Classes
struct	std::common_type< jsonv::result< TValue1, TError1 >, jsonv::result< TValue2, TError2 > >
class	jsonv::ok< TValue >
	A wrapper type for creating a result with result_state::ok. More...
class	jsonv::ok< void >
	The void specialization of ok is meant for the creation of result instances with value_type of void. More...
class	jsonv::error< TError >
	A wrapper type for creating a result with result_state::error. More...
class	jsonv::error< void >
	The void specialization of error is meant for the creation of result instances with error_type of void. More...
class	jsonv::bad_result_access
	Thrown when an attempt to access the contents of a result was illegal. More...
class	jsonv::result_value_operations< TSelf, TValue >
	The set of result operations which depend on the type of TValue. More...

struct	jsonv::in_place_error_t
class	jsonv::result< TValue, TError >
