This breaks code that referred to variant names in the same namespace as
their enum. Reexport the variants in the old location or alter code to
refer to the new locations:
```
pub enum Foo {
A,
B
}
fn main() {
let a = A;
}
```
=>
```
pub use self::Foo::{A, B};
pub enum Foo {
A,
B
}
fn main() {
let a = A;
}
```
or
```
pub enum Foo {
A,
B
}
fn main() {
let a = Foo::A;
}
```

except where trait objects are involved.
Part of issue #15349, though I'm leaving it open for trait objects.
Cross borrowing for trait objects remains because it is needed until we
have DST.
This will break code like:
fn foo(x: &int) { ... }
let a = box 3i;
foo(a);
Change this code to:
fn foo(x: &int) { ... }
let a = box 3i;
foo(&*a);

This breaks a fair amount of code. The typical patterns are:
* `for _ in range(0, 10)`: change to `for _ in range(0u, 10)`;
* `println!("{}", 3)`: change to `println!("{}", 3i)`;
* `[1, 2, 3].len()`: change to `[1i, 2, 3].len()`.
RFC #30. Closes #6023.

Previously, the type system's restrictions on borrowing were summarized as
> The previous example showed that the type system forbids any borrowing of owned boxes found in aliasable, mutable memory.
This did not jive with the example, which allowed mutations so long as the borrowed reference had been returned. Also, the language has changed to no longer allow aliasable mutable locations. This changes the summary to read
> The previous example showed that the type system forbids mutations of owned boxed values while they are being borrowed. In general, the type system also forbids borrowing a value as mutable if it is already being borrowed - either as a mutable reference or an immutable one.
This adds more general information for the experienced reader as well, to offer a more complete understanding.

The guide previously stated:
> The compiler will automatically convert a box box point to a reference like &point.
This fixes the doubled word `box`, so the statement reads
> The compiler will automatically convert a box point to a reference like &point.
The code it is referring to is `compute_distance(&on_the_stack, on_the_heap);`, so a single `box` is appropriate.

Now that rustdoc understands proper language tags
as the code not being Rust, we can tag everything
properly.
This change tags examples in other languages by
their language. Plain notations are marked as `text`.
Console examples are marked as `console`.
Also fix markdown.rs to not highlight non-rust code.
|
|
This rewrites the example to also be more aligned with
the same example given in the main tutorial.

for `~str`/`~[]`.
Note that `~self` still remains, since I forgot to add support for
`Box<self>` before the snapshot.
How to update your code:
* Instead of `~EXPR`, you should write `box EXPR`.
* Instead of `~TYPE`, you should write `Box<Type>`.
* Instead of `~PATTERN`, you should write `box PATTERN`.

- Use Fira Sans for headlines, Heuristica for the body (Adobe Utopia derivative). Both are licensed under the SIL OFL license. (I didn't include BoldItalic because it is sparingly used.)
- Split TOC into 2 columns for the docs except manual (too tall, too wide to be readable).
- Some fixes to rustdoc, bring styles in coherency with eachother
- A few tweaks
Two examples: [modified tutorial](http://adrientetar.legtux.org/cached/rust-docs/tutorial.htm) and [modified manual](http://adrientetar.legtux.org/cached/rust-docs/manual.htm).
Rustdoc got some fixes, here is [modified `enum.FileType`](http://adrientetar.legtux.org/cached/rust-docs/enum.FileType.htm), [modified `std`](http://adrientetar.legtux.org/cached/rust-docs/std.htm) and [modified `std::io`](http://adrientetar.legtux.org/cached/rust-docs/io.htm).

* Note on while loop not supporting named breaks.
* Note on hygienic macros (and example of such within loops)
|
|
* Include tip given by Leo Testard in mailing list about labeled `break`
and `continue`:
https://mail.mozilla.org/pipermail/rust-dev/2014-March/009145.html
* cross-reference named lifetimes in tutorial -> lifetimes guide
* Broke named lifetimes section into two sub-sections.
* Added mention of `'static` lifetime.

The changes are basically just because rustdoc runs tests/rendering on
more snippets by default (i.e. everything without a `notrust` tag), and
not anything significant.
|
|
We generate documentation into the doc/ directory, so we shouldn't be
intermingling source files with generated files
