- Update to version 1.31.0
+ Language
- This version marks the release of the 2018 edition of Rust.
- New lifetime elision rules now allow for eliding lifetimes in functions and
impl headers. E.g. `impl<'a> Reader for BufReader<'a> {}` can now be
`impl Reader for BufReader<'_> {}`. Lifetimes are still required to be defined
in structs.
- You can now define and use `const` functions. These are currently
a strict minimal subset of the const fn RFC. Refer to the
[language reference][const-reference] for what exactly is available.
- You can now use tool lints, which allow you to scope lints from external
tools using attributes. E.g. `#[allow(clippy::filter_map)]`.
- `#[no_mangle]` and `#[export_name]` attributes can now be located anywhere in
a crate, not just in exported functions.
- You can now use parentheses in pattern matches.
+ Compiler
- Updated musl to 1.1.20
+ Libraries
- You can now convert `num::NonZero*` types to their raw equivalvents using the
`From` trait. E.g. `u8` now implements `From<NonZeroU8>`.
- You can now convert a `&Option<T>` into `Option<&T>` and `&mut Option<T>`
into `Option<&mut T>` using the `From` trait.
- You can now multiply (`*`) a `time::Duration` by a `u32`.
+ Stabilized APIs
- `slice::align_to`
- `slice::align_to_mut`
- `slice::chunks_exact`
- `slice::chunks_exact_mut`
- `slice::rchunks`
- `slice::rchunks_mut`
- `slice::rchunks_exact`
- `slice::rchunks_exact_mut`
- `Option::replace`
+ Cargo
- Cargo will now download crates in parallel using HTTP/2.
- You can now rename packages in your Cargo.toml We have a guide
on how to use the `package` key in your dependencies.
