term: Term

Term of prev_log_index entry

entries: Vec<LogEntry>

Log entries to store (empty for heartbeat)

leader_commit: LogIndex

Leader’s commit index

fencing_token: Option<FencingToken>

Optional fencing token issued by the leader (None for legacy / non-leaders)

Implementations

impl AppendEntriesRequest

pub fn new( term: Term, leader_id: NodeId, prev_log_index: LogIndex, prev_log_term: Term, entries: Vec<LogEntry>, leader_commit: LogIndex, ) -> Self

Create a new append entries request

pub fn with_fencing_token( term: Term, leader_id: NodeId, prev_log_index: LogIndex, prev_log_term: Term, entries: Vec<LogEntry>, leader_commit: LogIndex, token: FencingToken, ) -> Self

Create an append entries request with a fencing token attached

pub fn heartbeat( term: Term, leader_id: NodeId, prev_log_index: LogIndex, prev_log_term: Term, leader_commit: LogIndex, ) -> Self

Create a heartbeat (empty entries)

pub fn is_heartbeat(&self) -> bool

Check if this is a heartbeat (no entries)

Trait Implementations

impl Clone for AppendEntriesRequest

fn clone(&self) -> AppendEntriesRequest

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AppendEntriesRequest

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

Formats the value using the given formatter.

impl PartialEq for AppendEntriesRequest

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
