Struct Event 

pub struct Event {
    pub id: String,
    pub topic: String,
    pub source: String,
    pub payload: String,
    pub privacy_boundary: String,
    pub timestamp_ms: u64,
    pub correlation_id: Option<String>,
}

A message on the bus. Agents produce and consume these.

Fields

id: String

Unique event identifier.

topic: String

Topic string for pub/sub routing (e.g. “task.image.complete”).

source: String

Who published this event (agent_id, channel name, or “system”).

payload: String

Event payload — typically JSON, but can be any string.

privacy_boundary: String

Privacy boundary inherited from the source (e.g. “local_only”, “any”).

timestamp_ms: u64

Unix timestamp in milliseconds.

correlation_id: Option<String>

Traces a chain of events back to the original trigger. All events in an agent chain share the same correlation_id.

Implementations

impl Event

pub fn new( topic: impl Into<String>, source: impl Into<String>, payload: impl Into<String>, ) -> Self

Create a new event with a generated id and current timestamp.

pub fn with_correlation(self, id: impl Into<String>) -> Self

Set the correlation id (builder pattern).

pub fn with_boundary(self, boundary: impl Into<String>) -> Self

Set the privacy boundary (builder pattern).

Trait Implementations
