Enum ControlPlaneEntry 

pub enum ControlPlaneEntry {
    MembershipChange(MembershipChange),
    OwnershipTransition(OwnershipTransition),
    LeaderConfiguration {
        term: ControlPlaneTerm,
        leader: ClusterVoterIdentity,
    },
}

The complete, closed set of things that may be appended to the Cluster Supervisor control-plane log.

There is no user-data variant on purpose. The absence is the enforcement mechanism for the central decision (ADR 0052): durable user writes cannot be expressed as a control-plane entry, so they cannot be routed through, gated by, or made to wait on Supervisor consensus. Adding a user-payload variant here would be a decision reversal and must go through a new ADR, not a code change.

Variants

MembershipChange(MembershipChange)

A member admitted to or removed from the cluster.

OwnershipTransition(OwnershipTransition)

A fenced, versioned shard/range ownership-catalog transition — the Supervisor leader’s normal write.

LeaderConfiguration

A record that term elected leader, keeping the elected-term history durable alongside the entries that term produced.

Fields

term: ControlPlaneTerm

The Supervisor term that elected the leader.

leader: ClusterVoterIdentity

The member elected leader for term.

Trait Implementations

impl Clone for ControlPlaneEntry

fn clone(&self) -> ControlPlaneEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ControlPlaneEntry

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

Formats the value using the given formatter.

impl Eq for ControlPlaneEntry

impl PartialEq for ControlPlaneEntry

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