Replaced by `string::raw::from_buf_len`
[breaking-change]
|
|
Use `string::raw::from_buf` instead
[breaking-change]
|
|
This trait was only implemented by `String`. It provided the methods
`into_bytes` and `append`, both of which **are already implemented as normal
methods** of `String` (not as trait methods). This change improves the
consistency of strings.
This shouldn't break any code, except if somebody has implemented
`OwnedStr` for a user-defined type.
|
|
Link to mentioned methods. Use `# Failure` tags to describe failure.
Make `pop_equiv`, `find_equiv` and `get_copy` standalone.
|
|
|
|
|
|
|
|
Add an example showing how to use the map with a custom type. Fill in
examples for methods in the hashmap file without ones.
Also move pop_equiv next to related public methods, to not create a
duplicate trait implementation in the docs.
|
|
|
|
|
|
Implement for Vec, DList, RingBuf. Add MutableSeq to the prelude.
Since the collections traits are in the prelude most consumers of
these methods will continue to work without change.

Adds a new runtime unwinding function that encapsulates the printing of the words "explicit failure" when `fail!()` is called w/o arguments.

This is the lowest-hanging fruit in the fail-bloat wars. Further fixes are going to require harder tradeoffs.

Adds a special-case fail function, rustrt::unwind::begin_unwind_no_time_to_explain,

Summary:
* alloc::rc module stable
* Rc type stable
* Functions relating to weak references experimental
* core::cmp module stable
* PartialEq/Eq/PartialOrd/Ord unstable because trait reform will make them change again
* Equiv experimental because there may be better sol'ns
* lexical_ordering deprecated because it can be done trivially with the Ord trait
* min/max stable
* std::task module stable
* TaskBuilder::stdout/stderr experimental because we aren't certain we want to configure the environment this way
* try_future experimental because Future is experimental
* try unstable because the error type might change
* deschedule/failing unstable
The major thing I did differently than previously-discussed is that I made `try` experimental: there's been discussion that the error type `Box<Any + Send>` is not sufficient.
Per https://github.com/rust-lang/meeting-minutes/blob/master/Meeting-API-review-2014-07-16.md.

This is now linked to in the guide, so I want to make sure it's good. This
adds a bit more explanation, and brings usage in line with current good style.

Most stable. deschedule/failing experimental because of concerns about
naming and desirability.
Adds task::name() to replace deprecated task::with_name().

Example how to use the set with a custom type. Fill in examples for the missing methods.

Add main example and simple examples for the methods.

- `width()` computes the displayed width of a string, ignoring the width of control characters.
- arguably we might do *something* else for control characters, but the question is, what?
- users who want to do something else can iterate over chars()
- `graphemes()` returns a `Graphemes` struct, which implements an iterator over the grapheme clusters of a &str.
- fully compliant with [UAX#29](http://www.unicode.org/reports/tr29/#Grapheme_Cluster_Boundaries)
- passes all [Unicode-supplied tests](http://www.unicode.org/reports/tr41/tr41-15.html#Tests29)
- added code to generate additionial categories in `unicode.py`
- `Cn` aka `Not_Assigned`
- categories necessary for grapheme cluster breaking
- tidied up the exports from libunicode
- all exports are exposed through a module rather than directly at crate root.
- std::prelude imports UnicodeChar and UnicodeStrSlice from std::char and std::str rather than directly from libunicode

- Graphemes and GraphemeIndices structs implement iterators over
grapheme clusters analogous to the Chars and CharOffsets for chars in
a string. Iterator and DoubleEndedIterator are available for both.
- tidied up the exports for libunicode. crate root exports are now moved
into more appropriate module locations:
- UnicodeStrSlice, Words, Graphemes, GraphemeIndices are in str module
- UnicodeChar exported from char instead of crate root
- canonical_combining_class is exported from str rather than crate root
Since libunicode's exports have changed, programs that previously relied
on the old export locations will need to change their `use` statements
to reflect the new ones. See above for more information on where the new
exports live.

Currently when a read-only file has unlink() invoked on it on windows, the call
will fail. On unix, however, the call will succeed. In order to have a more
consistent behavior across platforms, this error is recognized on windows and
the file is changed to read-write before removal is attempted.

This patch adds doc examples for the make_absolute, change_dir,
errors_string and args functions in the os module.

This PR is the outcome of the library stabilization meeting for the
`liballoc::owned` and `libcore::cell` modules.
Aside from the stability attributes, there are a few breaking changes:
* The `owned` modules is now named `boxed`, to better represent its
contents. (`box` was unavailable, since it's a keyword.) This will
help avoid the misconception that `Box` plays a special role wrt
ownership.
* The `AnyOwnExt` extension trait is renamed to `BoxAny`, and its `move`
method is renamed to `downcast`, in both cases to improve clarity.
* The recently-added `AnySendOwnExt` extension trait is removed; it was
not being used and is unnecessary.

The `hash` module was not included in an earlier pass that sets baseline
stability of modules within `std` to `experimental`.
