|
||||
==========================
|
||||
|
||||
Language
|
||||
--------
|
||||
- [`FnOnce`, `FnMut`, and the `Fn` traits are now implemented for `Box<FnOnce>`,
|
||||
`Box<FnMut>`, and `Box<Fn>` respectively.][59500]
|
||||
- [You can now coerce closures into unsafe function pointers.][59580] e.g.
|
||||
```rust
|
||||
unsafe fn call_unsafe(func: unsafe fn()) {
|
||||
func()
|
||||
}
|
||||
|
||||
pub fn main() {
|
||||
unsafe { call_unsafe(|| {}); }
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
Compiler
|
||||
--------
|
||||
- [Added the `armv6-unknown-freebsd-gnueabihf` and
|
||||
`armv7-unknown-freebsd-gnueabihf` targets.][58080]
|
||||
- [Added the `wasm32-unknown-wasi` target.][59464]
|
||||
|
||||
|
||||

|
||||
---------
|
||||
- [`Thread` will now show its ID in `Debug` output.][59460]
|
||||
- [`StdinLock`, `StdoutLock`, and `StderrLock` now implement `AsRawFd`.][59512]
|
||||
- [`alloc::System` now implements `Default`.][59451]
|
||||
- [Expanded `Debug` output (`{:#?}`) for structs now has a trailing comma on the
|
||||
last field.][59076]
|
||||
- [`char::{ToLowercase, ToUppercase}` now
|
||||
implement `ExactSizeIterator`.][58778]
|
||||
- [All `NonZero` numeric types now implement `FromStr`.][58717]
|
||||
- [Removed the `Read` trait bounds
|
||||
on the `BufReader::{get_ref, get_mut, into_inner}` methods.][58423]
|
||||
- [You can now call the `dbg!` macro without any parameters to print the file
|
||||
and line where it is called.][57847]
|
||||
- [In place ASCII case conversions are now up to 4× faster.][59283]
|
||||
e.g. `str::make_ascii_lowercase`
|
||||
- [`hash_map::{OccupiedEntry, VacantEntry}` now implement `Sync`
|
||||
and `Send`.][58369]
|
||||
|
||||
Stabilized APIs

||||
---------------
|
||||
- [`f32::copysign`]
|
||||
- [`f64::copysign`]
|
||||
- [`RefCell::replace_with`]

Cargo
|
||||
-----
|
||||
- [You can now set `cargo:rustc-cdylib-link-arg` at build time to pass custom
|
||||
linker arguments when building a `cdylib`.][cargo/6298] Its usage is highly
|
||||
platform specific.
|
||||
|
||||

|
||||
- [The Rust toolchain is now available natively for musl based distros.][58575]
