Convert a value
to an object of type T.
Defined in header <boost/json/value_to.hpp>
template< class T, class U> T value_to( U const& jv) = delete;
This overload is deleted and participates
in overload resolution only when U
is not value.
The overload exists to prevent unintented creation of temporary value instances, e.g.
auto flag = value_to<bool>(true);
Convenience header <boost/json.hpp>
