[−][src]Struct eventually::Projector

pub struct Projector<P, S> where
    P: Projection,  { /* fields omitted */ }

A Projector manages the state of a single Projection by opening a long-running stream of all events coming from the EventStore.

New instances of a Projector are obtainable through a ProjectorBuilder instance.

The Projector will start updating the Projection state when run is called.

At each update, the Projector will broadcast the latest version of the Projection on a Stream obtainable through watch.
