Here's the issue: https://github.com/rust-lang/rust/issues/15333
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.
This was parsed by the parser but completely ignored; not even stored in
the AST!
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.

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.
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
}
}

url.path - Now a Path instead of a String.
To fix old code:
url.path => url.path.path
url.query => url.path.query
url.fragment => url.path.fragment
Not much point having the Path struct if it's not going to be used.

url::path_from_str => url::Path::parse_str
The FromStr trait still works, but its confusing to have a path_from_str
free function that retuns a Result, while the regular from_str style
functions return an Option, hence the rename to indicate a Result.

- When the timezone is UTC, the "zone" field of the RFC 822 format is
"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
relation between ISO 8601 and RFC 3999.

This can break code that looked like:
struct S<T> {
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> {
// ^ remove `Copy` bound
...
}
Closes#14061.

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.
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...

One of the examples in the docs on adding documentation to rust code has an error that will cause the function to run endlessly rather than return the desired result, should someone actually implement this for some reason. While the error does not hinder the explanation of documenting code, it does look better if it is corrected.
