2015-01-06core: split into fmt::Show and fmt::StringSean McArthur-12/+55
fmt::Show is for debugging, and can and should be implemented for all public types. This trait is used with `{:?}` syntax. There still exists #[derive(Show)]. fmt::String is for types that faithfully be represented as a String. Because of this, there is no way to derive fmt::String, all implementations must be purposeful. It is used by the default format syntax, `{}`. This will break most instances of `{}`, since that now requires the type to impl fmt::String. In most cases, replacing `{}` with `{:?}` is the correct fix. Types that were being printed specifically for users should receive a fmt::String implementation to fix this. Part of #20013 [breaking-change]

2015-01-05Reformat metadata for exported macrosKeegan McAllister-1/+14
Instead of copy-pasting the whole macro_rules! item from the original .rs file, we serialize a separate name, attributes list, and body, the latter as pretty-printed TTs. The compilation of macro_rules! macros is decoupled somewhat from the expansion of macros in item position. This filters out comments, and facilitates selective imports.

2015-01-04serialize: Use assoc types + less old_orphan_checkAlex Crichton-22/+18
This commit moves the libserialize crate (and will force the hand of the rustc-serialize crate) to not require the `old_orphan_check` feature gate as well as using associated types wherever possible. Concretely, the following changes were made: * The error type of `Encoder` and `Decoder` is now an associated type, meaning that these traits have no type parameters. * The `Encoder` and `Decoder` type parameters on the `Encodable` and `Decodable` traits have moved to the corresponding method of the trait. This movement alleviates the dependency on `old_orphan_check` but implies that implementations can no longer be specialized for the type of encoder/decoder being implemented. Due to the trait definitions changing, this is a: [breaking-change]
2015-01-05Change `&` pat to only work with &T, and `&mut` with &mut T.Huon Wilson-1/+1
This implements RFC 179 by making the pattern `&<pat>` require matching against a variable of type `&T`, and introducing the pattern `&mut <pat>` which only works with variables of type `&mut T`. The pattern `&mut x` currently parses as `&(mut x)` i.e. a pattern match through a `&T` or a `&mut T` that binds the variable `x` to have type `T` and to be mutable. This should be rewritten as follows, for example, for &mut x in slice.iter() { becomes for &x in slice.iter() { let mut x = x; Due to this, this is a [breaking-change] Closes #20496.

2015-01-01std: Enforce Unicode in fmt::WriterAlex Crichton-1/+2
This commit is an implementation of [RFC 526][rfc] which is a change to alter the definition of the old `fmt::FormatWriter`. The new trait, renamed to `Writer`, now only exposes one method `write_str` in order to guarantee that all implementations of the formatting traits can only produce valid Unicode. [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0526-fmt-text-writer.md One of the primary improvements of this patch is the performance of the `.to_string()` method by avoiding an almost-always redundant UTF-8 check. This is a breaking change due to the renaming of the trait as well as the loss of the `write` method, but migration paths should be relatively easy: * All usage of `write` should move to `write_str`. If truly binary data was being written in an implementation of `Show`, then it will need to use a different trait or an altogether different code path. * All usage of `write!` should continue to work as-is with no modifications. * All usage of `Show` where implementations just delegate to another should continue to work as-is. [breaking-change] Closes #20352

2014-12-30Remove ExprSlice by hacking the compilerNick Cameron-1/+0
[breaking-change] The `mut` in slices is now redundant. Mutability is 'inferred' from position. This means that if mutability is only obvious from the type, you will need to use explicit calls to the slicing methods.

2014-12-22rollup merge of #20033: alexcrichton/deprecate-serialiseAlex Crichton-103/+106
This commit completes the deprecation story for the in-tree serialization library. The compiler will now emit a warning whenever it encounters `deriving(Encodable)` or `deriving(Decodable)`, and the library itself is now marked `#[unstable]` for when feature staging is enabled. All users of serialization can migrate to the `rustc-serialize` crate on crates.io which provides the exact same interface as the libserialize library in-tree. The new deriving modes are named `RustcEncodable` and `RustcDecodable` and require `extern crate "rustc-serialize" as rustc_serialize` at the crate root in order to expand correctly. To migrate all crates, add the following to your `Cargo.toml`: [dependencies] rustc-serialize = "0.1.1" And then add the following to your crate root: extern crate "rustc-serialize" as rustc_serialize; Finally, rename `Encodable` and `Decodable` deriving modes to `RustcEncodable` and `RustcDecodable`.
