2014-12-22Insert coercions to fn pointer types required for the new typesNiko Matsakis-0/+1
post-unboxed-closure-conversion. This requires a fair amount of annoying coercions because all the `map` etc types are defined generically over the `F`, so the automatic coercions don't propagate; this is compounded by the need to use `let` and not `as` due to stage0. That said, this pattern is to a large extent temporary and unusual.
2014-12-22Fix fallout from changes. In cases where stage0 compiler is needed, weNiko Matsakis-0/+1
cannot use an `as` expression to coerce, so I used a one-off function instead (this is a no-op in stage0, but in stage1+ it triggers coercion from the fn pointer to the fn item type).

2014-12-21std: Stabilize the std::str moduleAlex Crichton-880/+130
This commit starts out by consolidating all `str` extension traits into one `StrExt` trait to be included in the prelude. This means that `UnicodeStrPrelude`, `StrPrelude`, and `StrAllocating` have all been merged into one `StrExt` exported by the standard library. Some functionality is currently duplicated with the `StrExt` present in libcore. This commit also currently avoids any methods which require any form of pattern to operate. These functions will be stabilized via a separate RFC. Next, stability of methods and structures are as follows: Stable * from_utf8_unchecked * CowString - after moving to std::string * StrExt::as_bytes * StrExt::as_ptr * StrExt::bytes/Bytes - also made a struct instead of a typedef * StrExt::char_indices/CharIndices - CharOffsets was renamed * StrExt::chars/Chars * StrExt::is_empty * StrExt::len * StrExt::lines/Lines * StrExt::lines_any/LinesAny * StrExt::slice_unchecked * StrExt::trim * StrExt::trim_left * StrExt::trim_right * StrExt::words/Words - also made a struct instead of a typedef Unstable * from_utf8 - the error type was changed to a `Result`, but the error type has yet to prove itself * from_c_str - this function will be handled by the c_str RFC * FromStr - this trait will have an associated error type eventually * StrExt::escape_default - needs iterators at least, unsure if it should make the cut * StrExt::escape_unicode - needs iterators at least, unsure if it should make the cut * StrExt::slice_chars - this function has yet to prove itself * StrExt::slice_shift_char - awaiting conventions about slicing and shifting * StrExt::graphemes/Graphemes - this functionality may only be in libunicode * StrExt::grapheme_indices/GraphemeIndices - this functionality may only be in libunicode * StrExt::width - this functionality may only be in libunicode * StrExt::utf16_units - this functionality may only be in libunicode * StrExt::nfd_chars - this functionality may only be in libunicode * StrExt::nfkd_chars - this functionality may only be in libunicode * StrExt::nfc_chars - this functionality may only be in libunicode * StrExt::nfkc_chars - this functionality may only be in libunicode * StrExt::is_char_boundary - naming is uncertain with container conventions * StrExt::char_range_at - naming is uncertain with container conventions * StrExt::char_range_at_reverse - naming is uncertain with container conventions * StrExt::char_at - naming is uncertain with container conventions * StrExt::char_at_reverse - naming is uncertain with container conventions * StrVector::concat - this functionality may be replaced with iterators, but it's not certain at this time * StrVector::connect - as with concat, may be deprecated in favor of iterators Deprecated * StrAllocating and UnicodeStrPrelude have been merged into StrExit * eq_slice - compiler implementation detail * from_str - use the inherent parse() method * is_utf8 - call from_utf8 instead * replace - call the method instead * truncate_utf16_at_nul - this is an implementation detail of windows and does not need to be exposed. * utf8_char_width - moved to libunicode * utf16_items - moved to libunicode * is_utf16 - moved to libunicode * Utf16Items - moved to libunicode * Utf16Item - moved to libunicode * Utf16Encoder - moved to libunicode * AnyLines - renamed to LinesAny and made a struct * SendStr - use CowString<'static> instead * str::raw - all functionality is deprecated * StrExt::into_string - call to_string() instead * StrExt::repeat - use iterators instead * StrExt::char_len - use .chars().count() instead * StrExt::is_alphanumeric - use .chars().all(..) * StrExt::is_whitespace - use .chars().all(..) Pending deprecation -- while slicing syntax is being worked out, these methods are all #[unstable] * Str - while currently used for generic programming, this trait will be replaced with one of [], deref coercions, or a generic conversion trait. * StrExt::slice - use slicing syntax instead * StrExt::slice_to - use slicing syntax instead * StrExt::slice_from - use slicing syntax instead * StrExt::lev_distance - deprecated with no replacement Awaiting stabilization due to patterns and/or matching * StrExt::contains * StrExt::contains_char * StrExt::split * StrExt::splitn * StrExt::split_terminator * StrExt::rsplitn * StrExt::match_indices * StrExt::split_str * StrExt::starts_with * StrExt::ends_with * StrExt::trim_chars * StrExt::trim_left_chars * StrExt::trim_right_chars * StrExt::find * StrExt::rfind * StrExt::find_str * StrExt::subslice_offset

