This struct template implements a meta‐function to determine whether the (template parameter) t_TYPE is copy constructible. This struct derives from bsl::true_type if the t_TYPE is copy constructible, and from bsl::false_type otherwise. This meta‐function has the same syntax as the is_copy_constructible meta‐function defined in the C++11 standard [meta.unary.prop]; on C++03 platforms, however, this meta‐function defaults to true_type for all types that are not explicitly declared to have the bslmf::IsNonCopyable trait using the BSLMF_NESTED_TRAIT_DECLARATION macro. To mark a type as non‐copyable, bslmf::IsNonCopyable must be specialized (for that type) to inherit from bsl::true_type.
