is_path_like

Determine if T can be treated like std::filesystem::path during conversions.

Synopsis

Defined in header <boost/json/conversion.hpp>

template<
    class T>
struct is_path_like
Description

Given t, a glvalue of type T, if

then the trait provides the member constant value that is equal to true. Otherwise, value is equal to false.

Users can specialize the trait for their own types if they don't want them to be treated like filesystem paths. For example:

namespace boost {
namespace json {

template <>
struct is_path_like<your::path> : std::false_type
{ };

} // namespace boost
} // namespace json
Types satisfying the trait

std::filesystem::path, boost::filesystem::path.
