2018-03-31Auto merge of #49201 - Phlosioneer:add-trivial-size-hints, r=SimonSapinbors-0/+10
Implement some trivial size_hints for various iterators This also implements ExactSizeIterator where applicable. Addresses most of the Iterator traits mentioned in #23708. I intend to do more, but I don't want to make the PR too large.

2018-03-06Rollup merge of #47463 - bluss:fused-iterator, r=alexcrichtonkennytm-4/+4
Stabilize FusedIterator FusedIterator is a marker trait that promises that the implementing iterator continues to return `None` from `.next()` once it has returned `None` once (and/or `.next_back()`, if implemented). The effects of FusedIterator are already widely available through `.fuse()`, but with stable `FusedIterator`, stable Rust users can implement this trait for their iterators when appropriate. Closes #35602

2017-03-20Auto merge of #40281 - jimmycuadra:try-from-from-str, r=aturonbors-2/+2
Rename TryFrom's associated type and implement str::parse using TryFrom. Per discussion on the tracking issue, naming `TryFrom`'s associated type `Error` is generally more consistent with similar traits in the Rust ecosystem, and what people seem to assume it should be called. It also helps disambiguate from `Result::Err`, the most common "Err". See https://github.com/rust-lang/rust/issues/33417#issuecomment-269108968. `TryFrom<&str>` and `FromStr` are equivalent, so have the latter provide the former to ensure that. Using `TryFrom` in the implementation of `str::parse` means types that implement either trait can use it. When we're ready to stabilize `TryFrom`, we should update `FromStr` to suggest implementing `TryFrom<&str>` instead for new code. See https://github.com/rust-lang/rust/issues/33417#issuecomment-277175994 and https://github.com/rust-lang/rust/issues/33417#issuecomment-277253827. Refs #33417.

2017-03-13Remove function invokation parens from documentation links.Corey Farwell-10/+10

2016-09-28[breaking-change] std: change `encode_utf{8,16}()` to take a buffer and ↵tormol-119/+51

2016-08-29Implement TryFrom<u32> for charSimon Sapin-6/+29
For symmetry with From<char> for u32.
2016-08-29Implement From<char> for u32, and From<u8> for charSimon Sapin-0/+34
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-2/+3
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/

2016-05-26Explain the order of the enumeration itemsAndrea Canciani-0/+3
Simply a micro-optimization to reduce code size and to open up inlining opportunities.
2016-05-26Move length computation to `ExactSizeIterator` implsAndrea Canciani-24/+36
and reuse it in `size_hint`.
2016-05-26Implement `count` for `EscapeDefault` and `EscapeUnicode`Andrea Canciani-6/+7
Trivial implementation, as both are `ExactSizeIterator`s. Part of #24214.
2016-05-26`EscapeUnicode` and `EscapeDefault` are `ExactSizeIterator`sAndrea Canciani-0/+6
In #28662, `size_hint` was made exact for `EscapeUnicode` and `EscapeDefault`, but neither was marked as `ExactSizeIterator`.

2016-04-20Implement `last` for `EscapeUnicode`Andrea Canciani-0/+12
Part of #24214.
2016-04-19Auto merge of #31253 - ranma42:improve-unicode-iter-offset, r=brsonbors-20/+32
Improve computation of offset in `EscapeUnicode` Unify the computation of `offset` and use `leading_zeros` instead of manually scanning the bits. This PR removes some duplicated code and makes it a little simpler . The computation of `offset` is also faster, but it is unlikely to have an impact on actual code. (split from #31049)
2016-03-22std: Change `encode_utf{8,16}` to return iteratorsAlex Crichton-70/+119
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
