This breaks code that looks like:

    static X: &'static [u8] = &'static [1, 2, 3];

Change this code to the shorter:

    static X: &'static [u8] = &[1, 2, 3];

Closes #15312.

This implementation does have the minor issue of not handling things correctly when a codepoint is split across multiple writes or reads, but its better than not having unicode support at all.

Adds a Windows specific struct `WindowsTTY` in `libnative` and make `tty_open` create that struct on Windows. Adds needed functions and constants to `c_win32.rs`.

Libuv still needs to be updated before #15028 can be closed.

Adds a WindowsTTY for libnative that converts between UTF-8 and UTF-16.

It was required to get iOS compilable but since
that time a couple of changes were introduced
which cause the same bug to re-appear and broke 
build anyway. Fixing all of them doesn’t look a 
viable alternative to me as it will pollute the 
code too much.

So it should be fixed from LLVM side and I hope 
LLVM will upstream corresponding changes in a 
month.

Meanwhile, who wants to play with Rust on iOS is 
better to use a fork which uses patched LLVM:
https://github.com/vhbit/rust/tree/ios . It may 
lag behind master a bit, but it is Travis-checked 
to compile successfully.

Unit-like struct patterns are irrefutable, no need for a branch.

And some cleanup while I'm at it.

A margin for the top level list was leaking into nested ones.

Tested it. It works. FYI, in case anyone doesn't know: keyboard shortcut `'` restricts text search to only links on Firefox allowing this to be checked easily.

In C, `ctime(t)` is equivalent to `asctime(localtime(t))`, so the result should depend on the local timezone. Current `ctime` is compatible with `asctime` in C, not `ctime`.

This commit renames `ctime` to `asctime` and adds `ctime` which converts the time to the local timezone before formatting it.

This commit also fixes the documentation of them. Current documentation of `ctime` says it returns "a string of the current time." However, it actually returns a string of the time represented as `self`, not the time when it is called.

parameters.

This can break code that mistakenly used type parameters in place of
`Self`. For example, this will break:

    trait Foo {
        fn bar<X>(u: X) -> Self {
            u
        }
    }

Change this code to not contain a type error. For example:

    trait Foo {
        fn bar<X>(_: X) -> Self {
            self
        }
    }

  "GMT" (or "UT"), not "UTC."

- Although the name of `rfc3999` refers to RFC 3999, the documentation
  of it refers only to ISO 8601. This commit adds a description of the

This can break code that looked like:

        val: T,
    }
    trait Gettable<T> {

    impl<T: Copy> Gettable<T> for S<T> {

    }
    let t: Box<S<String>> = box S {
        val: "one".to_string(),
    };
    let a = t as Box<Gettable<String>>;
    //                        ^ note no `Copy` bound

Change this code to:

    impl<T> Gettable<T> for S<T> {

Fixes #10536.

Fixes #15334.

Rationale: for what appear to be historical reasons only, the PatIdent contains
a Path rather than an Ident.  This means that there are many places in the code
where an ident is artificially promoted to a path, and---much more problematically---
a bunch of elements from a path are simply thrown away, which seems like an invitation
to some really nasty bugs.

This commit replaces the Path in a PatIdent with a SpannedIdent, which just contains an ident
and a span.

Just a few words about functions and defining them.

This commit changes `os` in three ways:

* It adds a `join_paths` function that is the converse to `split_paths`,
  easing manipulation of the `PATH` environment variable according to
  platform conventions.

* **Breaking change**: It changes `split_paths` to no longer drop empty paths, since they are
  meaningful to some shells (where they are synonymous with the current
  working directory).

* It changes `setenv` to take a `BytesContainer` rather than a `&str`
  value, since environment variables may have non-utf8 values on some
  platforms. Since `&str` is a `BytesContainer`, this is *not* a
  breaking change.

Along the way, it also refactors the `split_paths` function so that
`cfg` switches are applied internally (and the function header is given
only once). This fixes a bug: the doc comment had an example for only
one platform.

This was causing lots of ICEs in cargo. I sadly wasn't ever able to reduce the
test case down, but I presume that's because it has to do with node id
collisions which are pretty difficult to turn up...
