This PR uses the inline error suggestions introduced in #24242 to modify a few existing `help` messages. The new errors look like this:
foobar.rs:5:12: 5:25 error: expected a path on the left-hand side of `+`,
not `&'static Copy` [E0178]
foobar.rs:5 let x: &'static Copy + 'static;
^~~~~~~~~~~~~
foobar.rs:5:12: 5:35 help: try adding parentheses (per RFC 438):
foobar.rs: let x: &'static (Copy + 'static);
foobar.rs:2:13: 2:23 error: cast to unsized type: `&_` as `core::marker::Copy`
foobar.rs:2 let x = &1 as Copy;
^~~~~~~~~~
foobar.rs:2:19: 2:23 help: try casting to a reference instead:
foobar.rs: let x = &1 as &Copy;
foobar.rs:7:24: 7:25 error: expected expression, found `;`
foobar.rs:7 let x = box (1 + 1);
^
foobar.rs:7:13: 7:16 help: try using `box()` instead:
foobar.rs: let x = box() (1 + 1);
This also modifies compiletest to give the ability to directly test suggestions given by error messages.

PR #24242 added the ability to the compiler to directly give suggestions about
how to modify code to fix an error. The new errors look like this:

not `&'static Copy` [E0178]

Previously 0b12 was considered two tokens, 0b1 and 2, as 2 isn't a valid
base 2 digit. This patch changes that to collapse them into one (and
makes `0b12` etc. an error: 2 isn't a valid base 2 digit).
This may break some macro invocations of macros with `tt` (or syntax
extensions) that rely on adjacent digits being separate tokens and hence
is a
[breaking-change]
The fix is to separate the tokens, e.g. `0b12` -> `0b1 2`.

The compiler will now issue a warning for crates that have syntax of the form
`extern crate "foo" as bar`, but it will still continue to accept this syntax.
Additionally, the string `foo-bar` will match the crate name `foo_bar` to assist
in the transition period as well.
This patch will land hopefully in tandem with a Cargo patch that will start
translating all crate names to have underscores instead of hyphens.

* no_split_stack was renamed to no_stack_check
* deriving was renamed to derive
* `use foo::mod` was renamed to `use foo::self`;
* legacy lifetime definitions in closures have been replaced with `for` syntax
* `fn foo() -> &A + B` has been deprecated for some time (needs parens)
* Obsolete `for Sized?` syntax
* Obsolete `Sized? Foo` syntax
* Obsolete `|T| -> U` syntax

[breaking-change]: instead of a closure like `|| -> i32 22`, prefer `||
-> i32 { 22 }`.
Fixes #23420.

passing the latter around.

The end result is that common fields (id, name, attributes, etc.) are stored in now-structures `ImplItem` and `TraitItem`.
The signature of a method is no longer duplicated between methods with a body (default/impl) and those without, they now share `MethodSig`.
This is also a [breaking-change] because of minor bugfixes and changes to syntax extensions:
* `pub fn` methods in a trait no longer parse - remove the `pub`, it has no meaning anymore
* `MacResult::make_methods` is now `make_impl_items` and the return type has changed accordingly
* `quote_method` is gone, because `P<ast::Method>` doesn't exist and it couldn't represent a full method anyways - could be replaced by `quote_impl_item`/`quote_trait_item` in the future, but I do hope we realize how silly that combinatorial macro expansion is and settle on a single `quote` macro + some type hints - or just no types at all (only token-trees)
r? @nikomatsakis This is necessary (hopefully also sufficient) for associated constants.

These have been deprecated for quite some time, so we should be good to remove
them now.
|
|
|

This commit deprecates the majority of std::old_io::fs in favor of std::fs and
its new functionality. Some functions remain non-deprecated but are now behind a
feature gate called `old_fs`. These functions will be deprecated once
suitable replacements have been implemented.
The compiler has been migrated to new `std::fs` and `std::path` APIs where
appropriate as part of this change.

r? @aturon
Fixes #22478. The underlying bug(?) behind that issue still exists though and there’s another issue that reports it.
