Trait EventRecord 

pub trait EventRecord<E> {
    // Required methods
    fn index(&self) -> u32;
    fn recorded_at(&self) -> DateTime<Utc>;
    fn idempotency_key(&self) -> Option<String>;
    fn event(&self) -> E;
}

Represents an event read from an EventStore.

Event stores implement this trait directly on their native row/record objects so that they don’t have to allocate and copy the data. An Aggregate will get these passed to its Aggregate::apply method.

Required Methods

fn index(&self) -> u32

Returns the zero-based sequential index of the event in its log.

fn recorded_at(&self) -> DateTime<Utc>

Returns the wall-clock time when this event was recorded in the EventStore. This is for informational purposes only since clocks on different service instances using this library could be skewed.

fn idempotency_key(&self) -> Option<String>

Returns the idempotency key that was used (if any) when appending this event to the log.

fn event(&self) -> E

Returns the event.
