Changelog: 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. - [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.][56759] E.g. ```rust enum Color { Red, Green, Blue } use Color::*; ``` #### 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 for unit and tuple structs.][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 } ``` - [You can now mark traits with `#[must_use]`.][55663] 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.][55238] 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.][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`] - [`char::is_ascii`] - [`iter::empty`] - [`ManuallyDrop::new`] - [`ManuallyDrop::into_inner`] - [`RangeInclusive::start`] - [`RangeInclusive::end`] - [`NonNull::as_ptr`] - [`slice::as_ptr`] - [`str::as_ptr`] - [`Duration::as_secs`] - [`Duration::subsec_millis`] - [`Duration::subsec_micros`] - [`Duration::subsec_nanos`] - [`CStr::as_ptr`] - [`Ipv4Addr::is_unspecified`] - [`Ipv6Addr::new`] - [`Ipv6Addr::octets`] Stabilized APIs --------------- - [`i8::to_be_bytes`] - [`i8::to_le_bytes`] - [`i8::to_ne_bytes`] - [`i8::from_be_bytes`] - [`i8::from_le_bytes`] - [`i8::from_ne_bytes`] - [`i16::to_be_bytes`] - [`i16::to_le_bytes`] - [`i16::to_ne_bytes`] - [`i16::from_be_bytes`] - [`i16::from_le_bytes`] - [`i16::from_ne_bytes`] - [`i32::to_be_bytes`] - [`i32::to_le_bytes`] - [`i32::to_ne_bytes`] - [`i32::from_be_bytes`] - [`i32::from_le_bytes`] - [`i32::from_ne_bytes`] - [`i64::to_be_bytes`] - [`i64::to_le_bytes`] - [`i64::to_ne_bytes`] - [`i64::from_be_bytes`] - [`i64::from_le_bytes`] - [`i64::from_ne_bytes`] - [`i128::to_be_bytes`] - [`i128::to_le_bytes`] - [`i128::to_ne_bytes`] - [`i128::from_be_bytes`] - [`i128::from_le_bytes`] - [`i128::from_ne_bytes`] - [`isize::to_be_bytes`] - [`isize::to_le_bytes`] - [`isize::to_ne_bytes`] - [`isize::from_be_bytes`] - [`isize::from_le_bytes`] - [`isize::from_ne_bytes`] - [`u8::to_be_bytes`] - [`u8::to_le_bytes`] - [`u8::to_ne_bytes`] - [`u8::from_be_bytes`] - [`u8::from_le_bytes`] - [`u8::from_ne_bytes`] - [`u16::to_be_bytes`] - [`u16::to_le_bytes`] - [`u16::to_ne_bytes`] - [`u16::from_be_bytes`] - [`u16::from_le_bytes`] - [`u16::from_ne_bytes`] - [`u32::to_be_bytes`] - [`u32::to_le_bytes`] - [`u32::to_ne_bytes`] - [`u32::from_be_bytes`] - [`u32::from_le_bytes`] - [`u32::from_ne_bytes`] - [`u64::to_be_bytes`] - [`u64::to_le_bytes`] - [`u64::to_ne_bytes`] - [`u64::from_be_bytes`] - [`u64::from_le_bytes`] - [`u64::from_ne_bytes`] - [`u128::to_be_bytes`] - [`u128::to_le_bytes`] - [`u128::to_ne_bytes`] - [`u128::from_be_bytes`] - [`u128::from_le_bytes`] - [`u128::from_ne_bytes`] - [`usize::to_be_bytes`] - [`usize::to_le_bytes`] - [`usize::to_ne_bytes`] - [`usize::from_be_bytes`] - [`usize::from_le_bytes`] - [`usize::from_ne_bytes`] Cargo ----- - [You can now run `cargo c` as an alias for `cargo check`.][cargo/6218] - [Usernames are now allowed in alt registry URLs.][cargo/6242] Misc ---- - [`libproc_macro` has been added to the `rust-src` distribution.][55280] 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.

