# [−] [src] Module typenum::marker_traits

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::{N42, Integer};

    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.
