2015-01-17std: Move the bitflags! macro to a gated crateAlex Crichton-475/+0
In accordance with [collections reform part 2][rfc] this macro has been moved to an external [bitflags crate][crate] which is [available though crates.io][cratesio]. Inside the standard distribution the macro has been moved to a crate called `rustc_bitflags` for current users to continue using. [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0509-collections-reform-part-2.md [crate]: https://github.com/rust-lang/bitflags [cratesio]: http://crates.io/crates/bitflags The major user of `bitflags!` in terms of a public-facing possibly-stable API today is the `FilePermissions` structure inside of `std::io`. This user, however, will likely no longer use `bitflags!` after I/O reform has landed. To prevent breaking APIs today, this structure remains as-is. Current users of the `bitflags!` macro should add this to their `Cargo.toml`: bitflags = "0.1" and this to their crate root: #[macro_use] extern crate bitflags; Due to the removal of a public macro, this is a: [breaking-change]
2015-01-08Improvements to feature stagingBrian Anderson-1/+1
This gets rid of the 'experimental' level, removes the non-staged_api case (i.e. stability levels for out-of-tree crates), and lets the staged_api attributes use 'unstable' and 'deprecated' lints. This makes the transition period to the full feature staging design a bit nicer.
2015-01-07std: Stabilize the std::hash moduleAlex Crichton-3/+3
This commit aims to prepare the `std::hash` module for alpha by formalizing its current interface whileholding off on adding `#[stable]` to the new APIs. The current usage with the `HashMap` and `HashSet` types is also reconciled by separating out composable parts of the design. The primary goal of this slight redesign is to separate the concepts of a hasher's state from a hashing algorithm itself. The primary change of this commit is to separate the `Hasher` trait into a `Hasher` and a `HashState` trait. Conceptually the old `Hasher` trait was actually just a factory for various states, but hashing had very little control over how these states were used. Additionally the old `Hasher` trait was actually fairly unrelated to hashing. This commit redesigns the existing `Hasher` trait to match what the notion of a `Hasher` normally implies with the following definition: trait Hasher { type Output; fn reset(&mut self); fn finish(&self) -> Output; } This `Hasher` trait emphasizes that hashing algorithms may produce outputs other than a `u64`, so the output type is made generic. Other than that, however, very little is assumed about a particular hasher. It is left up to implementors to provide specific methods or trait implementations to feed data into a hasher. The corresponding `Hash` trait becomes: trait Hash<H: Hasher> { fn hash(&self, &mut H); } The old default of `SipState` was removed from this trait as it's not something that we're willing to stabilize until the end of time, but the type parameter is always required to implement `Hasher`. Note that the type parameter `H` remains on the trait to enable multidispatch for specialization of hashing for particular hashers. Note that `Writer` is not mentioned in either of `Hash` or `Hasher`, it is simply used as part `derive` and the implementations for all primitive types. With these definitions, the old `Hasher` trait is realized as a new `HashState` trait in the `collections::hash_state` module as an unstable addition for now. The current definition looks like: trait HashState { type Hasher: Hasher; fn hasher(&self) -> Hasher; } The purpose of this trait is to emphasize that the one piece of functionality for implementors is that new instances of `Hasher` can be created. This conceptually represents the two keys from which more instances of a `SipHasher` can be created, and a `HashState` is what's stored in a `HashMap`, not a `Hasher`. Implementors of custom hash algorithms should implement the `Hasher` trait, and only hash algorithms intended for use in hash maps need to implement or worry about the `HashState` trait. The entire module and `HashState` infrastructure remains `#[unstable]` due to it being recently redesigned, but some other stability decision made for the `std::hash` module are: * The `Writer` trait remains `#[experimental]` as it's intended to be replaced with an `io::Writer` (more details soon). * The top-level `hash` function is `#[unstable]` as it is intended to be generic over the hashing algorithm instead of hardwired to `SipHasher` * The inner `sip` module is now private as its one export, `SipHasher` is reexported in the `hash` module. And finally, a few changes were made to the default parameters on `HashMap`. * The `RandomSipHasher` default type parameter was renamed to `RandomState`. This renaming emphasizes that it is not a hasher, but rather just state to generate hashers. It also moves away from the name "sip" as it may not always be implemented as `SipHasher`. This type lives in the `std::collections::hash_map` module as `#[unstable]` * The associated `Hasher` type of `RandomState` is creatively called... `Hasher`! This concrete structure lives next to `RandomState` as an implemenation of the "default hashing algorithm" used for a `HashMap`. Under the hood this is currently implemented as `SipHasher`, but it draws an explicit interface for now and allows us to modify the implementation over time if necessary. There are many breaking changes outlined above, and as a result this commit is a: [breaking-change]

2015-01-02std: Stabilize the prelude moduleAlex Crichton-5/+5
This commit is an implementation of [RFC 503][rfc] which is a stabilization story for the prelude. Most of the RFC was directly applied, removing reexports. Some reexports are kept around, however: * `range` remains until range syntax has landed to reduce churn. * `Path` and `GenericPath` remain until path reform lands. This is done to prevent many imports of `GenericPath` which will soon be removed. * All `io` traits remain until I/O reform lands so imports can be rewritten all at once to `std::io::prelude::*`. This is a breaking change because many prelude reexports have been removed, and the RFC can be consulted for the exact list of removed reexports, as well as to find the locations of where to import them.

