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, as well as associated constants that do the same.

For example, the `Integer` trait includes the function (among others) `fn to_i32() -> i32` and the associated constant `I32` so that one can do this:

    use typenum::{Integer, N42};

    assert_eq!(-42, N42::to_i32());
    assert_eq!(-42, N42::I32);

## Traits

Bit
The marker trait for compile time bits.
Integer
The marker trait for compile time signed integers.
NonZero
A marker trait to designate that a type is not zero. All number types in this crate implement `NonZero` except `B0`, `U0`, and `Z0`.
Ord
A Marker trait for the types `Greater`, `Equal`, and `Less`.
PowerOfTwo
The marker trait for type-level numbers which are a power of two.
TypeArray
The marker trait for type-level arrays of type-level numbers.
Unsigned
The marker trait for compile time unsigned integers.
Zero
A marker trait to designate that a type is zero. Only `B0`, `U0`, and `Z0` implement this trait.
