This way all the other macros defined in this module, such as nonzero_leading_trailing_zeros, are available to call within the expansion of nonzero_integers. (Macros defined by macro_rules cannot be called from the same module above the location of the macro_rules.) In this commit the ability to call things like nonzero_leading_trailing_zeros is not immediately used, but later commits in this stack will be consolidating the entire API of NonZeroT to be generated through nonzero_integers, and will need to make use of some of the other macros to do that.
