Module trigger 

Generic trigger handler trait and types for entity lifecycle events.

Deprecated. Nothing calls this registry, and ActionExecutor only logs. Hook triggers: now run in the write’s transaction through crate::write_hooks: the schema generator emits a <Model>WriteHooks that runs a trigger’s compilable actions and a <Model>Triggers trait for the rest. This module stays for one minor release so code that names it still builds, and is removed after it.

Phase 0 generic base for the trigger.rs generator (Category C).

Every generated {Model}TriggerHandler used to re-define the same boilerplate. This module provides the single generic version so that generated files collapse to type aliases:

use backbone_core::trigger::{TriggerEvent, TriggerContext, TriggerContextMut,
                              TriggerRegistry, ActionExecutor, TriggerHandler};
use crate::domain::entity::Order;

pub type OrderTriggerEvent      = TriggerEvent;
pub type OrderTriggerContext    = TriggerContext<Order>;
pub type OrderTriggerContextMut = TriggerContextMut<Order>;
pub type OrderActionExecutor    = ActionExecutor;
pub type OrderTriggerRegistry   = TriggerRegistry<Order>;
pub type OrderTriggerHandlerObj = dyn TriggerHandler<TriggerContext<Order>, TriggerEvent>;
