2017-01-25std: Stabilize APIs for the 1.16.0 releaseAlex Crichton-3/+1
This commit applies the stabilization/deprecations of the 1.16.0 release, as tracked by the rust-lang/rust issue tracker and the final-comment-period tag. The following APIs were stabilized: * `VecDeque::truncate` * `VecDeque::resize` * `String::insert_str` * `Duration::checked_{add,sub,div,mul}` * `str::replacen` * `SocketAddr::is_ipv{4,6}` * `IpAddr::is_ipv{4,6}` * `str::repeat` * `Vec::dedup_by` * `Vec::dedup_by_key` * `Result::unwrap_or_default` * `<*const T>::wrapping_offset` * `<*mut T>::wrapping_offset` * `CommandExt::creation_flags` (on Windows) * `File::set_permissions` * `String::split_off` The following APIs were deprecated * `EnumSet` - replaced with other ecosystem abstractions, long since unstable Closes #27788 Closes #35553 Closes #35774 Closes #36436 Closes #36949 Closes #37079 Closes #37087 Closes #37516 Closes #37827 Closes #37916 Closes #37966 Closes #38080

2016-11-04Auto merge of #37306 - bluss:trusted-len, r=alexcrichtonbors-1/+10
Add Iterator trait TrustedLen to enable better FromIterator / Extend This trait attempts to improve FromIterator / Extend code by enabling it to trust the iterator to produce an exact number of elements, which means that reallocation needs to happen only once and is moved out of the loop. `TrustedLen` differs from `ExactSizeIterator` in that it attempts to include _more_ iterators by allowing for the case that the iterator's len does not fit in `usize`. Consumers must check for this case (for example they could panic, since they can't allocate a collection of that size). For example, chain can be TrustedLen and all numerical ranges can be TrustedLen. All they need to do is to report an exact size if it fits in `usize`, and `None` as the upper bound otherwise. The trait describes its contract like this: ``` An iterator that reports an accurate length using size_hint. The iterator reports a size hint where it is either exact (lower bound is equal to upper bound), or the upper bound is `None`. The upper bound must only be `None` if the actual iterator length is larger than `usize::MAX`. The iterator must produce exactly the number of elements it reported. This trait must only be implemented when the contract is upheld. Consumers of this trait must inspect `.size_hint()`’s upper bound. ``` Fixes #37232

Add `unwrap_or_default` method to `Result` Fixes #37025
2016-10-31Changed most vec! invocations to use square bracesiirelu-2/+2
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.

2016-01-22Move cold panic functions in Option and ResultUlrik Sverdrup-21/+9
Move functions out of their impl blocks; avoids unnecessary monomorphization by type parameters that are irrelevant to the message output.
2016-01-22Use cold functions for panic formatting Option::expect, Result::unwrap etcUlrik Sverdrup-6/+23
Option::expect, Result::unwrap, unwrap_err, expect These methods are marked inline, but insert a big chunk of formatting code, as well as other error path related code, such as deallocating a std::io::Error if you have one. We can explicitly separate out that code path into a function that is never inline, since the panicking case should always be rare.

2015-11-12Auto merge of #29544 - Ryman:reduce_doc_warnings, r=steveklabnikbors-0/+6
Did this alphabetically, so I didn't see [how `std` was doing things](https://dxr.mozilla.org/rust/source/src/libstd/lib.rs#215) till I was nearly finished. If you prefer to add crate-level-whitelists like std instead of test-level, I can rebase with that strategy. A number of these commits can probably be dropped as the crates don't have much to test, and are deprecated. Let me know which if any to drop!
