// SWIG Macros to use std::pair<T, U> OUTPUT in Python,
//
// Normally we'd simply use:
// ```swig
// %include "std_pair.i"
// %template(IntBoolPair) std::pair<int, bool>;
// ```
// see http://swig.org/Doc4.1/Library.html#Library_std_vector), but
// here we can't, because exceptions are forbidden and std_pair.i will rely on
// on python/pystdcommon.swg which use few throw in type traits...

%include "ortools/base/base.i"

%typemap(out) std::pair<int, bool> {
  $result = Py_BuildValue("(ib)", $1.first, $1.second);