2014-12-29std: Second pass stabilization for `comm`Alex Crichton-1/+0
This commit is a second pass stabilization for the `std::comm` module, performing the following actions: * The entire `std::comm` module was moved under `std::sync::mpsc`. This movement reflects that channels are just yet another synchronization primitive, and they don't necessarily deserve a special place outside of the other concurrency primitives that the standard library offers. * The `send` and `recv` methods have all been removed. * The `send_opt` and `recv_opt` methods have been renamed to `send` and `recv`. This means that all send/receive operations return a `Result` now indicating whether the operation was successful or not. * The error type of `send` is now a `SendError` to implement a custom error message and allow for `unwrap()`. The error type contains an `into_inner` method to extract the value. * The error type of `recv` is now `RecvError` for the same reasons as `send`. * The `TryRecvError` and `TrySendError` types have had public reexports removed of their variants and the variant names have been tweaked with enum namespacing rules. * The `Messages` iterator is renamed to `Iter` This functionality is now all `#[stable]`: * `Sender` * `SyncSender` * `Receiver` * `std::sync::mpsc` * `channel` * `sync_channel` * `Iter` * `Sender::send` * `Sender::clone` * `SyncSender::send` * `SyncSender::try_send` * `SyncSender::clone` * `Receiver::recv` * `Receiver::try_recv` * `Receiver::iter` * `SendError` * `RecvError` * `TrySendError::{mod, Full, Disconnected}` * `TryRecvError::{mod, Empty, Disconnected}` * `SendError::into_inner` * `TrySendError::into_inner` This is a breaking change due to the modification of where this module is located, as well as the changing of the semantics of `send` and `recv`. Most programs just need to rename imports of `std::comm` to `std::sync::mpsc` and add calls to `unwrap` after a send or a receive operation. [breaking-change]

2014-12-15auto merge of #19448 : japaric/rust/binops-by-value, r=nikomatsakisbors-0/+44
- The following operator traits now take their arguments by value: `Add`, `Sub`, `Mul`, `Div`, `Rem`, `BitAnd`, `BitOr`, `BitXor`, `Shl`, `Shr`. This breaks all existing implementations of these traits. - The binary operation `a OP b` now "desugars" to `OpTrait::op_method(a, b)` and consumes both arguments. - `String` and `Vec` addition have been changed to reuse the LHS owned value, and to avoid internal cloning. Only the following asymmetric operations are available: `String + &str` and `Vec<T> + &[T]`, which are now a short-hand for the "append" operation. [breaking-change] --- This passes `make check` locally. I haven't touch the unary operators in this PR, but converting them to by value should be very similar to this PR. I can work on them after this gets the thumbs up. @nikomatsakis r? the compiler changes @aturon r? the library changes. I think the only controversial bit is the semantic change of the `Vec`/`String` `Add` implementation. cc #19148

2014-12-08librustc: Make `Copy` opt-in.Niko Matsakis-0/+9
This change makes the compiler no longer infer whether types (structures and enumerations) implement the `Copy` trait (and thus are implicitly copyable). Rather, you must implement `Copy` yourself via `impl Copy for MyType {}`. A new warning has been added, `missing_copy_implementations`, to warn you if a non-generic public type has been added that could have implemented `Copy` but didn't. For convenience, you may *temporarily* opt out of this behavior by using `#![feature(opt_out_copy)]`. Note though that this feature gate will never be accepted and will be removed by the time that 1.0 is released, so you should transition your code away from using it. This breaks code like: #[deriving(Show)] struct Point2D { x: int, y: int, } fn main() { let mypoint = Point2D { x: 1, y: 1, }; let otherpoint = mypoint; println!("{}{}", mypoint, otherpoint); } Change this code to: #[deriving(Show)] struct Point2D { x: int, y: int, } impl Copy for Point2D {} fn main() { let mypoint = Point2D { x: 1, y: 1, }; let otherpoint = mypoint; println!("{}{}", mypoint, otherpoint); } This is the backwards-incompatible part of #13231.

2014-10-09std: Convert statics to constantsAlex Crichton-17/+17
This commit repurposes most statics as constants in the standard library itself, with the exception of TLS keys which precisely have their own memory location as an implementation detail. This commit also rewrites the bitflags syntax to use `const` instead of `static`. All invocations will need to replace the word `static` with `const` when declaring flags.

Earlier commits have established a baseline of `experimental` stability for all crates under the facade (so their contents are considered experimental within libstd).

2014-05-15Make `from_bits` in `bitflags!` safe; add `from_bits_truncate`Aaron Turon-7/+30
Previously, the `from_bits` function in the `std::bitflags::bitflags` macro was marked as unsafe, as it did not check that the bits being converted actually corresponded to flags. This patch changes the function to check against the full set of possible flags and return an `Option` which is `None` if a non-flag bit is set. It also adds a `from_bits_truncate` function which simply zeros any bits not corresponding to a flag. This addresses the concern raised in https://github.com/mozilla/rust/pull/13897
2014-05-14auto merge of #14009 : jcmoyer/rust/bitflags-complement, r=alexcrichtonbors-1/+31
I feel that this is a very vital, missing piece of functionality. This adds on to #13072. Only bits used in the definition of the bitflag are considered for the universe set. This is a bit safer than simply inverting all of the bits in the wrapped value. ```rust bitflags!(flags Flags: u32 { FlagA = 0x00000001, FlagB = 0x00000010, FlagC = 0x00000100, FlagABC = FlagA.bits | FlagB.bits | FlagC.bits }) ... // `Not` implements set complement assert!(!(FlagB | FlagC) == FlagA); // `all` and `is_all` are the inverses of `empty` and `is_empty` assert!(Flags::all() - FlagA == !FlagA); assert!(FlagABC.is_all()); ```
