Struct LogId 

pub struct LogId<NID>
where
    NID: NodeId,
{
    pub leader_id: LeaderId<NID>,
    pub index: u64,
}

The identity of a raft log.

The log id serves as unique identifier for a log entry across the system. It is composed of two parts: a leader id, which refers to the leader that proposed this log, and an integer index.

Fields

leader_id: LeaderId<NID>

The id of the leader that proposed this log

index: u64

The index of a log in the storage.

Log index is a consecutive integer.

Implementations

impl<NID> LogId<NID>

where NID: NodeId,

pub fn new(leader_id: LeaderId<NID>, index: u64) -> LogId<NID>

Creates a log id proposed by a committed leader with leader_id at the given index.

pub fn committed_leader_id(&self) -> &LeaderId<NID>

Returns the leader id that proposed this log.

Trait Implementations

impl<NID> Ord for LogId<NID>

where NID: Ord + NodeId,

fn cmp(&self, other: &LogId<NID>) -> Ordering

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.
