:mrdocs:

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`.
