2015-10-02std: Add AsRef/AsMut impls to Box/Rc/ArcAlex Crichton-0/+10
These common traits were left off originally by accident from these smart pointers, and a past attempt (#26008) to add them was later reverted (#26160) due to unexpected breakge (#26096) occurring. The specific breakage in worry is the meaning of this return value changed: let a: Box<Option<T>> = ...; a.as_ref() Currently this returns `Option<&T>` but after this change it will return `&Option<T>` because the `AsRef::as_ref` method shares the same name as `Option::as_ref`. A [crater report][crater] of this change, however, has shown that the fallout of this change is quite minimal. These trait implementations are "the right impls to add" to these smart pointers and would enable various generalizations such as those in #27197. [crater]: https://gist.github.com/anonymous/0ba4c3512b07641c0f99 This commit is a breaking change for the above reasons mentioned, and the mitigation strategies look like any of: Option::as_ref(&a) a.as_ref().as_ref() (*a).as_ref()

2015-09-11std: Stabilize/deprecate features for 1.4Alex Crichton-11/+3

This commit removes all unstable and deprecated functions in the standard library. A release was recently cut (1.3) which makes this a good time for some spring cleaning of the deprecated functions.

2015-08-03syntax: Implement #![no_core]Alex Crichton-1/+2
This commit is an implementation of [RFC 1184][rfc] which tweaks the behavior of the `#![no_std]` attribute and adds a new `#![no_core]` attribute. The `#![no_std]` attribute now injects `extern crate core` at the top of the crate as well as the libcore prelude into all modules (in the same manner as the standard library's prelude). The `#![no_core]` attribute disables both std and core injection. [rfc]: https://github.com/rust-lang/rfcs/pull/1184
2015-07-30Auto merge of #27371 - Gankro:str-clone, r=alexcrichtonbors-0/+13
This is a minor [breaking-change], as it changes what `boxed_str.to_owned()` does (previously it would deref to `&str` and call `to_owned` on that to get a `String`). However `Box<str>` is such an exceptionally rare type that this is not expected to be a serious concern. Also a `Box<str>` can be freely converted to a `String` to obtain the previous result anyway.

2015-07-27std: Deprecate a number of unstable featuresAlex Crichton-0/+3
Many of these have long since reached their stage of being obsolete, so this commit starts the removal process for all of them. The unstable features that were deprecated are: * cmp_partial * fs_time * hash_default * int_slice * iter_min_max * iter_reset_fuse * iter_to_vec * map_in_place * move_from * owned_ascii_ext * page_size * read_and_zero * scan_state * slice_chars * slice_position_elem * subslice_offset

2015-06-17std: Move free-functions to associated functionsAlex Crichton-3/+26
This commit moves the free functions in the `rc`, `arc`, and `boxed` modules to associated functions on their respective types, following the recent trend towards this pattern. The previous free functions are all left in-place with `#[deprecated]` pointers towards the new locations. This commit also deprecates `arc::get_mut` and `Arc::make_unique` with no replacement as they are racy in the face of weak pointers.

2015-06-17alloc: Split apart the global `alloc` featureAlex Crichton-3/+3
2015-06-17core: Split apart the global `core` featureAlex Crichton-8/+10
This commit shards the broad `core` feature of the libcore library into finer grained features. This split groups together similar APIs and enables tracking each API separately, giving a better sense of where each feature is within the stabilization process. A few minor APIs were deprecated along the way: * Iterator::reverse_in_place * marker::NoCopy

2015-04-30Add downcasting to std::error::ErrorAaron Turon-3/+8
This commit brings the `Error` trait in line with the [Error interoperation RFC](https://github.com/rust-lang/rfcs/pull/201) by adding downcasting, which has long been intended. This change means that for any `Error` trait objects that are `'static`, you can downcast to concrete error types. To make this work, it is necessary for `Error` to inherit from `Reflect` (which is currently used to mark concrete types as "permitted for reflection, aka downcasting"). This is a breaking change: it means that impls like ```rust impl<T> Error for MyErrorType<T> { ... } ``` must change to something like ```rust impl<T: Reflect> Error for MyErrorType<T> { ... } ``` except that `Reflect` is currently unstable (and should remain so for the time being). For now, code can instead bound by `Any`: ```rust impl<T: Any> Error for MyErrorType<T> { ... } ``` which *is* stable and has `Reflect` as a super trait. The downside is that this imposes a `'static` constraint, but that only constrains *when* `Error` is implemented -- it does not actually constrain the types that can implement `Error`.

2015-04-21rollup merge of #24541: alexcrichton/issue-24538Alex Crichton-1/+0
This is an implementation of [RFC 1030][rfc] which adds these traits to the prelude and additionally removes all inherent `into_iter` methods on collections in favor of the trait implementation (which is now accessible by default). [rfc]: https://github.com/rust-lang/rfcs/pull/1030 This is technically a breaking change due to the prelude additions and removal of inherent methods, but it is expected that essentially no code breaks in practice. [breaking-change] Closes #24538
2015-04-20Clean up Box documentation.Steve Klabnik-8/+13
Without the `box` keyword, one of these two reasons is not correct, so let's just eliminate this section and elaborate on the reason for the legit use case inline. Fixes #24511

Conflicts: src/liballoc/boxed.rs
2015-04-01Collect the definition of the `Error` trait into `libstd` for now. ThisNiko Matsakis-51/+2
sidesteps a coherence difficulty where `liballoc` had to prove that `&str: !Error`, which didn't involve any local types.
2015-04-01Remove `Thunk` struct and `Invoke` trait; change `Thunk` to be an aliasNiko Matsakis-8/+4
for `Box<FnBox()>`. I found the alias was still handy because it is shorter than the fully written type. This is a [breaking-change]: convert code using `Invoke` to use `FnBox`, which is usually pretty straight-forward. Code using thunk mostly works if you change `Thunk::new => Box::new` and `foo.invoke(arg)` to `foo(arg)`.
2015-04-01Add (unstable) FnBox trait as a nicer replacement for `Thunk`. The docNiko Matsakis-0/+75
comment includes a test that also shows how it can be used.
