/*!

These are all of the **marker traits** used in typenum. Note that the definition here
for marker traits is slightly different than the conventional one --- we include traits
with functions that convert a type to the corresponding value.

For example, the `Integer` trait includes the function (among others) `fn to_i32() ->
i32` so that one can do this:

```
use typenum::{N42, Integer};

assert_eq!(-42, N42::to_i32());
```

implement `NonZero` except `B0`, `U0`, and `Z0`.

This trait should not be implemented for anything outside this crate.
