Detailed Description

template<typename T, typename Lookup = type_dispatcher_lookup>
struct kamping::types::struct_type< T, Lookup >

Constructs an MPI_Datatype for a struct-like type.

Template Parameters

T	The type to construct the MPI_Datatype for.
Lookup	The lookup policy used to resolve the MPI_Datatype for each field of T. Defaults to type_dispatcher_lookup, which uses kamping::types::mpi_type_traits.

This requires that T is a std::pair, std::tuple or a type that is reflectable with pfr. If you do not agree with PFR's decision if a type is implicitly reflectable, you can override it by providing a specialization of pfr::is_reflectable with the tag kamping_tag.
