An automated script was run against the `.rs` and `.md` files, subsituting every occurrence of `task` with `thread`. In the `.rs` files, only the texts in the comment blocks were affected.

Sweeten the two main HashMap/HashSet examples from [here](http://doc.rust-lang.org/std/collections/struct.HashMap.html) and [here](http://doc.rust-lang.org/std/collections/struct.HashSet.html) with some deref and loop sugar.

2015-05-03Clean up HashMap examplesPascal Hertleif-8/+8
2015-05-03Restore HashMap performance by allowing some functions to be inlinedBjörn Steinbrink-0/+1
Since the hashmap and its hasher are implemented in different crates, we currently can't benefit from inlining, which means that especially for small, fixed size keys, there is a huge overhead in hash calculations, because the compiler can't apply optimizations that only apply for these keys. Fixes the brainfuck benchmark in #24014.
2015-05-01std: Remove index notation on slice iteratorsAlex Crichton-2/+1
These implementations were intended to be unstable, but currently the stability attributes cannot handle a stable trait with an unstable `impl` block. This commit also audits the rest of the standard library for explicitly-`#[unstable]` impl blocks. No others were removed but some annotations were changed to `#[stable]` as they're defacto stable anyway. One particularly interesting `impl` marked `#[stable]` as part of this commit is the `Add<&[T]>` impl for `Vec<T>`, which uses `push_all` and implicitly clones all elements of the vector provided. Closes #24791

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.

The collections debug helpers no longer prefix output with the collection name, in line with the current conventions for Debug implementations.

2015-03-20Future-proof indexing on maps: remove IndexMutAaron Turon-13/+1
This commit removes the `IndexMut` impls on `HashMap` and `BTreeMap`, in order to future-proof the API against the eventual inclusion of an `IndexSet` trait. Ideally, we would eventually be able to support: ```rust map[owned_key] = val; map[borrowed_key].mutating_method(arguments); &mut map[borrowed_key]; ``` but to keep the design space as unconstrained as possible, we do not currently want to support `IndexMut`, in case some other strategy will eventually be needed. Code currently using mutating index notation can use `get_mut` instead. [breaking-change] Closes #23448

2015-03-03Add `core::num::wrapping` and fix overflow errors.James Miller-0/+7
Many of the core rust libraries have places that rely on integer wrapping behaviour. These places have been altered to use the wrapping_* methods: * core::hash::sip - A number of macros * core::str - The `maximal_suffix` method in `TwoWaySearcher` * rustc::util::nodemap - Implementation of FnvHash * rustc_back::sha2 - A number of macros and other places * rand::isaac - Isaac64Rng, changed to use the Wrapping helper type Some places had "benign" underflow. This is when underflow or overflow occurs, but the unspecified value is not used due to other conditions. * collections::bit::Bitv - underflow when `self.nbits` is zero. * collections::hash::{map,table} - Underflow when searching an empty table. Did cause undefined behaviour in this case due to an out-of-bounds ptr::offset based on the underflowed index. However the resulting pointers would never be read from. * syntax::ext::deriving::encodable - Underflow when calculating the index of the last field in a variant with no fields. These cases were altered to avoid the underflow, often by moving the underflowing operation to a place where underflow could not happen. There was one case that relied on the fact that unsigned arithmetic and two's complement arithmetic are identical with wrapping semantics. This was changed to use the wrapping_* methods. Finally, the calculation of variant discriminants could overflow if the preceeding discriminant was `U64_MAX`. The logic in `rustc::middle::ty` for this was altered to avoid the overflow completely, while the remaining places were changed to use wrapping methods. This is because `rustc::middle::ty::enum_variants` now throws an error when the calculated discriminant value overflows a `u64`. This behaviour can be triggered by the following code: ``` enum Foo { A = U64_MAX, B } ``` This commit also implements the remaining integer operators for Wrapped<T>.
