| 1 | +Version 1.36.0 (2019-07-04) |
| 2 | +========================== |
| 3 | + |
| 4 | +Language |
| 5 | +-------- |
| 6 | +- [Non-Lexical Lifetimes are now enabled on the 2015 edition.][59114] |
| 7 | +- [The order of traits in trait objects no longer affects the semantics of that |
| 8 | + object.][59445] e.g. `dyn Send + fmt::Debug` is now equivalent to |
| 9 | + `dyn fmt::Debug + Send`, where this was previously not the case. |
| 10 | + |
| 11 | +Libraries |
| 12 | +--------- |
| 13 | +- [`HashMap`'s implementation has been replaced with `hashbrown::HashMap` implementation.][58623] |
| 14 | +- [`TryFromSliceError` now implements `From<Infallible>`.][60318] |
| 15 | +- [`mem::needs_drop` is now available as a const fn.][60364] |
| 16 | +- [`alloc::Layout::from_size_align_unchecked` is now available as a const fn.][60370] |
| 17 | +- [`String` now implements `BorrowMut<str>`.][60404] |
| 18 | +- [`io::Cursor` now implements `Default`.][60234] |
| 19 | +- [Both `NonNull::{dangling, cast}` are now const fns.][60244] |
| 20 | +- [The `alloc` crate is now stable.][59675] `alloc` allows you to use a subset |
| 21 | + of `std` (e.g. `Vec`, `Box`, `Arc`) in `#![no_std]` environments if the |
| 22 | + environment has access to heap memory allocation. |
| 23 | +- [`String` now implements `From<&String>`.][59825] |
| 24 | +- [You can now pass multiple arguments to the `dbg!` macro.][59826] `dbg!` will |
| 25 | + return a tuple of each argument when there is multiple arguments. |
| 26 | +- [`Result::{is_err, is_ok}` are now `#[must_use]` and will produce a warning if |
| 27 | + not used.][59648] |
| 28 | + |
| 29 | +Stabilized APIs |
| 30 | +--------------- |
| 31 | +- [`VecDeque::rotate_left`] |
| 32 | +- [`VecDeque::rotate_right`] |
| 33 | +- [`Iterator::copied`] |
| 34 | +- [`io::IoSlice`] |
| 35 | +- [`io::IoSliceMut`] |
| 36 | +- [`Read::read_vectored`] |
| 37 | +- [`Write::write_vectored`] |
| 38 | +- [`str::as_mut_ptr`] |
| 39 | +- [`mem::MaybeUninit`] |
| 40 | +- [`pointer::align_offset`] |
| 41 | +- [`future::Future`] |
| 42 | +- [`task::Context`] |
| 43 | +- [`task::RawWaker`] |
| 44 | +- [`task::RawWakerVTable`] |
| 45 | +- [`task::Waker`] |
| 46 | +- [`task::Poll`] |
| 47 | + |
| 48 | +Cargo |
| 49 | +----- |
| 50 | +- [Cargo will now produce an error if you attempt to use the name of a required dependency as a feature.][cargo/6860] |
| 51 | +- [You can now pass the `--offline` flag to run cargo without accessing the network.][cargo/6934] |
| 52 | + |
| 53 | +You can find further change's in [Cargo's 1.36.0 release notes][cargo-1-36-0]. |
| 54 | + |
| 55 | +Clippy |
