impl PartialEq<u64> for LeaderId

fn eq(&self, _other: &u64) -> 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 PartialEq for LeaderId

fn eq(&self, other: &LeaderId) -> 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 PartialOrd<u64> for LeaderId

fn partial_cmp(&self, other: &u64) -> Option<Ordering>

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl PartialOrd for LeaderId

Implements PartialOrd for LeaderId to enforce the standard Raft behavior of at most one leader per term.

In standard Raft, each term can have at most one leader. This is enforced by making leader IDs with the same term incomparable (returning None), unless they refer to the same node.

This differs from the PartialOrd default implementation which would allow multiple leaders in the same term by comparing node IDs.

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl RaftLeaderId<TypeConfig> for LeaderId

type Committed = u64

The committed version of this leader ID.

fn new(term: u64, node_id: u64) -> Self

Create a new leader ID for the given term and node.

fn term(&self) -> u64

Get the term number of this leader

fn node_id(&self) -> &u64

Get the node ID of this leader

fn to_committed(&self) -> Self::Committed
