Struct ProspectiveEvent 

pub struct ProspectiveEvent {
    pub id: String,
    pub stream: String,
    pub event_type: String,
    pub subject: Option<String>,
    pub data: Option<EventData>,
    pub time: Option<DateTime<Utc>>,
    pub datacontenttype: Option<String>,
    pub dataschema: Option<String>,
    pub extensions: Vec<(String, ExtensionValue)>,
}

A prospective event before storage.

In EvidentSource, prospective events use the stream name directly as the source. When stored, the server transforms this into a full URI in the Event type.

Fields

id: String

Unique identifier for this event (typically UUID).

stream: String

The stream this event belongs to. Maps to CloudEvents source.

event_type: String

The event type (e.g., “com.example.account.opened”).

subject: Option<String>

Optional subject identifying the entity this event is about.

data: Option<EventData>

Optional event data payload.

time: Option<DateTime<Utc>>

Optional timestamp when the event occurred.

datacontenttype: Option<String>

Optional content type of the data (e.g., “application/json”).

dataschema: Option<String>

Optional schema URI for the data.

extensions: Vec<(String, ExtensionValue)>

Extension attributes.
