The reason this was not failing is fascinating. The variable $(rustc)
is empty, so the make recipe was expanded as " -o foo foo.rs". make
interpreted this as an instruction to run the command "o foo foo.rs"
and ignore any failure that occurred, because it uses a leading '-' on
a command to signal that behavior.
"Rust Inside Other Languages" in the Rust book includes a library example. The reference specifies printing "done!" when the code finishes running, and the language examples (Ruby, Python, JS) all do this in their code.
However, the Rust library example code *also* does this, so that the examples as written would output "done!" twice.
This commit removes the "done!" from the Rust example code to tidy up the output to match expectations.

By RFC1214:
> Before calling a fn, we check that its argument and return types are WF.
The previous code only checked the trait-ref, which was not enough
in several cases.
As this is a soundness fix, it is a [breaking-change]. Some new annotations are needed, which I think are because of #18653 and the imperfection of `projection_must_outlive` (that can probably be worked around by moving the wf obligation later).
Fixes#28609

libcore.rlib reduced from 19121 kiB to 15934 kiB - 20% win.
The librustc encoded AST is 9013500 bytes long - for the record, librustc consists of about 2254126 characters. Might be worth looking at.

This adds a paragraph on how to generate documentation without sloooow `make doc`. I'm not a native English speaker, so there might be some language related bugs (I wish English was as hard to get wrong, as Rust)
This also includes whitespace cleanup of contributing.md in a separate commit. Whiltespace is not significant in github flavored markdown, and my Emacs just cleans ws automatically :)

Our docs were very basic for the various versions of from_utf8, so
this commit beefs them up.
It also improves docs for the &str variant's error, Utf8Error.

By RFC1214:
Before calling a fn, we check that its argument and return types are WF. This check takes place after all higher-ranked lifetimes have been instantiated. Checking the argument types ensures that the implied bounds due to argument types are correct. Checking the return type ensures that the resulting type of the call is WF.
The previous code only checked the trait-ref, which was not enough
in several cases.
As this is a soundness fix, it is a [breaking-change].

This PR closes out #28716 and #28735 by making two changes to the compiler:
1. The `--emit` flag to the compiler now supports the ability to specify the output file name of a partuclar emit type. For example `--emit dep-info=bar.d,asm=foo.s,link` is now accepted.
2. The dep-info emission now emits a dummy target for all input file names to protect against deleted files.
These common traits were left off originally by accident from these smart
pointers, and a past attempt (#26008) to add them was later reverted (#26160)
due to unexpected breakge (#26096) occurring. The specific breakage in worry is
the meaning of this return value changed:
let a: Box<Option<T>> = ...;
a.as_ref()
Currently this returns `Option<&T>` but after this change it will return
`&Option<T>` because the `AsRef::as_ref` method shares the same name as
`Option::as_ref`. A [crater report][crater] of this change, however, has shown
that the fallout of this change is quite minimal. These trait implementations
are "the right impls to add" to these smart pointers and would enable various
generalizations such as those in #27197.
[crater]: https://gist.github.com/anonymous/0ba4c3512b07641c0f99
This commit is a breaking change for the above reasons mentioned, and the
mitigation strategies look like any of:
Option::as_ref(&a)
a.as_ref().as_ref()
(*a).as_ref()
Previously only keyup event was looked at, which meant that pasting, cutting and
otherwise changing the input without typing would not catch any updates to the
search query.
