Optimize string comparison by using memcmp

2015-09-10T23:46:59+00:00

llvm seems to be having some trouble optimizing the iterator-based string comparsion method into some equivalent to memcmp. This explicitly calls out to the memcmp intrinisic in order to allow llvm to generate better code. In some manual benchmarking, this memcmp-based approach is 20 times faster than the iterator approach.

some more clippy-based improvements

std: Account for CRLF in {str, BufRead}::lines

2015-09-04T06:01:41+00:00

This commit is an implementation of [RFC 1212][rfc] which tweaks the behavior of the `str::lines` and `BufRead::lines` iterators. Both iterators now account for `\r\n` sequences in addition to `\n`, allowing for less surprising behavior across platforms (especially in the `BufRead` case). Splitting *only* on the `\n` character can still be achieved with `split('\n')` in both cases. The `str::lines_any` function is also now deprecated as `str::lines` is a drop-in replacement for it. [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/1212-line-endings.md Closes #28032

Auto merge of #28101 - ijks:24214-str-bytes, r=alexcrichton

2015-08-31T09:15:55+00:00

Specifically, `count`, `last`, and `nth` are implemented to use the methods of the underlying slice iterator. Partially closes #24214.

Add overrides to iterator methods for `str::Bytes`
