Classes
struct	kamping::types::mpi_type_traits< T, Enable >
	The type trait that maps a C++ type T to an MPI_Datatype for the kamping-types module. More...
struct	kamping::types::mpi_type_traits< T, std::enable_if_t< has_auto_dispatched_type_v< T > > >
	Partial specialization of kamping::types::mpi_type_traits for types matched by kamping::types::type_dispatcher(). More...
struct	kamping::types::has_static_type< typename, Enable >
	Check if the type has a static type definition, i.e. kamping::types::mpi_type_traits is defined. More...
struct	kamping::types::has_static_type< T, std::void_t< decltype(mpi_type_traits< T >::data_type())> >
	Check if the type has a static type definition, i.e. kamping::types::mpi_type_traits is defined. More...
struct	kamping::types::type_dispatcher_lookup
	Default lookup policy for contiguous_type and struct_type. More...

Functions
template<typename T >
auto	kamping::types::type_dispatcher ()
	Maps a C++ type T to a type trait for constructing an MPI_Datatype.

Variables
template<typename T >
static constexpr bool	kamping::types::has_auto_dispatched_type_v
	Whether the type is handled by the auto-dispatcher kamping::types::type_dispatcher().
template<typename T >
static constexpr bool	kamping::types::has_static_type_v = has_static_type<T>::value
	true if kamping::types::mpi_type_traits provides a data_type() function.
