Version 1.51.0 (2021-03-25)
|
||||
============================
|
||||
|
||||
Language
|
||||
--------
|
||||
- [You can now parameterize items such as functions, traits, and `struct`s by constant
|
||||
values in addition to by types and lifetimes.][79135] Also known as "const generics"
|
||||
E.g. you can now write the following. Note: Only values of primitive integers,
|
||||
`bool`, or `char` types are currently permitted.
|
||||
```rust
|
||||
struct GenericArray<T, const LENGTH: usize> {
|
||||
inner: [T; LENGTH]
|
||||
}
|
||||
|
||||
impl<T, const LENGTH: usize> GenericArray<T, LENGTH> {
|
||||
const fn last(&self) -> Option<&T> {
|
||||
if LENGTH == 0 {
|
||||
None
|
||||
} else {
|
||||
Some(&self.inner[LENGTH - 1])
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
Compiler
|
||||
--------
|
||||
|
||||
- [Added the `-Csplit-debuginfo` codegen option for macOS platforms.][79570]
|
||||
This option controls whether debug information is split across multiple files
|
||||
or packed into a single file. **Note** This option is unstable on other platforms.
|
||||
- [Added tier 3\* support for `aarch64_be-unknown-linux-gnu`,
|
||||
`aarch64-unknown-linux-gnu_ilp32`, and `aarch64_be-unknown-linux-gnu_ilp32` targets.][81455]
|
||||
- [Added tier 3 support for `i386-unknown-linux-gnu` and `i486-unknown-linux-gnu` targets.][80662]
|
||||
- [The `target-cpu=native` option will now detect individual features of CPUs.][80749]
|
||||
- [Rust now uses `inline-asm` for stack probes when used with LLVM 11.0.1+][77885]
|
||||
|
||||
\* Refer to Rust's [platform support page][forge-platform-support] for more
|
||||
information on Rust's tiered platform support.
|
||||
|
||||
Libraries
|
||||
---------
|
||||
|
||||
- [`Box::downcast` is now also implemented for any `dyn Any + Send + Sync` object.][80945]
|
||||
- [`str` now implements `AsMut<str>`.][80279]
|
||||
- [`u64` and `u128` now implement `From<char>`.][79502]
|
||||
- [`Error` is now implemented for `&T` where `T` implements `Error`.][75180]
|
||||
- [`Poll::{map_ok, map_err}` are now implemented for `Poll<Option<Result<T, E>>>`.][80968]
|
||||
- [`unsigned_abs` is now implemented for all signed integer types.][80959]
|
||||
- [`io::Empty` now implements `io::Seek`.][78044]
|
||||
- [`rc::Weak<T>` and `sync::Weak<T>`'s methods such as `as_ptr` are now implemented for
|
||||
`T: ?Sized` types.][80764]
|
||||
|
||||
Stabilized APIs
|
||||

||||

|
||||
Cargo
|
||||
-----
|
||||
- [Added the `split-debuginfo` profile option to control the -Csplit-debuginfo
|
||||
codegen option.][cargo/9112]
|
||||
- [Added the `resolver` field to `Cargo.toml` to enable the new feature resolver
|
||||
and CLI option behavior.][cargo/8997] Version 2 of the feature resolver will try
|
||||
to avoid unifying features of dependencies where that unification could be unwanted.
|
||||
Such as using the same dependency with a `std` feature in a build scripts and
|
||||
proc-macros, while using the `no-std` feature in the final binary. See the
|
||||
[Cargo book documentation][feature-resolver@2.0] for more information on the feature.
|
||||
|
||||
Rustdoc
|
||||
-------
|
||||
|
||||
- [Rustdoc will now include documentation for methods available from `Deref` traits.][80653]
|
||||
- [You can now provide a `--default-theme` flag which sets the default theme to use for
|
||||
documentation.][79642]
|
||||
|
||||
Various improvements to intra-doc links:
|
||||
|
||||
- [You can link to non-path primitives such as `slice`.][80181]
|
||||
- [You can link to associated items.][74489]
|
||||
- [You can now include generic parameters when linking to items, like `Vec<T>`.][76934]
|
||||
|
||||
Misc
|
||||
----
|
||||
- [You can now pass `--include-ignored` to tests (e.g. with
|
||||
`cargo test -- --include-ignored`) to include testing tests marked `#[ignore]`.][80053]
|
||||
|
||||
Compatibility Notes
|
||||
-------------------
|
||||
|
||||
- [WASI platforms no longer use the `wasm-bindgen` ABI, and instead use the wasm32 ABI.][79998]
|
||||
- [`rustc` no longer promotes division, modulo and indexing operations to `const` that
|
||||
could fail.][80579]
|
||||
- [The minimum version of glibc for the following platforms has been bumped to version 2.31
|
||||
for the distributed artifacts.][81521]
|
||||
- `armv5te-unknown-linux-gnueabi`
|
||||
- `sparc64-unknown-linux-gnu`
|
||||
- `thumbv7neon-unknown-linux-gnueabihf`
|
||||
- `armv7-unknown-linux-gnueabi`
|
||||
- `x86_64-unknown-linux-gnux32`
|
||||
|
||||
Internal Only
|
||||
-------------
|
||||
|
||||
- [Consistently avoid constructing optimized MIR when not doing codegen][80718]
