Struct DecisionMaker 

pub struct DecisionMaker<SS> { /* private fields */ }

The DecisionMaker struct is responsible for executing and persisting business decisions.

Implementations

impl<SS> DecisionMaker<SS>

pub fn new(state_store: SS) -> Self

Creates a new instance of DecisionMaker.

Parameters

• state_store: The state store backend used by the DecisionMaker to load the current state and persist the decision.

pub async fn make<D, S, ID, E>( &self, decision: D, ) -> Result<Vec<PersistedEvent<ID, E>>, Error<D::Error>>

where ID: EventId, E: Event + Clone + Sync + Send + 'static, SS: LoadState<ID, S, E> + PersistDecision<ID, S, E>, D: Decision<StateQuery = S, Event = E>, S: Send + Sync + Serialize + DeserializeOwned + IntoStatePart<ID, S>, <S as IntoStatePart<ID, S>>::Target: Send + Sync + Serialize + DeserializeOwned + IntoState<S> + MultiState<ID, E>, <D as Decision>::Error: 'static,

Makes the given business decision, persisting the resulting events in the event store.

Parameters

• decision: The business decision to be executed, implementing the Decision trait.

Returns

A Result indicating the success of the decision-making process. If successful, it contains a vector of PersistedEvent representing the changes made. In case of an error, it contains details about the encountered issue.

Trait Implementations

impl<SS: Clone> Clone for DecisionMaker<SS>

fn clone(&self) -> DecisionMaker<SS>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)
