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.

Dyn Compatibility

This trait is dyn compatible.

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