Notas

Este rasgo tipo es utilizado por std::scoped_allocator_adaptor y puede ser utilizado por los asignadores personalizados para determinar si el objeto en construcción en sí es capaz de utilizar un asignador (por ejemplo, es un contenedor), en cuyo caso debe ser un asignador pasó a su constructor .

Original:

This type trait is used by std::scoped_allocator_adaptor and may be used by custom allocators to determine whether the object being constructed is itself capable of using an allocator (e.g. is a container), in which case an allocator should be passed to its constructor.
