Trait ActionHook 

pub trait ActionHook: Send {
    // Required methods
    fn before_action(&mut self, event: &BeforeActionEvent);
    fn after_action(&mut self, event: &AfterActionEvent);

    // Provided method
    fn name(&self) -> &str { ... }
}

Hook interface for action execution events

Implement this trait to receive notifications about action execution. Hooks are called in registration order.

Thread Safety

Hooks must be Send to support multi-threaded execution contexts. If your hook needs to share state, use Arc<Mutex<T>> or channels.

Required Methods

fn before_action(&mut self, event: &BeforeActionEvent)

Called before action execution

This hook is called before the action logic runs. Use this to:

• Log action invocations
• Prepare state for recording
• Update UI state (mark button as active)

Note: This hook cannot cancel action execution.

fn after_action(&mut self, event: &AfterActionEvent)

Called after action execution

This hook is called after the action completes (success or failure). Use this to:

• Record action events
• Update analytics
• Send network sync messages
• Update undo/redo buffers

The result field indicates whether execution succeeded.

Provided Methods

fn name(&self) -> &str

Optional: Hook name for debugging
