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

2015-08-12Remove all unstable deprecated functionalityAlex Crichton-26/+0
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`. [breaking-change]
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.

2015-03-31std: Stabilize last bits of io::ErrorAlex Crichton-2/+44
This commit stabilizes a few remaining bits of the `io::Error` type: * The `Error::new` method is now stable. The last `detail` parameter was removed and the second `desc` parameter was generalized to `E: Into<Box<Error>>` to allow creating an I/O error from any form of error. Currently there is no form of downcasting, but this will be added in time. * An implementation of `From<&str> for Box<Error>` was added to liballoc to allow construction of errors from raw strings. * The `Error::raw_os_error` method was stabilized as-is. * Trait impls for `Clone`, `Eq`, and `PartialEq` were removed from `Error` as it is not possible to use them with trait objects. This is a breaking change due to the modification of the `new` method as well as the removal of the trait implementations for the `Error` type. [breaking-change]

2015-03-30convert: remove FromError, use From<E> insteadSean McArthur-3/+3
This removes the FromError trait, since it can now be expressed using the new convert::Into trait. All implementations of FromError<E> where changed to From<E>, and `try!` was changed to use From::from instead. Because this removes FromError, it is a breaking change, but fixing it simply requires changing the words `FromError` to `From`, and `from_error` to `from`. [breaking-change]
2015-03-30std: Stabilize the rest of Any/BoxAnyAlex Crichton-20/+6
This commit stabilizes the following APIs: * `TypeId::of` - now that it has an `Any` bound it's ready to be stable. * `Box<Any>::downcast` - now that an inherent impl on `Box<Any>` as well as `Box<Any+Send>` is allowed the `BoxAny` trait is removed in favor of these inherent methods. This is a breaking change due to the removal of the `BoxAny` trait, but consumers can simply remove imports to fix crates. [breaking-change]
