Is it possible to append to an std::vector another std::vector by moving the second into the first?
If so, how?
I'm only aware of this syntax to perform the append operation:
vec_a.insert( vec_a.end(), vec_b.begin( ), vec_b.end( ) );

What do you want to achieve? Omit a copy of the appended elements? That's not possible as each vector uses its own internal, continuous storage on the heap. – ypnos Feb 24 '16 at 16:00

@ypnos sometimes objects are movable but not copiable – user3528438 Feb 24 '16 at 16:01
