Trait ViewStateComputation

pub trait ViewStateComputation<E, S> {
    // Required method
    fn compute_new_state(&self, current_state: Option<S>, events: &[&E]) -> S;
}

Formalizes the State Computation algorithm for the view to handle events based on the current state, and produce new state.

Required Methods

fn compute_new_state(&self, current_state: Option<S>, events: &[&E]) -> S

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