- Remove `()` parens when referencing functions in docs.
- Change some examples to be no_run instead of ignore.
- Normalize style in examples for `OpenOptionsExt`.
- Fix typo in windows mod docs.
* Use a different loop variable, `i` was already taken. This caused
missing items in the implementors list.
* Use `.getAttribute('href')` rather than `.href` to get the relative
URL which is what it needs to actually fix the links.
Previously, any non-Unicode argument would panic rustc:
```
$ rustc $'foo\x80bar'
error: internal compiler error: unexpected panic
note: the compiler unexpectedly panicked. this is a bug.
note: we would appreciate a bug report:
https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports
thread 'rustc' panicked at 'called `Result::unwrap()` on an `Err` value:
"foo�bar"', /checkout/src/libcore/result.rs:859 note: Run with
`RUST_BACKTRACE=1` for a backtrace.
```
Now it gives a clean error:
```
$ rustc $'foo\x80bar'
error: Argument 1 is not valid Unicode: "foo�bar"
```
Maybe fixes#15890, although we still can't *compile* arbitrary file names.

Enable cross-crate incremental compilation by default.
Now that direct metadata hashing has been implemented for a while and we haven't seen any problems with it over at [rust-icci](https://travis-ci.org/rust-icci/), let's re-enable cross crate support for incremental compilation again.

Unify tools building
Close#41601
Time saving for up to 10 minutes. Cargo is now only compiled once.
Downsides:
- Out of tree Cargo.lock maintenance
- Cargo.toml `[replace]` version maintenance
Remove interior mutability from TraitDef by turning fields into queries
This PR gets rid of anything `std::cell` in `TraitDef` by
- moving the global list of trait impls from `TraitDef` into a query,
- moving the list of trait impls relevent for some self-type from `TraitDef` into a query
- moving the specialization graph of trait impls into a query, and
- moving `TraitDef::object_safety` into a query.
I really like how querifying things not only helps with incremental compilation and on-demand, but also just plain makes the code cleaner `:)`
There are also some smaller fixes in the PR. Commits can be reviewed separately.
r? @eddyb or @nikomatsakis
This avoids double compiled Cargo. Hopefully this would speed up (extended) compilation for ~10m.
Notes: when updating Cargo submodule, the replacement version may also need to be updated.
Fix#35829 (`quote!()` does not handle `br#"…"#`)
Fix issue #35829 (syntax extension's `quote_expr!()` does not handle `b"…"` and proc_macro's `quote!()` does not handle `r#"…"#`)
* Handles `b"…"`, `br#"…"#` and `...` for `quote_expr!()`.
* Refactored the match statement to allow it to complain loudly on any unhandled token.
* Similarly, proc_macro's `quote!()` did not handle `br#"…"#` or `r#"…"#`, so this PR fixes it too.
Document the `proc_macro` feature in the Unstable Book
Discusses the `proc_macro` feature flag and the features it enables:
* Implicit enable of `extern_use_macros` feature and how to import proc macros
* Error handling in proc macros (using panic messages)
* Function-like proc macros using `#[proc_macro]` and a usage example for creating and invoking
* Attribute-like proc macros using `#[proc_macro_attribute]` and a usage example for creating and invoking

Update cargo submodule
This pulls in a fix for #41797 to the master branch, I'll send a separate PR for
the beta branch. Note that the Cargo PR in question to pull in is https://github.com/rust-lang/cargo/pull/4046
