atomic_ref::required_alignment
static constexpr std:: size_t required_alignment = /*implementation-defined*/ ;
(desde C++20)

El valor de required_alignment es la alineación requerida para que un objeto pueda ser referenciado por una referencia atómica, que es al menos alignof ( T ) .

Notas

El hardware podría requerir que un objeto referenciado por un atomic_ref<T> tenga una alineación más estricta que otros objetos T , y si las operaciones en un atomic_ref son libres de bloqueo puede depender de la alineación del objeto referenciado.
