This version of Boost is under active development. You are currently in the master branch. The current version is 1.91.0.
Performs an element by element swap of the elements in 2 sequences.
template<typename Seq1, typename Seq2>
typename result_of::swap<Seq1, Seq2>::type
swap(Seq1& seq1, Seq2& seq2);

The sequences whose elements we wish to swap. |
swap(seq1, seq2);
Return type: void
Precondition: size(seq1) == size(seq2)
Semantics: Calls swap(a1, b1) for corresponding elements in seq1 and seq2.

vector<int, std::string> v1(1, "hello"), v2(2, "world"); swap(v1, v2); assert(v1 ==make_vector(2, "world")); assert(v2 ==make_vector(1, "hello"));
