Enum ControlPlaneRole 

pub enum ControlPlaneRole {
    Leader,
    Follower,
    Candidate,
}

This node’s role in the control-plane consensus layer.

Mirrors the Raft-equivalent roles. A node that holds data may take any role; a witness participates as a Follower or Candidate but never leads a data range — its leadership is over control-plane state only.

Variants

Leader

Currently leading the control-plane log; the normal writer of ownership catalog transitions (ADR 0037, ADR 0052).

Follower

Following the current leader; applies committed entries, votes per the durable last-vote rule.

Candidate

Standing in an election for a new term; not yet a leader.

Trait Implementations

impl Clone for ControlPlaneRole

fn clone(&self) -> ControlPlaneRole

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ControlPlaneRole

impl Debug for ControlPlaneRole

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

Formats the value using the given formatter.

impl Eq for ControlPlaneRole

impl PartialEq for ControlPlaneRole

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