Version 1.35.0 (2019-05-23) ========================== 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] Libraries --------- - [`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`] - [`RefCell::map_split`] - [`ptr::hash`] - [`Range::contains`] - [`RangeFrom::contains`] - [`RangeTo::contains`] - [`RangeInclusive::contains`] - [`RangeToInclusive::contains`] - [`Option::copied`] 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. Misc ---- - [The Rust toolchain is now available natively for musl based distros.][58575] [59460]: rust-lang/rust#59460 [59464]: rust-lang/rust#59464 [59500]: rust-lang/rust#59500 [59512]: rust-lang/rust#59512 [59580]: rust-lang/rust#59580 [59283]: rust-lang/rust#59283 [59451]: rust-lang/rust#59451 [59076]: rust-lang/rust#59076 [58778]: rust-lang/rust#58778 [58717]: rust-lang/rust#58717 [58369]: rust-lang/rust#58369 [58423]: rust-lang/rust#58423 [58080]: rust-lang/rust#58080 [57847]: rust-lang/rust#57847 [58575]: rust-lang/rust#58575 [cargo/6298]: rust-lang/cargo#6298 [`f32::copysign`]: https://doc.rust-lang.org/stable/std/primitive.f32.html#method.copysign [`f64::copysign`]: https://doc.rust-lang.org/stable/std/primitive.f64.html#method.copysign [`RefCell::replace_with`]: https://doc.rust-lang.org/stable/std/cell/struct.RefCell.html#method.replace_with [`RefCell::map_split`]: https://doc.rust-lang.org/stable/std/cell/struct.RefCell.html#method.map_split [`ptr::hash`]: https://doc.rust-lang.org/stable/std/ptr/fn.hash.html [`Range::contains`]: https://doc.rust-lang.org/std/ops/struct.Range.html#method.contains [`RangeFrom::contains`]: https://doc.rust-lang.org/std/ops/struct.RangeFrom.html#method.contains [`RangeTo::contains`]: https://doc.rust-lang.org/std/ops/struct.RangeTo.html#method.contains [`RangeInclusive::contains`]: https://doc.rust-lang.org/std/ops/struct.RangeInclusive.html#method.contains [`RangeToInclusive::contains`]: https://doc.rust-lang.org/std/ops/struct.RangeToInclusive.html#method.contains [`Option::copied`]: https://doc.rust-lang.org/std/option/enum.Option.html#method.copied
