Enum cqrs_core::Since

pub enum Since {
    BeginningOfStream,
    Event(EventNumber),
}

The starting point when reading a stream of values from an [EventSource].

Variants

BeginningOfStream

Begins reading events from the very beginning of the stream.

Event(EventNumber)

Begins reading events after the given EventNumber.

E.g. if the event number were 4, then reading should begin at event number 5.
