Expand description
This crate gives you an opinionated way of implement CQRS/event sourcing.
Under the hood, without postgres
feature enabled, this crate just expose some traits that can
be used in order to implement your version of the CQRS/event sourcing pattern. The main actors
are the Aggregate
(with its manager), AggregateState
, store::EventStore
and the
store::StoreEvent
.
The approach is to have a way, at runtime, to reload the state from an event store.
This means that everytime an aggregate state is needed the state should be loaded So, for example
while using postgres
event store, everytime a state load is required a database query is
performed over the event store table.
Modules§
- Provides custom types.
Macros§
Structs§
- The internal state for an Aggregate. It contains:
Traits§
- The Aggregate trait is responsible for validating commands, mapping commands to events, and applying events onto the state.
