Enum GossipPdu 

#[non_exhaustive]
pub enum GossipPdu {
    Status {
        from: String,
        version: VectorClock,
    },
    Envelope {
        from: String,
        version: VectorClock,
        state: MembershipState,
    },
    Merge {
        from: String,
        version: VectorClock,
    },
}

One gossip exchange. Sender hands a GossipStatus to the peer; peer responds with either a full GossipEnvelope (if it has newer state) or a GossipMerge request (if its state is older).

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.

Status

“Here is my version vector — do you have newer state?”

Fields

Envelope

“Here’s my whole state, merge it in.”

Fields

from: String

version: VectorClock

state: MembershipState

Merge

“I’m older than you — please send me your envelope.”

Fields

version: VectorClock
