Classes
struct	stan::is_constant< T, typename >
	Metaprogramming struct to detect whether a given type is constant in the mathematical sense (not the C++ const sense). More...
struct	stan::is_constant< T, require_std_vector_t< T > >
	Defines a static member named value and sets it to true if the type of the elements in the provided std::vector is constant, false otherwise. More...
struct	stan::is_constant< T, require_eigen_t< T > >
	Defines a public enum named value and sets it to true if the type of the elements in the provided Eigen Matrix is constant, false otherwise. More...

Namespaces
namespace	stan
	The lgamma implementation in stan-math is based on either the reentrant safe lgamma_r implementation from C or the boost::math::lgamma implementation.

Typedefs
template<typename... T>
using	stan::is_constant_all = math::conjunction< is_constant< T >... >
	Metaprogram defining an enum value which is true if all of the type parameters are constant (i.e., primitive types) and false otherwise.

Variables
template<typename... T>
constexpr bool	stan::is_constant_all_v = is_constant_all<std::decay_t<T>...>::value
template<typename T >
constexpr bool	stan::is_constant_v = is_constant<std::decay_t<T>>::value
