Struct Repository

pub struct Repository<T, Store>where
    T: Aggregate + Clone + 'static,
    Store: EventStore<SourceId = T::Id, Event = T::Event>,
{ /* private fields */ }

Expand description

Implementation of the Repository pattern for storing, retrieving and deleting Aggregates.

A Repository instruments an EventStore to:

Insert Events in the EventStore for an Aggregate, using the AggregateRoot,
Get all the Events in the EventStore and rebuild the State of an Aggregate, into a new AggregateRoot instance,
Remove all the Events for an Aggregate in the EventStore.

Implementations§

impl<T, Store> Repository<T, Store>
where T: Aggregate + Clone, Store: EventStore<SourceId = T::Id, Event = T::Event>,

pub fn new(builder: AggregateRootBuilder<T>, store: Store) -> Self

Creates a new Repository instance, using the Aggregate and EventStore provided.

impl<T, Store> Repository<T, Store>
where T: Aggregate + Clone, T::Id: Debug + Clone, T::Event: Clone, T::Error: Error + 'static, Store: EventStore<SourceId = T::Id, Event = T::Event>, Store::Error: Error + 'static,

pub async fn get(&self, id: T::Id) -> Result<AggregateRoot<T>, T, Store>

Returns the Aggregate from the Repository with the specified id, if any.

In case the Aggregate with the specified id exists, returns a new AggregateRoot instance with its latest State.

Otherwise, None is returned.

pub async fn add( &mut self, root: AggregateRoot<T>, ) -> Result<AggregateRoot<T>, T, Store>

Adds a new State of the Aggregate into the Repository, through an AggregateRoot instance.

Returns Error::NoEvents if there are no Events to commit in the AggregateRoot.

pub async fn remove(&mut self, id: T::Id) -> Result<(), T, Store>

Removes the specified Aggregate from the Repository, using the provided AggregateId.
