Struct event_store_core::event::UnsavedEvent

pub struct UnsavedEvent {
    pub causation_id: Option<Uuid>,
    pub correlation_id: Option<Uuid>,
    pub event_type: String,
    pub data: Value,
    pub metadata: Value,
    pub event_uuid: Uuid,
    pub stream_uuid: String,
    pub stream_version: u64,
    pub created_at: DateTime<Utc>,
}

An UnsavedEvent is created from a type that implement Event

This kind of event represents an unsaved event, meaning that it has less informations than a RecordedEvent. It’s a generic form to simplify the event processing but also a way to define metadata, causation_id and correlation_id.

Fields

causation_id: Option<Uuid>

a causation_id defines who caused this event

correlation_id: Option<Uuid>

a correlation_id correlates multiple events

event_type: String

Human readable event type

data: Value

Payload of this event

metadata: Value

Metadata defined for this event

event_uuid: Uuid

stream_uuid: String

stream_version: u64

created_at: DateTime<Utc>

Implementations

impl UnsavedEvent

pub fn try_from<E: Event>(event: &E) -> Result<Self, UnsavedEventError>

Try to create an UnsavedEvent from a struct that implement Event.

In case of a success an UnsavedEvent is returned with no context or metadata.

Errors

If serde isn’t able to serialize the Event an UnsavedEventError::SerializeError is returned

Trait Implementations

impl Clone for UnsavedEvent

fn clone(&self) -> UnsavedEvent

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UnsavedEvent

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<UnsavedEvent> for UnsavedEvent

fn eq(&self, other: &UnsavedEvent) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
