Struct Repository 

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

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

A Repository instruments an EventStore to:

Implementations§

Source§

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

Source

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

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

Source§

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

Source

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

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.

Source

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

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.

Source

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

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