Version 1.6.0 (2016-01-21)
|
||||
==========================
|
||||
|
||||
Language
|
||||
--------
|
||||
|
||||
* The `#![no_std]` attribute causes a crate to not be linked to the
|
||||
standard library, but only the [core library][1.6co], as described
|
||||
in [RFC 1184]. The core library defines common types and traits but
|
||||
has no platform dependencies whatsoever, and is the basis for Rust
|
||||
software in environments that cannot support a full port of the
|
||||
standard library, such as operating systems. Most of the core
|
||||
library is now stable.
|
||||
|
||||
Libraries
|
||||
---------
|
||||
|
||||
* Stabilized APIs:
|
||||
[`Read::read_exact`], [`ErrorKind::UnexpectedEof`] (renamed from
|
||||
`UnexpectedEOF`), [`fs::DirBuilder`], [`fs::DirBuilder::new`],
|
||||
[`fs::DirBuilder::recursive`], [`fs::DirBuilder::create`],
|
||||
[`os::unix::fs::DirBuilderExt`],
|
||||
[`os::unix::fs::DirBuilderExt::mode`], [`vec::Drain`],
|
||||
[`vec::Vec::drain`], [`string::Drain`], [`string::String::drain`],
|
||||
[`vec_deque::Drain`], [`vec_deque::VecDeque::drain`],
|
||||
[`collections::hash_map::Drain`],
|
||||
[`collections::hash_map::HashMap::drain`],
|
||||
[`collections::hash_set::Drain`],
|
||||
[`collections::hash_set::HashSet::drain`],
|
||||
[`collections::binary_heap::Drain`],
|
||||
[`collections::binary_heap::BinaryHeap::drain`],
|
||||
[`Vec::extend_from_slice`] (renamed from `push_all`),
|
||||
[`Mutex::get_mut`], [`Mutex::into_inner`], [`RwLock::get_mut`],
|
||||
[`RwLock::into_inner`], [`Iterator::min_by_key`] (renamed from
|
||||
`min_by`), [`Iterator::max_by_key`] (renamed from `max_by`).
|
||||
* The [core library][1.6co] is stable, as are most of its APIs.
|
||||
* [The `assert_eq!` macro supports arguments that don't implement
|
||||
`Sized`][1.6ae], such as arrays. In this way it behaves more like
|
||||
`assert!`.
|
||||
* Several timer functions that take duration in milliseconds [are
|
||||
deprecated in favor of those that take `Duration`][1.6ms]. These
|
||||
include `Condvar::wait_timeout_ms`, `thread::sleep_ms`, and
|
||||
`thread::park_timeout_ms`.
|
||||
* The algorithm by which `Vec` reserves additional elements was
|
||||
[tweaked to not allocate excessive space][1.6a] while still growing
|
||||
exponentially.
|
||||
* `From` conversions are [implemented from integers to floats][1.6f]
|
||||
in cases where the conversion is lossless. Thus they are not
|
||||
implemented for 32-bit ints to `f32`, nor for 64-bit ints to `f32`
|
||||
or `f64`. They are also not implemented for `isize` and `usize`
|
||||
because the implementations would be platform-specific. `From` is
|
||||
also implemented from `f32` to `f64`.
|
||||
* `From<&Path>` and `From<PathBuf>` are implemented for `Cow<Path>`.
|
||||
* `From<T>` is implemented for `Box<T>`, `Rc<T>` and `Arc<T>`.
|
||||
* `IntoIterator` is implemented for `&PathBuf` and `&Path`.
|
||||
* [`BinaryHeap` was refactored][1.6bh] for modest performance
|
||||
improvements.
|
||||
* Sorting slices that are already sorted [is 50% faster in some
|
||||
cases][1.6s].
|
||||
|
||||
Cargo
|
||||
-----
|
||||
|
||||
* Cargo will look in `$CARGO_HOME/bin` for subcommands [by default][1.6c].
|
||||
* Cargo build scripts can specify their dependencies by emitting the
|
||||
[`rerun-if-changed`][1.6rr] key.
|
||||
* crates.io will reject publication of crates with dependencies that
|
||||
have a wildcard version constraint. Crates with wildcard
|
||||
dependencies were seen to cause a variety of problems, as described
|
||||
in [RFC 1241]. Since 1.5 publication of such crates has emitted a
|
||||
warning.
|
||||
* `cargo clean` [accepts a `--release` flag][1.6cc] to clean the
|
||||
release folder. A variety of artifacts that Cargo failed to clean
|
||||
are now correctly deleted.
|
||||
|
||||
Misc
|
||||
----
|
||||
|
||||
* The `unreachable_code` lint [warns when a function call's argument
|
||||
diverges][1.6dv].
|
||||
* The parser indicates [failures that may be caused by
|
||||
confusingly-similar Unicode characters][1.6uc]
|
||||
* Certain macro errors [are reported at definition time][1.6m], not
|
||||
expansion.
|
||||
|
||||
Compatibility Notes
|
||||
-------------------
|
||||
|
||||
* The compiler no longer makes use of the [`RUST_PATH`][1.6rp]
|
||||
environment variable when locating crates. This was a pre-cargo
|
||||
feature for integrating with the package manager that was
|
||||
accidentally never removed.
|
||||
* [A number of bugs were fixed in the privacy checker][1.6p] that
|
||||
could cause previously-accepted code to break.
|
||||
* [Modules and unit/tuple structs may not share the same name][1.6ts].
|
||||
* [Bugs in pattern matching unit structs were fixed][1.6us]. The tuple
|
||||
struct pattern syntax (`Foo(..)`) can no longer be used to match
|
||||
unit structs. This is a warning now, but will become an error in
|
||||
future releases. Patterns that share the same name as a const are
|
||||
now an error.
|
||||
* A bug was fixed that causes [rustc not to apply default type
|
||||
parameters][1.6xc] when resolving certain method implementations of
|
||||
traits defined in other crates.
