Trait EventComputation 

pub trait EventComputation<C, S, E, Error = ()> {
    // Required method
    fn compute_new_events(
        &self,
        current_events: &[E],
        command: &C,
    ) -> Result<Vec<E>, Error>;
}

Formalizes the Event Computation algorithm / event sourced system for the decider to handle commands based on the current events, and produce new events.

Required Methods

fn compute_new_events( &self, current_events: &[E], command: &C, ) -> Result<Vec<E>, Error>

Computes new events based on the current events and the command.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
