Boost
C++ Libraries
...one of the most highly
regarded and expertly designed C++ library projects in the
world.

Alexandrescu, C++

This is an older version of Boost and was released in 2017. The current version is 1.92.0.
#include <boost/qvm/scalar_traits.hpp>
namespace boost
{
namespace qvm
{
template <class Scalar>
struct scalar_traits
{
BOOST_QVM_INLINE_CRITICAL
static Scalar value( int v )
{
return Scalar(v);
}
};
}
}
This template can be specialized for user-defined scalar types to define the appropriate conversion from int; this is primarily used whenever Boost QVM needs to deduce a zero or one value.
