Deduction guides

 

void swap( flat_multimap& other )noexcept;		(since C++23)

Exchanges the contents of the container adaptor with those of other. Effectively calls

ranges::swap(compare, other.compare);ranges::swap(c.keys, other.c.keys);ranges::swap(c.values, other.c.values);

Parameters

other

-

container adaptor to exchange the contents with

Return value

(none)

Exceptions

(none)

Complexity

Same as underlying container (typically constant).
