Struct EventEnvelope 

pub struct EventEnvelope {
    pub event_name: EventName,
    pub event_id: String,
    pub app_id: AppId,
    pub node_id: NodeId,
    pub occurred_at_ms: u64,
    pub payload: Vec<u8>,
    pub trace: Option<TraceContext>,
}

Immutable event envelope.

Fields

event_name: EventName

Stable event name.

event_id: String

Unique event identity.

app_id: AppId

Application that emitted the event.

node_id: NodeId

Node that emitted the event.

occurred_at_ms: u64

Occurrence timestamp in Unix milliseconds.

payload: Vec<u8>

Opaque application-owned payload.

trace: Option<TraceContext>

Optional distributed trace context.
