Version 1.9.0 (2016-05-26)
|
||||
==========================
|
||||
|
||||
Language
|
||||
--------
|
||||
|
||||
* The `#[deprecated]` attribute when applied to an API will generate
|
||||
warnings when used. The warnings may be suppressed with
|
||||
`#[allow(deprecated)]`. [RFC 1270].
|
||||
* [`fn` item types are zero sized, and each `fn` names a unique
|
||||
type][1.9fn]. This will break code that transmutes `fn`s, so calling
|
||||
`transmute` on a `fn` type will generate a warning for a few cycles,
|
||||
then will be converted to an error.
|
||||
* [Field and method resolution understand visibility, so private
|
||||
fields and methods cannot prevent the proper use of public fields
|
||||
and methods][1.9fv].
|
||||
* [The parser considers unicode codepoints in the
|
||||
`PATTERN_WHITE_SPACE` category to be whitespace][1.9ws].
|
||||

||||

Libraries
|
||||
---------
|
||||
|
||||
* [`std::sync::Once` is poisoned if its initialization function
|
||||
fails][1.9o].
|
||||
* [`cell::Ref` and `cell::RefMut` can contain unsized types][1.9cu].
|
||||
* [Most types implement `fmt::Debug`][1.9db].
|
||||
* [The default buffer size used by `BufReader` and `BufWriter` was
|
||||
reduced to 8K, from 64K][1.9bf]. This is in line with the buffer size
|
||||
used by other languages.
|
||||
* [`Instant`, `SystemTime` and `Duration` implement `+=` and `-=`.
|
||||
`Duration` additionally implements `*=` and `/=`][1.9ta].
|
||||
* [`Skip` is a `DoubleEndedIterator`][1.9sk].
|
||||
* [`From<[u8; 4]>` is implemented for `Ipv4Addr`][1.9fi].
|
||||
* [`Chain` implements `BufRead`][1.9ch].
|
||||
* [`HashMap`, `HashSet` and iterators are covariant][1.9hc].
|
||||
|
||||
Cargo
|
||||
-----
|
||||
|
||||
* [Cargo can now run concurrently][1.9cc].
|
||||
* [Top-level overrides allow specific revisions of crates to be
|
||||
overridden through the entire crate graph][1.9ct]. This is intended
|
||||
to make upgrades easier for large projects, by allowing crates to be
|
||||
forked temporarily until they've been upgraded and republished.
|
||||
* [Cargo exports a `CARGO_PKG_AUTHORS` environment variable][1.9cp].
|
||||
* [Cargo will pass the contents of the `RUSTFLAGS` variable to `rustc`
|
||||
on the commandline][1.9cf]. `rustc` arguments can also be specified
|
||||
in the `build.rustflags` configuration key.
|
||||
|
||||
Performance
|
||||
-----------
|
||||
|
||||
* [During type unification, the complexity of comparing variables for
|
||||
equivalance was reduced from `O(n!)` to `O(n)`][1.9tu]. This leads
|
||||
to major compile-time improvements in some scenarios.
|
||||
* [`ToString` is specialized for `str`, giving it the same performance
|
||||
as `to_owned`][1.9ts].
|
||||
* [Spawning processes with `Command::output` no longer creates extra
|
||||
threads][1.9sp].
|
||||
* [`#[derive(PartialEq)]` and `#[derive(PartialOrd)]` emit less code
|
||||
for C-like enums][1.9cl].
|
||||
|
||||
Misc
|
||||
----
|
||||
|
||||
* [Passing the `--quiet` flag to a test runner will produce
|
||||
much-abbreviated output][1.9q].
|
||||
* The Rust Project now publishes std binaries for the
|
||||
`mips-unknown-linux-musl`, `mipsel-unknown-linux-musl`, and
|
||||
`i586-pc-windows-msvc` targets.
|
||||
|
||||
Compatibility Notes
|
||||
-------------------
|
||||
|
||||
* [`std::sync::Once` is poisoned if its initialization function
|
||||
fails][1.9o].
|
||||
* [It is illegal to define methods with the same name in overlapping
|
||||
inherent `impl` blocks][1.9sn].
|
||||
* [`fn` item types are zero sized, and each `fn` names a unique
|
||||
type][1.9fn]. This will break code that transmutes `fn`s, so calling
|
||||
`transmute` on a `fn` type will generate a warning for a few cycles,
|
||||
then will be converted to an error.
|
||||
* [Improvements to const evaluation may trigger new errors when integer
|
||||
literals are out of range][1.9ce].
