Specifica che un'istanza del tipo può essere assegnato dal muoversi (spostato). Questo significa che il tipo ha semantica movimento: cioè, in grado di trasferire il suo stato interno a un'altra istanza dello stesso tipo potenzialmente minimizzare l'overhead.

Original:

Specifies that an instance of the type can be move-assigned (moved). This means that type has move semantics: that is, can transfer its internal state to another instance of the same type potentially minimizing the overhead.

Type::operator=

Type& Type::operator=( Type&& other ); Type& Type::operator=(const Type&& other ); Type& Type::operator=(volatile Type&& other ); Type& Type::operator=(constvolatile Type&& other );		(Una delle varianti è sufficiente)

Spostare operatore di assegnazione: assigns the contents of other. The internal state of other is unspecified after the move. However, it must still be valid, that is, no invariants of the type are broken. The function must return *this.

The following expressions must have the specified effects:

a = rv;	a è equivalente a rv, dove a è un'istanza di Type e rv è un rvalue riferimento di Type .
