2017-09-29Implement Error trait for TryFromSliceErrorNikolai Vazquez-0/+15
2017-09-21Implement TryFrom for array reference typesNikolai Vazquez-0/+34
There are many cases where a buffer with a static compile-time size is preferred over a slice with a dynamic size. This allows for performing a checked conversion from &[T] to &[T; N]. This may also lead to compile-time optimizations involving [T; N] such as loop unrolling.

2017-08-22Auto merge of #43690 - scalexm:issue-28229, r=nikomatsakisbors-0/+1
Generate builtin impls for `Clone` This fixes a long-standing ICE and limitation where some builtin types implement `Copy` but not `Clone` (whereas `Clone` is a super trait of `Copy`). However, this PR has a few side-effects: * `Clone` is now marked as a lang item. * `[T; N]` is now `Clone` if `T: Clone` (currently, only if `T: Copy` and for `N <= 32`). * `fn foo<'a>() where &'a mut (): Clone { }` won't compile anymore because of how bounds for builtin traits are handled (e.g. same thing currently if you replace `Clone` by `Copy` in this example). Of course this function is unusable anyway, an error would pop as soon as it is called. Hence, I'm wondering wether this PR would need an RFC... Also, cc-ing @nikomatsakis, @arielb1. Related issues: #28229, #24000.

2015-12-07Revert "PR #30130 Implement `Clone` for more arrays"Ulrik Sverdrup-28/+8
This reverts commit e22a64e8d8d4da46c74f878ce1c23ad1c88982e8. This caused a regression such that types like `[[u8; 256]; 4]` no longer implemented Clone. This previously worked due to Clone for `[T; N]` (N in 0 to 32) being implemented for T: Copy. Due to fixed size arrays not implementing Clone for sizes above 32, the new implementation requiring T: Clone would not allow `[[u8; 256]; 4]` to be Clone.

Do so by using the fact that fixed size arrays (like `[u8; 8]` can be coerced to slices `&[u8]`, this is expressed through the trait `Unsize<[T]>` that all fixed size arrays implement.

2015-07-20std: Create separate docs for the primitivesBrian Anderson-1/+2
Having the primitive and module docs derived from the same source causes problems, primarily that they can't contain hyperlinks cross-referencing each other. This crates dedicated private modules in `std` to document the primitive types, then for all primitives that have a corresponding module, puts hyperlinks in moth the primitive docs and the module docs cross-linking each other. This should help clear up confusion when readers find themselves on the wrong page.
2015-06-17core: Split apart the global `core` featureAlex Crichton-8/+3
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

2015-02-18std: Stabilize the `hash` moduleAlex Crichton-2/+10
This commit is an implementation of [RFC 823][rfc] which is another pass over the `std::hash` module for stabilization. The contents of the module were not entirely marked stable, but some portions which remained quite similar to the previous incarnation are now marked `#[stable]`. Specifically: [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0823-hash-simplification.md * `std::hash` is now stable (the name) * `Hash` is now stable * `Hash::hash` is now stable * `Hasher` is now stable * `SipHasher` is now stable * `SipHasher::new` and `new_with_keys` are now stable * `Hasher for SipHasher` is now stable * Many `Hash` implementations are now stable All other portions of the `hash` module remain `#[unstable]` as they are less commonly used and were recently redesigned. This commit is a breaking change due to the modifications to the `std::hash` API and more details can be found on the [RFC][rfc]. Closes #22467 [breaking-change]

2015-01-20std: Rename Show/String to Debug/DisplayAlex Crichton-3/+3
This commit is an implementation of [RFC 565][rfc] which is a stabilization of the `std::fmt` module and the implementations of various formatting traits. Specifically, the following changes were performed: [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0565-show-string-guidelines.md * The `Show` trait is now deprecated, it was renamed to `Debug` * The `String` trait is now deprecated, it was renamed to `Display` * Many `Debug` and `Display` implementations were audited in accordance with the RFC and audited implementations now have the `#[stable]` attribute * Integers and floats no longer print a suffix * Smart pointers no longer print details that they are a smart pointer * Paths with `Debug` are now quoted and escape characters * The `unwrap` methods on `Result` now require `Display` instead of `Debug` * The `Error` trait no longer has a `detail` method and now requires that `Display` must be implemented. With the loss of `String`, this has moved into libcore. * `impl<E: Error> FromError<E> for Box<Error>` now exists * `derive(Show)` has been renamed to `derive(Debug)`. This is not currently warned about due to warnings being emitted on stage1+ While backwards compatibility is attempted to be maintained with a blanket implementation of `Display` for the old `String` trait (and the same for `Show`/`Debug`) this is still a breaking change due to primitives no longer implementing `String` as well as modifications such as `unwrap` and the `Error` trait. Most code is fairly straightforward to update with a rename or tweaks of method calls. [breaking-change] Closes #21436
