3768,Incomplete documentation for type_traits::extent and type_traits::rank,Edward Diener <eld@…>,John Maddock,"The documentation for type_traits::extent is:

""Inherits: Class template extent inherits from integral_constant<std::size_t, EXTENT(T,N)>, where EXTENT(T,N) is the number of elements in the N'th array dimention of type T.

If T is not an array type, or if N > rank<T>::value, or if the N'th array bound is incomplete, then EXTENT(T,N) is zero.""

This does not explain what this type_traits is about.

The documentation for type_traits::rank is:

"" Inherits: Class template rank inherits from integral_constant<std::size_t, RANK(T)>, where RANK(T) is the number of array dimensions in type T.

If T is not an array type, then RANK(T) is zero. ""

This does not explain what this type_traits is about.

Decent documentation for both of these would be welcome.",Bugs,closed,Boost 1.42.0,type_traits,Boost 1.41.0,Cosmetic,fixed,extent rank,
