Struct FailoverRequest 

pub struct FailoverRequest {
    pub old_primary: FailoverNode,
    pub target: FailoverNode,
    pub current_term: u64,
    pub target_frontier_hint: u64,
    pub mode: FailoverMode,
}

A request to hand the primary role from old_primary to target.

Fields

old_primary: FailoverNode

The node currently serving as primary.

target: FailoverNode

The replica being promoted.

current_term: u64

The replication term the cluster is serving now. The handover mints current_term + 1.

target_frontier_hint: u64

Last known acknowledged frontier of the target (from the replica registry). Lets the coordinator take a no-wait fast path when the target is already caught up at freeze time.

mode: FailoverMode

Coordinated vs. forced execution.

Implementations

impl FailoverRequest

pub fn new_term(&self) -> u64

The term the cluster serves after a successful handover.

Trait Implementations

impl Clone for FailoverRequest

fn clone(&self) -> FailoverRequest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FailoverRequest

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

Formats the value using the given formatter.

impl PartialEq for FailoverRequest

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