RoelKluin · 2019-01-22T21:12:54Z

I wonder whether this alternative implementation that optionally allows formatting may be of use:
#54317 (comment)

Centril · 2019-01-22T21:18:20Z

@RoelKluin you might want to raise this issue somewhere more visible for new discussion, e.g. http://internals.rust-lang.org/.

My view is that extra arguments should be for passing more values, that no guarantees should be made about formatting, and that formatting choices is better served by a different macro. You may try out the more advanced macro in https://crates.io/crates/dbg.

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`] - [`char::is_ascii`] - [`iter::empty`] - [`ManuallyDrop::new`] - [`ManuallyDrop::into_inner`] - [`RangeInclusive::start`] - [`RangeInclusive::end`] - [`NonNull::as_ptr`] - [`slice::as_ptr`] - [`str::as_ptr`] - [`Duration::as_secs`] - [`Duration::subsec_millis`] - [`Duration::subsec_micros`] - [`Duration::subsec_nanos`] - [`CStr::as_ptr`] - [`Ipv4Addr::is_unspecified`] - [`Ipv6Addr::new`] - [`Ipv6Addr::octets`] Stabilized APIs --------------- - [`i8::to_be_bytes`] - [`i8::to_le_bytes`] - [`i8::to_ne_bytes`] - [`i8::from_be_bytes`] - [`i8::from_le_bytes`] - [`i8::from_ne_bytes`] - [`i16::to_be_bytes`] - [`i16::to_le_bytes`] - [`i16::to_ne_bytes`] - [`i16::from_be_bytes`] - [`i16::from_le_bytes`] - [`i16::from_ne_bytes`] - [`i32::to_be_bytes`] - [`i32::to_le_bytes`] - [`i32::to_ne_bytes`] - [`i32::from_be_bytes`] - [`i32::from_le_bytes`] - [`i32::from_ne_bytes`] - [`i64::to_be_bytes`] - [`i64::to_le_bytes`] - [`i64::to_ne_bytes`] - [`i64::from_be_bytes`] - [`i64::from_le_bytes`] - [`i64::from_ne_bytes`] - [`i128::to_be_bytes`] - [`i128::to_le_bytes`] - [`i128::to_ne_bytes`] - [`i128::from_be_bytes`] - [`i128::from_le_bytes`] - [`i128::from_ne_bytes`] - [`isize::to_be_bytes`] - [`isize::to_le_bytes`] - [`isize::to_ne_bytes`] - [`isize::from_be_bytes`] - [`isize::from_le_bytes`] - [`isize::from_ne_bytes`] - [`u8::to_be_bytes`] - [`u8::to_le_bytes`] - [`u8::to_ne_bytes`] - [`u8::from_be_bytes`] - [`u8::from_le_bytes`] - [`u8::from_ne_bytes`] - [`u16::to_be_bytes`] - [`u16::to_le_bytes`] - [`u16::to_ne_bytes`] - [`u16::from_be_bytes`] - [`u16::from_le_bytes`] - [`u16::from_ne_bytes`] - [`u32::to_be_bytes`] - [`u32::to_le_bytes`] - [`u32::to_ne_bytes`] - [`u32::from_be_bytes`] - [`u32::from_le_bytes`] - [`u32::from_ne_bytes`] - [`u64::to_be_bytes`] - [`u64::to_le_bytes`] - [`u64::to_ne_bytes`] - [`u64::from_be_bytes`] - [`u64::from_le_bytes`] - [`u64::from_ne_bytes`] - [`u128::to_be_bytes`] - [`u128::to_le_bytes`] - [`u128::to_ne_bytes`] - [`u128::from_be_bytes`] - [`u128::from_le_bytes`] - [`u128::from_ne_bytes`] - [`usize::to_be_bytes`] - [`usize::to_le_bytes`] - [`usize::to_ne_bytes`] - [`usize::from_be_bytes`] - [`usize::from_le_bytes`] - [`usize::from_ne_bytes`] Cargo ----- - [You can now run `cargo c` as an alias for `cargo check`.][cargo/6218] - [Usernames are now allowed in alt registry URLs.][cargo/6242] Misc ---- - [`libproc_macro` has been added to the `rust-src` distribution.][55280] 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.
