2016-10-26Auto merge of #37315 - bluss:fold-more, r=alexcrichtonbors-0/+12
Implement Iterator::fold for .chain(), .cloned(), .map() and the VecDeque iterators. Chain can do something interesting here where it passes on the fold into its inner iterators. The lets the underlying iterator's custom fold() be used, and skips the regular chain logic in next. Also implement .fold() specifically for .map() and .cloned() so that any inner fold improvements are available through map and cloned. The same way, a VecDeque iterator fold can be turned into two slice folds. These changes lend the power of the slice iterator's loop codegen to VecDeque, and to chains of slice iterators, and so on. It's an improvement for .sum() and .product(), and other uses of fold.

2016-09-02Auto merge of #35856 - phimuemue:master, r=brsonbors-0/+14
Introduce max_by/min_by on iterators See https://github.com/rust-lang/rfcs/issues/1722 for reference. It seems that there is `min`, `max` (simple computation of min/max), `min_by_key`, `max_by_key` (min/max by comparing mapped values) but no `min_by` and `max_by` (min/max according to comparison function). However, e.g. on vectors or slices there is `sort`, `sort_by_key` and `sort_by`.
2016-09-01Auto merge of #35755 - SimonSapin:char_convert, r=alexcrichtonbors-0/+18
Implement std::convert traits for char This is motivated by avoiding the `as` operator, which sometimes silently truncates, and instead use conversions that are explicitly lossless and infallible. I’m less certain that `From<u8> for char` should be implemented: while it matches an existing behavior of `as`, it’s not necessarily the right thing to use for non-ASCII bytes. It effectively decodes bytes as ISO/IEC 8859-1 (since Unicode designed its first 256 code points to be compatible with that encoding), but that is not apparent in the API name.

2016-08-29Implement From<char> for u32, and From<u8> for charSimon Sapin-0/+8
These fit with other From implementations between integer types. This helps the coding style of avoiding the 'as' operator that sometimes silently truncates, and signals that these specific conversions are lossless and infaillible.

2016-07-23Escape fewer Unicode codepoints in `Debug` impl of `str`Tobias Bucher-3/+13
Use the same procedure as Python to determine whether a character is printable, described in [PEP 3138]. In particular, this means that the following character classes are escaped: - Cc (Other, Control) - Cf (Other, Format) - Cs (Other, Surrogate), even though they can't appear in Rust strings - Co (Other, Private Use) - Cn (Other, Not Assigned) - Zl (Separator, Line) - Zp (Separator, Paragraph) - Zs (Separator, Space), except for the ASCII space `' '` (`0x20`) This allows for user-friendly inspection of strings that are not English (e.g. compare `"\u{e9}\u{e8}\u{ea}"` to `"éèê"`). Fixes #34318. [PEP 3138]: https://www.python.org/dev/peps/pep-3138/

2016-06-03Auto merge of #33460 - shepmaster:16-bit-pointers, r=Aatchbors-0/+14
Support 16-bit pointers as well as i/usize I'm opening this pull request to get some feedback from the community. Although Rust doesn't support any platforms with a native 16-bit pointer at the moment, the [AVR-Rust][ar] fork is working towards that goal. Keeping this forked logic up-to-date with the changes in master has been onerous so I'd like to merge these changes so that they get carried along when refactoring happens. I do not believe this should increase the maintenance burden. This is based on the original work of Dylan McKay (@dylanmckay). [ar]: https://github.com/avr-rust/rust

2016-05-19Auto merge of #33103 - ranma42:escape-unicode-last, r=alexcrichtonbors-0/+33
Implement `last` for `EscapeUnicode` The implementation is quite trivial as the last character is always `'{'`. As a side-effect it also improves the implementation of `last` for `EscapeUnicode`. Part of #24214, split from #31049. Maybe this (and the other changes that I will split from #31049) should wait for a test like `ed_iterator_specializations` to be added. Would it be sufficient to do the same for each possible escape length?

2016-03-22std: Change `encode_utf{8,16}` to return iteratorsAlex Crichton-6/+8
Currently these have non-traditional APIs which take a buffer and report how much was filled in, but they're not necessarily ergonomic to use. Returning an iterator which *also* exposes an underlying slice shouldn't result in any performance loss as it's just a lazy version of the same implementation, and it's also much more ergonomic! cc #27784
