1639e51f6e Feature gate *all* slice patterns. #23121
Until some backwards-compatibility hazards are fixed in #23121,
these need to be unstable.

95602a759d Add trivial cast lints.
This permits all coercions to be performed in casts, but adds lints to warn in those cases.

Part of this patch moves cast checking to a later stage of type checking. We acquire obligations to check casts as part of type checking where we previously checked them. Once we have type checked a function or module, then we check any cast obligations which have been acquired. That means we have more type information available to check casts (this was crucial to making coercions work properly in place of some casts), but it means that casts cannot feed input into type inference.

[breaking change]

* Adds two new lints for trivial casts and trivial numeric casts, these are warn by default, but can cause errors if you build with warnings as errors. Previously, trivial numeric casts and casts to trait objects were allowed.
* The unused casts lint has gone.
* Interactions between casting and type inference have changed in subtle ways. Two ways this might manifest are:
- You may need to 'direct' casts more with extra type information, for example, in some cases where `foo as _ as T` succeeded, you may now need to specify the type for `_`
- Casts do not influence inference of integer types. E.g., the following used to type check:

```
let x = 42;
let y = &x as *const u32;
```

Because the cast would inform inference that `x` must have type `u32`. This no longer applies and the compiler will fallback to `i32` for `x` and thus there will be a type error in the cast. The solution is to add more type information:

```
let x: u32 = 42;
let y = &x as *const u32;
```

76ead08108 Remove auto-deref'ing Pattern impl because it conflicts with other
possible blanket impls and also triggers internal overflow. Add some
special cases for common uses (&&str, &String) for now; bounds-targeting
deref coercions are probably the right longer term answer.

212e03181e std: Remove old_io/old_path from the prelude
This commit removes the reexports of `old_io` traits as well as `old_path` types
and traits from the prelude. This functionality is now all deprecated and needs
to be removed to make way for other functionality like `Seek` in the `std::io`
module (currently reexported as `NewSeek` in the io prelude).

cfea8ec416 Auto merge of #23126 - alexcrichton:char-third-pass, r=aturon
This commit performs another pass over the `std::char` module for stabilization.
Some minor cleanup is performed such as migrating documentation from libcore to
libunicode (where the `std`-facing trait resides) as well as a slight
reorganiation in libunicode itself. Otherwise, the stability modifications made
are:

* `char::from_digit` is now stable
* `CharExt::is_digit` is now stable
* `CharExt::to_digit` is now stable
* `CharExt::to_{lower,upper}case` are now stable after being modified to return
  an iterator over characters. While the implementation today has not changed
  this should allow us to implement the full set of case conversions in unicode
  where some characters can map to multiple when doing an upper or lower case
  mapping.
* `StrExt::to_{lower,upper}case` was added as unstable for a convenience of not
  having to worry about characters expanding to more characters when you just
  want the whole string to get into upper or lower case.

This is a breaking change due to the change in the signatures of the
`CharExt::to_{upper,lower}case` methods. Code can be updated to use functions
like `flat_map` or `collect` to handle the difference.

0d5bcb14ad Switched to Box::new in many places.
Many of the modifications putting in `Box::new` calls also include a
pointer to Issue 22405, which tracks going back to `box <expr>` if
possible in the future.

(Still tried to use `Box<_>` where it sufficed; thus some tests still
have `box_syntax` enabled, as they use a mix of `box` and `Box::new`.)

Precursor for overloaded-`box` and placement-`in`; see Issue 22181.

270f0eef73 Add : Box<_> or ::Box<_> type annotations to various places.
This is the kind of change that one is expected to need to make to
accommodate overloaded-`box`.

----

Note that this is not *all* of the changes necessary to accommodate
Issue 22181.  It is merely the subset of those cases where there was
already a let-binding in place that made it easy to add the necesasry
type ascription.

(For unnamed intermediate `Box` values, one must go down a different
route; `Box::new` is the option that maximizes portability, but has
potential inefficiency depending on whether the call is inlined.)

----

There is one place worth note, `run-pass/coerce-match.rs`, where I
used an ugly form of `Box<_>` type ascription where I would have
preferred to use `Box::new` to accommodate overloaded-`box`.  I
deliberately did not use `Box::new` here, because that is already done
in coerce-match-calls.rs.

c8db89aa82 Accommodate arith-overflow in core::num, std::num, coretest::num.
* `core::num`: adjust `UnsignedInt::is_power_of_two`,
   `UnsignedInt::next_power_of_two`, `Int::pow`.

   In particular for `Int::pow`: (1.) do not panic when `base`
   overflows if `acc` never observes the overflowed `base`, and (2.)
   if `acc` does observe the overflowed `base`, make sure we only
   panic if we would have otherwise (e.g. during a computation of
   `base * base`).

 * also in `core::num`: avoid underflow during computation of `uint::MAX`.

 * `std::num`: adjust tests `uint::test_uint_from_str_overflow`,
   `uint::test_uint_to_str_overflow`, `strconv`

 * `coretest::num`: adjust `test::test_int_from_str_overflow`.

4f61e16032 Fix std::ops::Range size_hint and ExactSizeIterator impls
When self.start > self.end, these iterators simply return None,
so we adjust the size_hint to just return zero in this case.

Certain optimizations can be implemented in and outside libstd if we
know we can trust the size_hint for all inputs to for example
Range<usize>.

This corrects the ExactSizeIterator implementations, which IMO were
unsound and incorrect previously, since they allowed a range like (2..1)
to return a size_hint of -1us in when debug assertions are turned off.

df1ac7aa63 Deprecate in-tree rand, std::rand and #[derive(Rand)].
Use the crates.io crate `rand` (version 0.1 should be a drop in
replacement for `std::rand`) and `rand_macros` (`#[derive_Rand]` should
be a drop-in replacement).

87eb67f4f0 rollup merge of #21854: alexcrichton/try-borrow
The existence of these two functions is at odds with our current [error
conventions][conventions] which recommend that panicking and `Result`-like
variants should not be provided together.

[conventions]: https://github.com/rust-lang/rfcs/blob/master/text/0236-error-conventions.md#do-not-provide-both-result-and-fail-variants

This commit adds a new `borrow_state` function returning a `BorrowState` enum to
`RefCell` which serves as a replacemnt for the `try_borrow` and `try_borrow_mut`
functions.

ac1a03d742 rollup merge of #21718: alexcrichton/stabilize-from-str
This commits adds an associated type to the `FromStr` trait representing an
error payload for parses which do not succeed. The previous return value,
`Option<Self>` did not allow for this form of payload. After the associated type
was added, the following attributes were applied:

* `FromStr` is now stable
* `FromStr::Err` is now stable
* `FromStr::from_str` is now stable
* `StrExt::parse` is now stable
* `FromStr for bool` is now stable
* `FromStr for $float` is now stable
* `FromStr for $integral` is now stable
* Errors returned from stable `FromStr` implementations are stable
* Errors implement `Display` and `Error` (both impl blocks being `#[stable]`)

Closes #15138

5d836cdf86 std: Rename Writer::write to Writer::write_all
In preparation for upcoming changes to the `Writer` trait (soon to be called
`Write`) this commit renames the current `write` method to `write_all` to match
the semantics of the upcoming `write_all` method. The `write` method will be
repurposed to return a `usize` indicating how much data was written which
differs from the current `write` semantics. In order to head off as much
unintended breakage as possible, the method is being deprecated now in favor of
a new name.
