Enum ControlPlaneEntry 

pub enum ControlPlaneEntry {
    MembershipChange(ControlPlanePayload),
    OwnershipTransition(ControlPlanePayload),
}

A single entry in the control-plane log.

Closed over exactly the two control-plane concerns (see ControlPlaneEntryKind). There is no constructor for a user-data entry, so the data/control boundary cannot be crossed by appending to this log.

Variants

MembershipChange(ControlPlanePayload)

Admission, removal, or role change of a cluster member.

OwnershipTransition(ControlPlanePayload)

A fenced, versioned shard/range ownership catalog transition (ADR 0037), normally proposed by the Supervisor leader.

Implementations

impl ControlPlaneEntry

pub fn kind(&self) -> ControlPlaneEntryKind

The kind of this entry, without its payload.

pub fn payload(&self) -> &ControlPlanePayload

Borrow the entry’s opaque payload.

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<(), Error>

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.
