sync: Move underneath libstd This commit is the final step in the libstd facade, #13851. The purpose of this commit is to move libsync underneath the standard library, behind the facade. This will allow core primitives like channels, queues, and atomics to all live in the same location. There were a few notable changes and a few breaking changes as part of this movement: * The `Vec` and `String` types are reexported at the top level of libcollections * The `unreachable!()` macro was copied to libcore * The `std::rt::thread` module was moved to librustrt, but it is still reexported at the same location. * The `std::comm` module was moved to libsync * The `sync::comm` module was moved under `sync::comm`, and renamed to `duplex`. It is now a private module with types/functions being reexported under `sync::comm`. This is a breaking change for any existing users of duplex streams. * All concurrent queues/deques were moved directly under libsync. They are also all marked with #![experimental] for now if they are public. * The `task_pool` and `future` modules no longer live in libsync, but rather live under `std::sync`. They will forever live at this location, but they may move to libsync if the `std::task` module moves as well. [breaking-change] 2014-06-07 18:13:26 +00:00			`use std::sync::Arc;`

Changed most vec! invocations to use square braces Most of the Rust community agrees that the vec! macro is clearer when called using square brackets [] instead of regular brackets (). Most of these ocurrences are from before macros allowed using different types of brackets. There is one left unchanged in a pretty-print test, as the pretty printer still wants it to have regular brackets. 2016-10-29 21:54:04 +00:00			`let v = vec![1, 2, 3, 4, 5, 6, 7, 8, 9, 10];`

Remove a large amount of deprecated functionality Spring cleaning is here! In the Fall! This commit removes quite a large amount of deprecated functionality from the standard libraries. I tried to ensure that only old deprecated functionality was removed. This is removing lots and lots of deprecated features, so this is a breaking change. Please consult the deprecation messages of the deleted code to see how to migrate code forward if it still needs migration.

std: Tweak String implementations This commit performs a pass over the implementations of the new `String` trait in the formatting module. Some implementations were removed as a conservative move pending an upcoming convention about `String` implementations, and some were added in order to retain consistency across the libraries. Specifically: * All "smart pointers" implement `String` now, adding missing implementations for `Arc` and `Rc`. * The `Vec<T>` and `[T]` types no longer implement `String`. * The `const T` and `mut T` type no longer implement `String`. * The `()` type no longer implements `String`. * The `Path` type's `Show` implementation does not surround itself with `Path {}` (a minor tweak). All implementations of `String` in this PR were also marked `#[stable]` to indicate that the types will continue to implement the `String` trait regardless of what it looks like. 2015-01-07 22:58:31 +00:00			`println!("{:?}", *arc_v);`
