Struct RequestVote 

pub struct RequestVote {
    pub term: Term,
    pub candidate: NodeId,
    pub last_log_index: Index,
    pub last_log_term: Term,
    pub force: bool,
}

A candidate’s request for a vote in an election.

Sent by a Candidate to every peer when it starts an election. A recipient grants its vote only if it has not already voted in this term and the candidate’s log is at least as up to date as its own — the election restriction that keeps a node missing committed entries from becoming leader.

Examples

use raft_io::RequestVote;

let rv = RequestVote {
    term: 4, candidate: 2, last_log_index: 9, last_log_term: 3, force: false,
};
assert_eq!(rv.candidate, 2);

Fields

term: Term

The candidate’s term.

candidate: NodeId

The candidate requesting the vote.

last_log_index: Index

Index of the candidate’s last log entry.

last_log_term: Term

Term of the candidate’s last log entry.

force: bool

A forced election, requested by the current leader as part of a leadership transfer. A recipient honours it even within the leader-stickiness window, so the hand-off is not blocked by its own loyalty to the departing leader.

Trait Implementations

impl Clone for RequestVote

fn clone(&self) -> RequestVote

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RequestVote

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

Formats the value using the given formatter.

impl Deserialize for RequestVote

fn deserialize<__D: Decode + ?Sized>(__decoder: &mut __D) -> Result<Self>

Read a value of Self from the decoder, advancing its cursor.

fn deserialize_many<D>( decoder: &mut D, count: usize, ) -> Result<Vec<Self>, SerialError>

where D: Decode + ?Sized,

Read count consecutive Self values into a freshly-allocated Vec.

impl Eq for RequestVote

impl PartialEq for RequestVote

fn eq(&self, other: &RequestVote) -> 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.

impl Serialize for RequestVote

fn serialize<__E: Encode + ?Sized>(&self, __encoder: &mut __E) -> Result<()>

Append the encoded bytes of self to encoder.

fn serialize_slice<E>( slice: &[Self], encoder: &mut E, ) -> Result<(), SerialError>

where E: Encode + ?Sized, Self: Sized,

Append the encoded bytes of every element of slice to encoder.
