Detailed Description

template<typename ctor>
struct boost::mpl11::datatype< ctor >

Returns the datatype of the given data constructor.

By default, this metafunction returns ctor::mpl_datatype if that expression is valid, and Foreign otherwise. It can also be specialized to customize the datatype of data constructors without requiring the constructor to have a nested mpl_datatype type.

Note

This metafunction must be invoked with an unboxed type. The reason for this special behavior is to allow specialization by users.
