Description

template<typename ELM>
struct lib::diff::can_wrap_in_GenNode< ELM >

metafunction to detect types able to be wrapped into a GenNode.

Only a limited and fixed set of types may be placed within a GenNode, as defined through the typelist lib::diff::DataValues. This metafunction allows to enable or disable specialisations and definitions based on the fact if a type in question can live within a GenNode.
