Highlights
|
||||
----------
|
||||
|
||||
* The [`std::fs` module has been expanded][fs-expand] to expand the set of
|
||||
functionality exposed:

|
|||
* A `symlink_metadata` function has been added.
|
||||
* The `fs::Metadata` structure now lowers to its OS counterpart, providing
|
||||
access to all underlying information.
|
||||
* The compiler contains extended explanations of many errors. When it
|
||||
emits such an error it also suggests using the `--explain` flag to
|
||||
read the extended explanations, which are also [cataloged on the web
|
||||
site][err].
|
||||
* Thanks to multiple [improvements][sk] to [type checking][pre], as
|
||||
well as other work, the time to bootstrap the compiler decreased by
|
||||
32%.

Libraries
|
||||
---------
|
||||
|
||||
* The `str::split_whitespace` method splits a string on unicode
|
||||
whitespace boundaries.
|
||||
* On both Windows and Unix, new extension traits provide conversion of
|
||||
I/O types to and from the underlying system handles. On Unix, these
|
||||
traits are [`FrowRawFd`] and [`AsRawFd`], on Windows `FromRawHandle`
|
||||
and `AsRawHandle`. These are implemented for `File`, `TcpStream`,
|
||||
`TcpListener`, and `UpdSocket`. Further implementations for
|
||||
`std::process` will be stabilized later.
|
||||
* On Unix, [`std::os::unix::symlink`] creates symlinks. On
|
||||
Windows, symlinks can be created with
|
||||
`std::os::windows::symlink_dir` and
|
||||
`std::os::windows::symlink_file`.
|
||||
* The `mpsc::Receiver` type can now be converted into an iterator with
|
||||
`into_iter` on the [`IntoIterator`] trait.
|
||||
* `Ipv4Addr` can be created from `u32` with the `From<u32>`
|
||||
implementation of the [`From`] trait.
|
||||
* The `Debug` implementation for `RangeFull` [creates output that is
|
||||
more consistent with other implementations][rf].
|
||||
* [`Debug` is implemented for `File`][file].
|
||||
* The `Default` implementation for `Arc` [no longer requires `Sync +
|
||||
Send`][arc].
|
||||
* [The `Iterator` methods `count`, `nth`, and `last` have been
|
||||
overridden for slices to have O(1) performance instead of O(n)][si].
|
||||
* Incorrect handling of paths on Windows has been improved in both the
|
||||
compiler and the standard library.
|
||||
* [`AtomicPtr` gained a `Default` implementation][ap].
|
||||
* In accordance with Rust's policy on arithmetic overflow `abs` now
|
||||
[panics on overflow when debug assertions are enabled][abs].
|
||||
* The [`Cloned`] iterator, which was accidentally left unstable for
|
||||
1.0 [has been stabilized][c].
|
||||
* The [`Incoming`] iterator, which iterates over incoming TCP
|
||||
connections, and which was accidentally unnamable in 1.0, [is now
|
||||
properly exported][inc].
|
||||
* [`BinaryHeap`] no longer corrupts itself [when functions called by
|
||||
`sift_up` or `sift_down` panic][bh].
|
||||
* The [`split_off`] method of `LinkedList` [no longer corrupts
|
||||
the list in certain scenarios][ll].
|
||||
|
||||
Misc
|
||||
----
|
||||
|
||||
* Type checking performance [has improved notably][sk] with
|
||||
[multiple improvements][pre].
|
||||
* The compiler [suggests code changes][ch] for more errors.
|
||||
* rustc and it's build system have experimental support for [building
|
||||
toolchains against MUSL][m] instead of glibc on Linux.
|
||||
* The compiler defines the `target_env` cfg value, which is used for
|
||||
distinguishing toolchains that are otherwise for the same
|
||||
platform. Presently this is set to `gnu` for common GNU Linux
|
||||
targets and for MinGW targets, and `musl` for MUSL Linux targets.
|
||||
* The [`cargo rustc`][crc] command invokes a build with custom flags
|
||||
to rustc.
|
||||
* [Android executables are always position independent][pie].
|
||||
* [The `drop_with_repr_extern` lint warns about mixing `repr(C)`
|
||||
with `Drop`][drop].
