Struct raftlog::message::SequenceNumber

pub struct SequenceNumber(_);

メッセージのシーケンス番号.

この番号はノード毎に管理され、要求系のメッセージ送信の度にインクリメントされる. 応答系のメッセージでは、対応する要求メッセージのシーケンス番号が使用される.

シーケンス番号は、一つのTerm内では単調増加することが保証されている. 逆に言えば、複数のTermを跨いだ場合には、シーケンス番号が増加する保証は無い.

impl Ord for SequenceNumber

fn cmp(&self, other: &SequenceNumber) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

fn clamp(self, min: Self, max: Self) -> Self

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

Restrict a value to a certain interval.

impl PartialEq<SequenceNumber> for SequenceNumber

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

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

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

This method tests for !=.

impl PartialOrd<SequenceNumber> for SequenceNumber

fn partial_cmp(&self, other: &SequenceNumber) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &SequenceNumber) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &SequenceNumber) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &SequenceNumber) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &SequenceNumber) -> bool
