- Update to version 1.32.0
- Language
  + 2018 edition
    - You can now use the `?` operator in macro definitions. The `?`
      operator allows you to specify zero or one repetitions similar to the `*` and
      `+` operators.
    - Module paths with no leading keyword like `super`, `self`, or `crate`, will
      now always resolve to the item (`enum`, `struct`, etc.) available in the
      module if present, before resolving to a external crate or an item the prelude.
      E.g.
      enum Color { Red, Green, Blue }
      use Color::*;
  + All editions
    - You can now match against `PhantomData<T>` types.
    - You can now match against literals in macros with the `literal`
      specifier. 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 for unit and tuple structs. E.g.
      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. E.g.
      enum List<T>
      where
          Self: PartialOrd<Self> // can write `Self` instead of `List<T>`
      {
          Nil,
          Cons(T, Box<Self>) // likewise here
      }
    - You can now mark traits with `#[must_use]`. This provides a warning if
      a `impl Trait` or `dyn Trait` is returned and unused in the program.
- Compiler
  + The default allocator has changed from jemalloc to the default allocator on
    your system. The compiler itself on Linux & macOS will still use
    jemalloc, but programs compiled with it will use the system allocator.
  + Added the `aarch64-pc-windows-msvc` target.
- Libraries
  + `PathBuf` now implements `FromStr`.
  - `Box<[T]>` now implements `FromIterator<T>`.
  - The `dbg!` macro has been stabilized. This macro enables you to
    easily debug expressions in your rust program. E.g.
    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`
    - `char::is_ascii`
    - `iter::empty`
    - `ManuallyDrop::new`

    - `RangeInclusive::start`

    - `Duration::as_secs`
    - `Duration::subsec_millis`
    - `Duration::subsec_micros`

    - `CStr::as_ptr`
    - `Ipv4Addr::is_unspecified`
    - `Ipv6Addr::new`
    - `Ipv6Addr::octets`