followed by a semicolon. This allows code like `vec![1i, 2, 3].len();` to work. This breaks code that uses macros as statements without putting semicolons after them, such as: fn main() { ... assert!(a == b) assert!(c == d) println(...); } It also breaks code that uses macros as items without semicolons: local_data_key!(foo) fn main() { println("hello world") } Add semicolons to fix this code. Those two examples can be fixed as follows: fn main() { ... assert!(a == b); assert!(c == d); println(...); } local_data_key!(foo); fn main() { println("hello world") } RFC #378. Closes #18635.

2014-12-08librustc: Make `Copy` opt-in.Niko Matsakis-1/+8
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. Part of RFC #3. [breaking-change]

This commit is an implementation of [RFC 240][rfc] when applied to the standard library. It primarily deprecates the entirety of `string::raw`, `vec::raw`, `slice::raw`, and `str::raw` in favor of associated functions, methods, and other free functions.

2014-11-21unicode: Rename UnicodeChar::is_digit to is_numericBrian Anderson-7/+7
'Numeric' is the proper name of the unicode character class, and this frees up the word 'digit' for ascii use in libcore. Since I'm going to rename `Char::is_digit_radix` to `is_digit`, I am not leaving a deprecated method in place, because that would just cause name clashes, as both `Char` and `UnicodeChar` are in the prelude.

2014-11-18rollup merge of #18911: canndrew/slice_shift_charJakub Bukaj-9/+9
`slice_shift_char` splits a `str` into it's leading `char` and the remainder of the `str`. Currently, it returns a `(Option<char>, &str)` such that: "bar".slice_shift_char() => (Some('b'), "ar") "ar".slice_shift_char() => (Some('a'), "r") "r".slice_shift_char() => (Some('r'), "") "".slice_shift_char() => (None, "") This is a little odd. Either a `str` can be split into both a head and a tail or it cannot. So the return type should be `Option<(char, &str)>`. With the current behaviour, in the case of the empty string, the `str` returned is meaningless - it is always the empty string. This PR changes `slice_shift_char` so that: "bar".slice_shift_char() => Some(('b', "ar")) "ar".slice_shift_char() => Some(('a', "r")) "r".slice_shift_char() => Some(('r', "")) "".slice_shift_char() => None

This implements a considerable portion of rust-lang/rfcs#369 (tracked in #18640). Some interpretations had to be made in order to get this to work. The breaking changes are listed below: [breaking-change] - `core::num::{Num, Unsigned, Primitive}` have been deprecated and their re-exports removed from the `{std, core}::prelude`. - `core::num::{Zero, One, Bounded}` have been deprecated. Use the static methods on `core::num::{Float, Int}` instead. There is no equivalent to `Zero::is_zero`. Use `(==)` with `{Float, Int}::zero` instead. - `Signed::abs_sub` has been moved to `std::num::FloatMath`, and is no longer implemented for signed integers. - `core::num::Signed` has been removed, and its methods have been moved to `core::num::Float` and a new trait, `core::num::SignedInt`. The methods now take the `self` parameter by value. - `core::num::{Saturating, CheckedAdd, CheckedSub, CheckedMul, CheckedDiv}` have been removed, and their methods moved to `core::num::Int`. Their parameters are now taken by value. This means that - `std::time::Duration` no longer implements `core::num::{Zero, CheckedAdd, CheckedSub}` instead defining the required methods non-polymorphically. - `core::num::{zero, one, abs, signum}` have been deprecated. Use their respective methods instead. - The `core::num::{next_power_of_two, is_power_of_two, checked_next_power_of_two}` functions have been deprecated in favor of methods defined a new trait, `core::num::UnsignedInt` - `core::iter::{AdditiveIterator, MultiplicativeIterator}` are now only implemented for the built-in numeric types. - `core::iter::{range, range_inclusive, range_step, range_step_inclusive}` now require `core::num::Int` to be implemented for the type they a re parametrized over.

2014-11-06Prelude: rename and consolidate extension traitsAaron Turon-7/+6
This commit renames a number of extension traits for slices and string slices, now that they have been refactored for DST. In many cases, multiple extension traits could now be consolidated. Further consolidation will be possible with generalized where clauses. The renamings are consistent with the [new `-Prelude` suffix](https://github.com/rust-lang/rfcs/pull/344). There are probably a few more candidates for being renamed this way, but that is left for API stabilization of the relevant modules. Because this renames traits, it is a: [breaking-change] However, I do not expect any code that currently uses the standard library to actually break. Closes #17917
