Resolve Collections

Use component.ResolveAll when a feature is extension-based and should run every registered implementation.

type Task interface {
	Run(context.Context) error
}

func RunTasks(ctx context.Context, container component.Container) error {
	tasks, err := component.ResolveAll[Task](ctx, container)
	if err != nil {
		return err
	}

	for _, task := range tasks {
		if err := task.Run(ctx); err != nil {
			return err
		}
	}

	return nil
}

Collections are useful for plugin-like application behavior:

• command line runners
• startup tasks
• route contributors
• configuration customizers
• framework extensions

Keep collection items small and independent. A failing item should return an error that makes the failing component easy to identify.
