Trait StateComputation 

pub trait StateComputation<C, S, E, Error = ()> {
    // Required method
    fn compute_new_state(
        &self,
        current_state: Option<S>,
        command: &C,
    ) -> Result<S, Error>;
}

Formalizes the State Computation algorithm / state-stored system for the decider to handle commands based on the current state, and produce new state.

Required Methods

fn compute_new_state( &self, current_state: Option<S>, command: &C, ) -> Result<S, Error>

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

Dyn Compatibility

This trait is dyn compatible.

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