Struct SingleNodeControlPlane 

pub struct SingleNodeControlPlane { /* private fields */ }

A minimal single-node control-plane engine: this node is the sole voter and therefore the leader of term 1. It exists to (a) give the first cut a usable implementation of the boundary, and (b) make the leader-only-append and no-user-data invariants executable tests rather than prose.

It is intentionally not the replicated engine — that is a later slice. What matters is that the later engine swaps in behind ControlPlaneConsensus without touching callers.

Implementations

impl SingleNodeControlPlane

pub fn bootstrap_leader(identity: ClusterVoterIdentity) -> Self

A single-node control plane that has elected identity as the leader of term 1, voting for itself. This is the trivial-but-correct quorum: a one-member majority.

pub fn entries(&self) -> &[ControlPlaneEntry]

The entries committed so far, in log order.

Trait Implementations

impl ControlPlaneConsensus for SingleNodeControlPlane

fn current_term(&self) -> ControlPlaneTerm

The current Supervisor election term.

fn leader(&self) -> Option<ClusterVoterIdentity>

The current Supervisor leader, if one is elected for current_term.

fn is_leader(&self) -> bool

Is this node the current Supervisor leader?

fn durable_vote(&self) -> DurableVoteState

The durable per-node vote state, persisted before acknowledging a vote.

fn commit_index(&self) -> Option<ControlPlaneIndex>

The index of the highest committed entry, or None if the log is empty.

fn append( &mut self, entry: ControlPlaneEntry, ) -> Result<ControlPlaneIndex, ControlPlaneError>

Append a control-plane entry as the leader.

impl Debug for SingleNodeControlPlane

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

Formats the value using the given formatter.
