Version 1.32.0 (2019-01-17)
|
||||
==========================
|
||||
|
||||
Language
|
||||
--------
|
||||
#### 2018 edition
|
||||
- [You can now use the `?` operator in macro definitions.][56245] The `?`
|
||||
operator allows you to specify zero or one repetitions similar to the `*` and
|
||||
`+` operators.
|
||||
|
||||
#### All editions
|
||||
- [You can now match against `PhantomData<T>` types.][55837]
|
||||
- [You can now match against literals in macros with the `literal`
|
||||
specifier.][56072] This will match against a literal of any type.
|
||||
E.g. `1`, `'A'`, `"Hello World"`
|
||||
- [Self can now be used as a constructor and pattern.][56365] E.g.
|
||||
```rust
|
||||
struct Point(i32, i32);
|
||||
|
||||
impl Point {
|
||||
pub fn new(x: i32, y: i32) -> Self {
|
||||
Self(x, y)
|
||||
}
|
||||
|
||||
pub fn is_origin(&self) -> bool {
|
||||
match self {
|
||||
Self(0, 0) => true,
|
||||
_ => false,
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
- [Self can also now be used in type definitions.][56366] E.g.
|
||||
```rust
|
||||
enum List<T>
|
||||
where
|
||||
Self: PartialOrd<Self> // can write `Self` instead of `List<T>`
|
||||
{
|
||||
Nil,
|
||||
Cons(T, Box<Self>) // likewise here
|
||||
}
|
||||
```
|
||||
|
||||
Compiler
|
||||
--------
|
||||
- [You can now mark traits with `#[must_use]`.][55663] Providing a warning if
|
||||
they unused in a program.
|
||||
- [The default allocator has changed from jemalloc to the default allocator on
|
||||
your system.][55238] The compiler itself on Linux & macOS will still use
|
||||
jemalloc, but programs compiled with them will use the system allocator.
|
||||
- [Added the `aarch64-pc-windows-msvc` target.][55702]
|
||||
|
||||
Libraries
|
||||
---------
|
||||
- [`PathBuf` now implements `FromStr`.][55148]
|
||||
- [`Box<[T]>` now implements `FromIterator<T>`.][55843]
|
||||
- [The `dbg!` macro has been stabilized.][56395] This macro enables you to
|
||||
easily debug expressions in your rust program. E.g.
|
||||
```rust
|
||||
let a = 2;
|
||||
let b = dbg!(a * 2) + 1;
|
||||
// ^-- prints: [src/main.rs:4] a * 2 = 4
|
||||
assert_eq!(b, 5);
|
||||
```
|
||||
|
||||
The following APIs are now `const` functions and can be used in a
|
||||
`const` context.
|
||||
|
||||
- [`Cell::as_ptr`]
|
||||
- [`UnsafeCell::get`]
|
||||

Compatibility Notes
|
||||
-------------------
|
||||
- [The argument types for AVX's
|
||||
`_mm256_stream_si256`, `_mm256_stream_pd`, `_mm256_stream_ps`][55610] have
|
||||
been changed from `*const` to `*mut` as the previous implementation
|
||||
was unsound.
