Josh Stone 3ead4a16b5 Implement RefNum more generically 2017-05-06 21:35:38 -07:00
Josh Stone 21b520ea15 Add new traits for reference and assignment operators
There are two new "utility" traits covering the basic operators:
`Add`, `Sub`, `Mul`, `Div`, and `Rem`.

- `NumOps<Rhs, Output>`: operators with an arbitrary operand and output.
- `NumAssignOps<Rhs>`: assignment operators with an arbitrary operand.

Then the new collection of numeric traits are:

- `Num`: effectively unchanged, just taking operands by value.
- `NumRef`: `Num` adding reference operands on the right side.
- `RefNum`: `&T` operators, with either `T` or `&T` on the right side.
  - This does not specify `T: Num`, as rust-lang/rust#20671 means that
    could only add a constraint, without implying its presence for use.
- `NumAssign`: `Num` adding assignment operators by value.
- `NumAssignRef`: `NumAssign` adding reference assignment operators.
  - Nothing actually implements this yet!

Acknowledgement: this is roughly based on [@andersk's suggestion][1].

impl remaining num-traits for std::num::Wrapping<T>

This is a (late) follow-up for [https://github.com/rust-num/num/pull/279](https://github.com/rust-num/num/pull/279) since I realized that implementing `Num` for `Wrapping<T>` was merely half of the work.

This PR makes `Wrapping<T>` implement the remaining appropriate traits, granting it the ability to really be used a complete substitute for its primitive integer counterparts.
Some benefits are :
- Less refactoring for users using `num`'s traits replacing some primitives by their `Wrapping` counterpart (same for the opposite);
- Since `Wrapping<T>` is from `std`, nobody except us can `impl` our traits for it, so people don't have to create their own.

Homu aff06286ad Auto merge of #275 - bluss:repr-c, r=cuviper
Complex: Use repr(C) and add documentation for what it means

Here's an ambitious proposal that puts currently practiced ffi usage of `Complex<f32/f64>` on sound footing.

Fixes  #79

Current users appear to be:

- https://crates.io/crates/blas
  + Their use is not about Complex<f64> in an extern function's signature, but it is explicitly using that it is memory layout compatible.

Implement an iterator over the binomial coefficients

I'm not very happy with the excessive cloning, but to fix it the bounds on the type parameters would have to be excessive. We probably need something like [this](https://github.com/vks/discrete-log/blob/master/src/main.rs#L90) in `num-traits`.
