Version 1.40.0 (2019-12-19)
|
||||||
|
===========================
|
||||||
|
|
||||||
|
Language
|
||||||
|
--------
|
||||||
|
- [You can now use tuple `struct`s and tuple `enum` variant's constructors in
|
||||||
|
`const` contexts.][65188] e.g.
|
||||||
|
|
||||||
|
```rust
|
||||||
|
pub struct Point(i32, i32);
|
||||||
|
|
||||||
|
const ORIGIN: Point = {
|
||||||
|
let constructor = Point;
|
||||||
|
|
||||||
|
constructor(0, 0)
|
||||||
|
};
|
||||||
|
```
|
||||||
|
|
||||||
|
- [You can now mark `struct`s, `enum`s, and `enum` variants with the `#[non_exhaustive]` attribute to
|
||||||
|
indicate that there may be variants or fields added in the future.][64639]
|
||||||
|
For example this requires adding a wild-card branch (`_ => {}`) to any match
|
||||||
|
statements on a non-exhaustive `enum`. [(RFC 2008)]
|
||||||
|
- [You can now use function-like procedural macros in `extern` blocks and in
|
||||||
|
type positions.][63931] e.g. `type Generated = macro!();`
|
||||||
|
- [Function-like and attribute procedural macros can now emit
|
||||||
|
`macro_rules!` items, so you can now have your macros generate macros.][64035]
|
||||||
|
- [The `meta` pattern matcher in `macro_rules!` now correctly matches the modern
|
||||||
|
attribute syntax.][63674] For example `(#[$m:meta])` now matches `#[attr]`,
|
||||||
|
`#[attr{tokens}]`, `#[attr[tokens]]`, and `#[attr(tokens)]`.
|
||||||
|
|
||||||
|
Compiler
|
||||||
|
--------
|
||||||
|
- [Added tier 3 support\* for the
|
||||||
|
`thumbv7neon-unknown-linux-musleabihf` target.][66103]
|
||||||
|
- [Added tier 3 support for the
|
||||||
|
`aarch64-unknown-none-softfloat` target.][64589]
|
||||||
|
- [Added tier 3 support for the `mips64-unknown-linux-muslabi64`, and
|
||||||
|
`mips64el-unknown-linux-muslabi64` targets.][65843]
|
||||||
|
|
||||||
|
\* Refer to Rust's [platform support page][forge-platform-support] for more
|
||||||
|
information on Rust's tiered platform support.
|
||||||
|
|
||||||
|
Libraries
|
||||||
|
---------
|
||||||
|
- [The `is_power_of_two` method on unsigned numeric types is now a `const` function.][65092]
|
||||||
|
|
||||||
|

Cargo
|
||||||
|
-----
|
||||||
|
- [Cargo will now always display warnings, rather than only on
|
||||||
|
fresh builds.][cargo/7450]
|
||||||
|
- [Feature flags (except `--all-features`) passed to a virtual workspace will
|
||||||
|
now produce an error.][cargo/7507] Previously these flags were ignored.
|
||||||
|
- [You can now publish `dev-dependencies` without including
|
||||||
|
a `version`.][cargo/7333]
|
||||||
|
|
||||||
|
Misc
|
||||||
|
----
|
||||||
|
- [You can now specify the `#[cfg(doctest)]` attribute to include an item only
|
||||||
|
when running documentation tests with `rustdoc`.][63803]
|
||||||
|
|
||||||
|
Compatibility Notes
|
||||||
|
-------------------
|
||||||
|
- [As previously announced, any previous NLL warnings in the 2015 edition are
|
||||||
|
now hard errors.][64221]
|
||||||
|
- [The `include!` macro will now warn if it failed to include the
|
||||||
|
entire file.][64284] The `include!` macro unintentionally only includes the
|
||||||
|
first _expression_ in a file, and this can be unintuitive. This will become
|
||||||
|
a hard error in a future release.
|
||||||
|
- [Using `#[inline]` on function prototypes and consts now emits a warning under
|
||||||
|
`unused_attribute` lint.][65294] Using `#[inline]` anywhere else inside traits
|
||||||
|
or `extern` blocks now correctly emits a hard error.
