Trait EffectSystem 

pub trait EffectSystem {
    type State;
    type Effect;

    // Required methods
    fn apply(&self, state: &mut Self::State, effect: &Self::Effect);
    fn react(
        &self,
        state: &mut Self::State,
        effect: &Self::Effect,
    ) -> Vec<Self::Effect>;
}

A game that resolves effects through a queue.

The move logic (Game::apply) builds the initial effects of a move and calls resolve_effects; the queue does the rest.

Required Associated Types

type State

The state effects mutate.

type Effect

One atomic effect (a game-defined enum).

Required Methods

fn apply(&self, state: &mut Self::State, effect: &Self::Effect)

Applies one effect’s direct consequence to state.

fn react( &self, state: &mut Self::State, effect: &Self::Effect, ) -> Vec<Self::Effect>

After effect is applied, performs state-based actions (deaths, removals) and returns the follow-up effects they trigger, in deterministic order. Returned effects are appended to the queue and resolved later, never inline.
