2016-11-04Auto merge of #37356 - cristicbz:wrapsum, r=alexcrichtonbors-52/+0
Add impls for `&Wrapping`. Also `Sum`, `Product` impls for both `Wrapping` and `&Wrapping`. There are two changes here (split into two commits): - Ops for references to `&Wrapping` (`Add`, `Sub`, `Mul` etc.) similar to the way they are implemented for primitives. - Impls for `iter::{Sum,Product}` for `Wrapping`. As far as I know `impl` stability attributes don't really matter so I didn't bother breaking up the macro for two different kinds of stability. Happy to change if it does matter.

2016-08-31Rollup merge of #35926 - matthew-piziak:bit-or-xor-examples, r=GuillaumeGomezJonathan Turner-18/+81
add evocative examples for `BitOr` and `BitXor` These are exactly equivalent to PR #35809, with one caveat: I do not believe there is a non-bitwise binary XOR operator in Rust, so here it's expressed as `(a || b) && !(a && b)`. Alternative decompositions are `(a && !b) || (!a && b)` and `(a || b) && (!a || !b)`. Let me know if you think one of those would be clearer. r? @GuillaumeGomez

2016-08-30Rollup merge of #35993 - matthew-piziak:bitwise-and-redux, r=GuillaumeGomezGuillaume Gomez-21/+41
improve `BitAnd` trait documentation This pull request is based on the discussion in PR #35927. Add a module-level note that `&&` and `||` are short-circuiting operators and not overloadable. Add a simple `Scalar` example that lifts the `&` operator to a trivial struct tuple. Make `BooleanVector` a struct tuple. Derive `PartialEq` for `BooleanVector` instead of implementing it. Adds a `fn main` wrapper so that the example can integrate with Rust Playground.

2016-08-30Rollup merge of #35810 - matthew-piziak:fn-trait-example, r=steveklabnikGuillaume Gomez-0/+165
improve documentation for `Fn*` traits This PR is not yet a serious attempt at contribution. Rather, I'm opening this for discussion. I can think of a few things we may want to accomplish with the documentation of the `Fn`, `FnMut`, and `FnOnce` traits: - the relationship between these traits and the closures that implement them - examples of non-closure implementations - the relationship between these traits and Rust's ownership semantics

2016-08-23improve documentation for `Fn*` traitsMatthew Piziak-0/+165
I can think of a few things we may want to accomplish with the documentation of the `Fn`, `FnMut`, and `FnOnce` traits: - the relationship between these traits and the closures that implement them - examples of non-closure implementations - the relationship between these traits and Rust's ownership semantics add module-level documentation for `Fn*` traits Describe how `Fn*` traits, closure types, and ownership semantics are linked, and provide examples of higher-level functions that take `Fn*`s. more examples for `Fn*` traits create correct (though not yet elegant) examples for `FnMut` and `FnOnce` add trait links to module-level documentation third time's a charm! argument -> capture for trait documentation This wording will need to be supported with better examples for capturing eventually. correct `FnOnce` example I also fixed some of the trait wording here to make the concept of capturing clearer; though that still needs more work. replace `x + x` with `x * 2` for `fn double`

2016-08-21Auto merge of #35777 - nrc:carrier3, r=@nikomatsakisbors-0/+72
Carrier trait (third attempt) This adds a `Carrier` trait to operate with `?`. The only public implementation is for `Result`, so effectively the trait does not exist, however, it ensures future compatibility for the `?` operator. This is not intended to be used, nor is it intended to be a long-term solution. Although this exact PR has not been through Crater, I do not expect it to be a breaking change based on putting numerous similar PRs though Crater in the past. cc: * [? tracking issue](https://github.com/rust-lang/rust/issues/31436) * [previous PR](https://github.com/rust-lang/rust/pull/35056) * [RFC issue](https://github.com/rust-lang/rfcs/issues/1718) for discussion of long-term Carrier trait solutions. r? @nikomatsakis

2016-08-20Rollup merge of #35709 - matthew-piziak:add-trait-example, r=GuillaumeGomezJonathan Turner-11/+23
replace `Add` example with something more evocative of addition Currently most of the operator traits use trivial implementation examples that only perform side effects. Honestly, that might not be too bad for the sake of documentation; but anyway, here's a proposal to move a slightly modified version of the module-level point-addition example into the `Add` documentation, since it's more evocative of addition semantics. Part of #29365
