std::queue::swap

void swap( queue& other ) noexcept(/* see below */);

(since C++11)

Exchanges the contents of the container adaptor with those of other. Effectively calls using std::swap; swap(c, other.c);

other

container adaptor to exchange the contents with

(none).

In the `noexcept` expressions below, the identifier `swap` is looked up in the same manner as the C++17 `std::is_nothrow_swappable` trait. `noexcept` specification: `noexcept(noexcept(swap(c, other.c)))`	(until C++17)
`noexcept` specification: `noexcept(std::is_nothrow_swappable<Container>::value)`	(since C++17)

Same as underlying container (typically constant).
