InstallSnapshot

Struct InstallSnapshot 

Source
pub struct InstallSnapshot {
    pub term: Term,
    pub leader: NodeId,
    pub snapshot: Snapshot,
}
Expand description

A leader’s transfer of a Snapshot to a follower too far behind to replicate entry by entry.

When a follower’s next required entry has already been compacted out of the leader’s log, the leader sends this instead of an AppendEntries. The follower installs the snapshot — replacing its state through snapshot.index — then resumes normal replication from the tail.

§Examples

use raft_io::{InstallSnapshot, Snapshot};

let rpc = InstallSnapshot { term: 5, leader: 1, snapshot: Snapshot::new(10, 3, vec![]) };
assert_eq!(rpc.snapshot.index, 10);

Fields§

§term: Term

The leader’s term.

§leader: NodeId

The leader sending the snapshot.

§snapshot: Snapshot

The snapshot to install.
