Forward more ExactSizeIterator methods and `is_empty` edits - Forward ExactSizeIterator methods in more places, like `&mut I` and `Box<I>` iterator impls. - Improve `VecDeque::is_empty` itself (see commit 4) - All the collections iterators now have `len` or `is_empty` forwarded if doing so is a benefit. In the remaining cases, they already use a simple size hint (using something like a stored `usize` value), which is sufficient for the default implementation of len and is_empty.

2016-12-04alloc: Forward ExactSizeIterator methods in Iterator for Box<I>Ulrik Sverdrup-1/+9
2016-12-02core: Remove Self: Sized from Iterator::nthUlrik Sverdrup-0/+3
It is an unnecessary restriction; nth neither needs self to be sized nor needs to be exempted from the trait object. It increases the utility of the nth method, because type specific implementations are available through `&mut I` or through an iterator trait object. It is a backwards compatible change due to the special cases of the `where Self: Sized` bound; it was already optional to include this bound in `Iterator` implementations.

2016-11-08Auto merge of #37192 - cristicbz:rust-rc-into-raw, r=brsonbors-0/+190
Add `{into,from}_raw` to Rc and Arc These methods convert to and from a `*const T` for `Rc` and `Arc` similar to the way they work on `Box`. The only slight complication is that `from_raw` needs to offset the pointer back to find the beginning of the `RcBox`/`ArcInner`. I felt this is a fairly small addition, filling in a gap (when compared to `Box`) so it wouldn't need an RFC. The motivation is primarily for FFI. (I'll create an issue and update a PR with the issue number if reviewers agree with the change in principle **Edit: done #37197**) ~~Edit: This was initially `{into,from}_raw` but concerns were raised about the possible footgun if mixed with the methods of the same name of `Box`.~~ Edit: This was went from `{into,from}_raw` to `{into,from}_inner_raw` then back to `{into,from}_raw` during review.

2016-11-06Add a comment to `Arc::MAX_REFCOUNT`Daan Sprenkels-0/+4
The constant name `MAX_REFCOUNT` suggests that the value is a _hard_ limit on the amount of references to an `Arc`. This is a more soft limit however. This commit adds a comment to the constant to annotate this. See also: PR #37605

2016-09-30Auto merge of #36339 - brson:emscripten-new, r=alexcrichtonbors-0/+1
Working asmjs and wasm targets This patch set results in a working standard library for the asmjs-unknown-emscripten and wasm32-unknown-emscripten targets. It is based on the work of @badboy and @rschulman. It does a few things: - Updates LLVM with the emscripten [fastcomp](https://github.com/rust-lang/llvm/pull/50) patches, which include the pnacl IR legalizer and the asm.js backend. This patch is thought not to have any significant effect on existing targets. - Teaches rustbuild to correctly link C code with emscripten - Updates gcc-rs to work correctly with emscripten - Teaches rustbuild to run crate tests for emscripten with node - Modifies Thread::new to return an error on emscripten, to facilitate debugging a common failure mode - Modifies libtest to run in single-threaded mode for emscripten - Ignores a host of tests that don't work yet, mostly dealing with threads and I/O - Updates libc with wasm32 definitions (presently the same as asmjs) - Adds a wasm32-unknown-emscripten target that feeds the output of LLVM's asmjs backend through emcc to generate wasm Notes and caveats: - This is only known to work with `--enable-rustbuild`. - The wasm32 target can't be tested correctly yet because of issues in compiletest and limitations in node https://github.com/kripken/emscripten/issues/4542, but hello.rs does seem to work when run on node via the binaryen interpreter - This requires an up to date installation of the emscripten sdk from its incoming branch - Unwinding is very broken - When enabling the emscripten targets jemalloc is disabled for all targets, which results in test failures for the host Next steps are to fix the jemalloc issue, start building the two emscripten targets on the auto builders, then start producing nightlies. https://github.com/rust-lang/rust/issues/36317 tracks work on this.

Implement 1581 (FusedIterator) * [ ] Implement on patterns. See https://github.com/rust-lang/rust/issues/27721#issuecomment-239638642. * [ ] Handle OS Iterators. A bunch of iterators (`Args`, `Env`, etc.) in libstd wrap platform specific iterators. The current ones all appear to be well-behaved but can we assume that future ones will be? * [ ] Does someone want to audit this? On first glance, all of the iterators on which I implemented `FusedIterator` appear to be well-behaved but there are a *lot* of them so a second pair of eyes would be nice. * I haven't touched rustc internal iterators (or the internal rand) because rustc doesn't actually call `fuse()`. * `FusedIterator` can't be implemented on `std::io::{Bytes, Chars}`. Closes: #35602 (Tracking Issue) Implements: rust-lang/rfcs#1581

Revise wording in Rc documentation. The term "thread-local" has a widely accepted meaning which is not the meaning it's used for here.
