Struct plumcast::message::MessageId

pub struct MessageId { /* fields omitted */ }

Message identifier.

An identifier consists of the node identifier part and the sequence number part. The node identifier part which type is NodeId indicates the sender (origin) of the message. The sequence number part indicates the number of messages broadcasted by the sender so far.

Identifiers are assigned automatically when broadcasting messages.

It is guaranteed that the identifiers are unique in a cluster unless the OS processes executing plumcast nodes are restarted. Practically confliction of identifiers is extremely rare even if OS processes are frequently restarted.

Methods

impl MessageId

pub fn node(&self) -> NodeId
