Int and Integer traits should imply "Ord"

[haberman]

Right now the Int and Integer traits imply PartialOrd but not Ord.

Is there a reason for this? It seems like integers do have a total order, not just partial. I asked on IRC and people seemed to think Int should imply Ord.

If this is correct I can send a pull request?

Yup :)

@haberman I have two questions:

May I ask what is the Integer trait? Couldn't find any in the std doc:

• http://doc.rust-lang.org/std/?search=Integer

Did you mean std::num::Int (core::num::Int) when you wrote "the Int trait"? But it doesn't even inherit PartialOrd. Am I missing something?

@nodakai The Integer trait is in the num crate.

@japaric Ah, it was the big int code separated from the std lib! Thanks.

I also overlooked std::num::Int implemented Primitive, implying PartialOrd. Sorry for the noise!
