zackmdavis:missing_sum_and_product_for_128_bit_integers, r=nagisa add u128/i128 to sum/product implementors Resolves #43235.
2017-07-16Auto merge of #43252 - vbrandl:doc/default-values, r=GuillaumeGomezbors-18/+19
Document default values for primitive types All primitive types implement the `Default` trait but the documentation just says `Returns the "default value" for a type.` and doesn't give a hint about the actual default value. I think it would be good to document the default values in a proper way. I changed the `default_impl` macro to accept a doc string as a third parameter and use this string to overwrite the documentation of `default()` for each primitive type. The generated documentation now looks like this: ![Documentation of default() on the bool primitive](https://i.imgur.com/nK6TApo.png)

2017-07-14Rollup merge of #43159 - cuviper:ptr-swap-simd, r=arielb1Corey Farwell-1/+4
Disable big-endian simd in swap_nonoverlapping_bytes This is a workaround for #42778, which was git-bisected to #40454's optimizations to `mem::swap`, later moved to `ptr` in #42819. Natively compiled rustc couldn't even compile stage1 libcore on powerpc64 and s390x, but they work fine without this `repr(simd)`. Since powerpc64le works OK, it seems probably related to being big-endian. The underlying problem is not yet known, but this at least makes those architectures functional again in the meantime. cc @arielb1

2017-07-13Forward more Iterator methods for iter::RevSimon Sapin-0/+8
`position` could not be implemented because calling `rposition` on the inner iterator would require more trait bounds.

Correct some stability attributes These show up in rustdoc so need to be correct.
2017-07-12Rollup merge of #43011 - qnighy:unsized-tuple-impls, r=aturonMark Simulacrum-7/+23
Implement Eq/Hash/Debug etc. for unsized tuples. As I mentioned in [the comment in #18469](https://github.com/rust-lang/rust/issues/18469#issuecomment-306767422), the implementations of `PartialEq`, `Eq`, `PartialOrd`, `Ord`, `Debug`, `Hash` can be generalized to unsized tuples. This is consistent with the `derive` behavior for unsized structs. ```rust #[derive(Clone, Copy, PartialEq, Eq, PartialOrd, Ord, Debug, Default, Hash)] struct MyTuple<X, Y, Z: ?Sized>(X, Y, Z); fn f(x: &MyTuple<i32, i32, [i32]>) { x == x; x < x; println!("{:?}", x); } ``` Questions: - Need an RFC? - Need a feature gate? I don't think it does because the unsized tuple coercion #42527 is feature-gated. - I changed `builder.field($name);` into `builder.field(&$name);` in the `Debug` implementation to pass compilation. This won't affect the behavior because `Debug for &'a T` is a mere redirection to `Debug for T`. However, I don't know if it affects code size / performance.
2017-07-12Rollup merge of #42670 - dns2utf8:panic_return_code, r=steveklabnikMark Simulacrum-1/+1
Add hint about the return code of panic! I hope the link works on all cases, since the `unreachable` doc is copied to `std::` as well.

2017-07-04Rollup merge of #42836 - rthomas:29355-debug, r=GuillaumeGomezMark Simulacrum-10/+129
Update docs for Debug* structs. #29355 This adds docs for the Debug* structs as well as examples from the Formatter::debug_* methods, so that a user knows how to construct them. I added these examples as the builders module is not public and hence the debug_*_new() functions are not available to a user. r? @steveklabnik
2017-07-04Auto merge of #43012 - scottmcm:delete-range-step-by, r=alexcrichtonbors-246/+16
Delete deprecated & unstable range-specific `step_by` Using the new one is annoying while this one exists, since the inherent method hides the one on iterator. Tracking issue: #27741 Replacement: #41439 Deprecation: #42310 for 1.19 Fixes #41477

I added these examples as the builders module is not public and hence the debug_*_new() functions are not available to a user. r? @steveklabnik Review comments. Mainly adding in the links for all of the structs and functions. Remove rust tag on code blocks.

Revert "Stabilize RangeArgument" This reverts commit 143206d54d7558c2326212df99efc98110904fdb. From the discussion in #30877 it seems like this is premature.

2017-06-30Track `iterator_for_each` in #42986Josh Stone-1/+1
2017-06-30Auto merge of #42782 - cuviper:iterator_for_each, r=alexcrichtonbors-0/+94
Add `Iterator::for_each` This works like a `for` loop in functional style, applying a closure to every item in the `Iterator`. It doesn't allow `break`/`continue` like a `for` loop, nor any other control flow outside the closure, but it may be a more legible style for tying up the end of a long iterator chain. This was tried before in #14911, but nobody made the case for using it with longer iterators. There was also `Iterator::advance` at that time which was more capable than `for_each`, but that no longer exists. The `itertools` crate has `Itertools::foreach` with the same behavior, but thankfully the names won't collide. The `rayon` crate also has a `ParallelIterator::for_each` where simple `for` loops aren't possible. > I really wish we had `for_each` on seq iterators. Having to use a > dummy operation is annoying. - [@nikomatsakis][1] [1]: https://github.com/nikomatsakis/rayon/pull/367#issuecomment-308455185
