Trait eventually_core::aggregate::AggregateExt

pub trait AggregateExt: Aggregate {
    fn root(&self) -> AggregateRoot<Self>
    where
        Self: Sized + Clone,
        Self::State: Default,
    { ... }
    fn fold<I>(

        events: I
    ) -> Result<Self::State, Self::Error>

}

Extension trait with some handy methods to use with Aggregates.

Provided methods

fn root(&self) -> AggregateRoot<Self> where
    Self: Sized + Clone,
    Self::State: Default, 

Constructs a new, empty AggregateRoot using the current Aggregate.

fn fold<I>(state: Self::State, events: I) -> Result<Self::State, Self::Error> where
    I: Iterator<Item = Self::Event>, 

Applies a list of Events from an Iterator to the current Aggregate State.

Useful to recreate the State of an Aggregate when the Events are located in-memory.
