Typedef Documentation
◆ RebindList
using Dune::Simd::RebindList = typedef typename Impl::RemoveEnd<EndMark, TypeList<Types...> >::type |
A list of types with the final element removed.
This is TypeList<NoEndTypes..>
, where NoEndTypes...
is Types...
with the final element removed. The final element in Types...
is required to be EndMark
.
This is useful to construct type lists in generated source files, since you don't need to avoid generating a trailing ,
in the list – just terminate it with EndMark
.
