Enum HaltPdu 

#[non_exhaustive]
pub enum HaltPdu {
    Halt {
        from: String,
        epoch: u64,
        reason: HaltReason,
    },
    Ack {
        from: String,
        epoch: u64,
    },
}

Wire shape of a cross-node kill-switch exchange. Mirrors the MediatorPdu pattern used by ClusterPubSub: an opaque, serializable message that a HaltTransport carries to a peer and that the peer feeds back via ClusterKillSwitch::apply_pdu.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Halt

Ask the receiving node to engage its latch for epoch, bring its local guarded parties to a safe stop, and ack. Carries the originator’s node id and the engaging HaltReason so the remote audit trail matches the coordinator’s.

Fields

from: String

epoch: u64

reason: HaltReason

Ack

Acknowledge that from has quiesced its local parties for epoch.

Fields

from: String

epoch: u64

Trait Implementations

impl Clone for HaltPdu

fn clone(&self) -> HaltPdu

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HaltPdu

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

Formats the value using the given formatter.

impl PartialEq for HaltPdu

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