Add a travis builder for wasm32-unknown-emscripten
This commits add an entry to travis matrix that will execute wasm32-unknown-emscripten tests suites.
- Emscripten for asmjs was updated to sdk-1.37.13-64bit
- The tests are run with node 8.0.0 (it can execute wasm)
- A wrapper script is used to run each test from the directory where it is (workaround for https://github.com/kripken/emscripten/issues/4542)
- Some tests are ignore, see #42629 and #42630

Pursuant to issue #25663, this commit adds the max and min functions to the Ord trait, enabling items that implement Ord to use UFCS (ex. 1.max(2)) instead of the longer std::cmp::max(1,2) format.

Deprecate range-specific `step_by`
Deprecation attributes and test updates only.
Was replaced by an any-iterator version in https://github.com/rust-lang/rust/pull/41439
Last follow-up (this release) to https://github.com/rust-lang/rust/pull/42110#issuecomment-303210138

Add an in-place rotate method for slices to libcore
A helpful primitive for moving chunks of data around inside a slice.
For example, if you have a range selected and are drag-and-dropping it somewhere else (Example from [Sean Parent's talk](https://youtu.be/qH6sSOr-yk8?t=560)).
(If this should be an RFC instead of a PR, please let me know.)
Edit: changed example
|
|
|
|
Changed all the tests except test_range_step to use Iterator::step_by.
|
|
This makes the size_hint from things like `take` more precise.
|
|
Override size_hint and propagate ExactSizeIterator for iter::StepBy
Generally useful, but also a prerequisite for moving a bunch of unit tests off `Range*::step_by`.
A small non-breaking subset of https://github.com/rust-lang/rust/pull/42110 (which I closed).
Includes two small documentation changes @ivandardi requested on that PR.

Fixes https://github.com/rust-lang/rust/issues/42135
Found while fixing run-pass/range_inclusive test failure.

A helpful primitive for moving chunks of data around inside a slice.
In particular, adding elements to the end of a Vec then moving them
somewhere else, as a way to do efficient multiple-insert. (There's
drain for efficient block-remove, but no easy way to block-insert.)
Talk with another example: <https://youtu.be/qH6sSOr-yk8?t=560>

Not being an enum improves ergonomics, especially since NonEmpty could be Empty. It can still be iterable without an extra "done" bit by making the range have !(start <= end), which is even possible without changing the Step trait.
Implements RFC 1980

Step::replace_one should put a one, not a zero (Issue #41492)
Turns out all six of the replace_* impls were backwards.

Implement .rfind() for slice iterators Iter and IterMut
Just like the forward case find, implement rfind explicitly for slice iterators Iter and IterMut.

This change moves:
1. `libcoretest` into `libcore/tests`
2. `libcollectionstest` into `libcollections/tests`
This is a follow-up to #39561.
