arg_t

template<typename CRTP , bool fixed_args, typename ... Args>

template<std::size_t Idx>

using molpro::linalg::itsolv::log::ContextBase< CRTP, fixed_args, Args >::arg_t = decltype(to_arg(std::declval<std::tuple_element_t<Idx, arg_types_tuple> >()))

The type if the Idx-th argument that uses of this log context imply. Only applies if the context actually uses a fixed argument set.

arg_types_tuple

template<typename CRTP , bool fixed_args, typename ... Args>

using molpro::linalg::itsolv::log::ContextBase< CRTP, fixed_args, Args >::arg_types_tuple = std::tuple<std::remove_cvref_t<Args>...>

get_arg()

template<typename CRTP , bool fixed_args, typename ... Args>

template<std::size_t Idx, typename ... Ts>

static arg_t< Idx > molpro::linalg::itsolv::log::ContextBase< CRTP, fixed_args, Args >::get_arg ( Ts &&...  args )

inlinestatic

Extracts the requested argument from the provided argument pack

to_arg()

template<typename CRTP , bool fixed_args, typename ... Args>

template<typename T >

static constexpr decltype(auto) molpro::linalg::itsolv::log::ContextBase< CRTP, fixed_args, Args >::to_arg ( T &&  arg )

inlinestaticconstexpr

Converts the given object to the type it should be handled as in downstream log handlers. For non-ranges that means ensuring the type is const a const reference whereas for ranges, we convert them to a view (as const ranges can't be iterated over in the general case).
