2017-03-24Document Cursor::new position is 0Stepan Koltsov-0/+4
... even if contained `Vec` is not empty. E. g. for ``` let v = vec![10u8, 20]; let mut c = io::Cursor::new(v); c.write_all(b"aaaa").unwrap(); println!("{:?}", c.into_inner()); ``` result is ``` [97, 97, 97, 97] ``` and not ``` [10, 20, 97, 97, 97, 97] ```

2017-03-01Only keep one copy of the UTF8_CHAR_WIDTH table.Simon Sapin-1/+1
… instead of one of each of libcore and libstd_unicode. Move the `utf8_char_width` function to `core::str` under the `str_internals` unstable feature.

2017-01-13Change `to_owned` to `to_string` in docsStjepan Glavina-2/+2
We should teach conversion from `str` to `String` using `to_string` rather than the legacy `to_owned`.
2016-12-24Rollup merge of #38505 - estebank:why-lines, r=frewsxcvSteve Klabnik-0/+6
Docs: Explain why/when `.lines()` returns an error Fix #37744.
2016-12-24Auto merge of #38062 - alexcrichton:fix-line-writer, r=brsonbors-13/+86
std: Fix partial writes in LineWriter Previously the `LineWriter` could successfully write some bytes but then fail to report that it has done so. Additionally, an erroneous flush after a successful write was permanently ignored. This commit fixes these two issues by (a) maintaining a `need_flush` flag to indicate whether a flush should be the first operation in `LineWriter::write` and (b) avoiding returning an error once some bytes have been successfully written. Closes #37807

2016-11-30Move small-copy optimization into <&[u8] as Read>Ruud van Asseldonk-2/+20
Based on the discussion in https://github.com/rust-lang/rust/pull/37573, it is likely better to keep this limited to std::io, instead of modifying a function which users expect to be a memcpy.
2016-11-30Move small-copy optimization into copy_from_sliceRuud van Asseldonk-15/+3
Ultimately copy_from_slice is being a bottleneck, not io::Cursor::read. It might be worthwhile to move the check here, so more places can benefit from it.
2016-11-30Add small-copy optimization for io::CursorRuud van Asseldonk-3/+15
During benchmarking, I found that one of my programs spent between 5 and 10 percent of the time doing memmoves. Ultimately I tracked these down to single-byte slices being copied with a memcopy in io::Cursor::read(). Doing a manual copy if only one byte is requested can speed things up significantly. For my program, this reduced the running time by 20%. Why special-case only a single byte, and not a "small" slice in general? I tried doing this for slices of at most 64 bytes and of at most 8 bytes. In both cases my test program was significantly slower.

2016-11-04Auto merge of #37037 - Mark-Simulacrum:stack-error, r=alexcrichtonbors-21/+48
Add conversions from `io:ErrorKind` to `io::Error` Filing to help with discussion around the possibility of doing this. Current changes are clearly backwards incompatible, but I think adding a new function (with a bikeshed on naming) like `Error::new_str` should be possible (or some other way of specializing the string error message case) to fix #36658.

More refactoring to obey platform abstraction lint The most interesting things here are moving `std/sys/common` to `std/sys_common`, and `std/num/{f32,f64}.rs` to `std/{f32,f64}.rs`, and adding more documentation to `std/lib.rs`. r? @alexcrichton

2016-10-31Changed most vec! invocations to use square bracesiirelu-6/+6
Most of the Rust community agrees that the vec! macro is clearer when called using square brackets [] instead of regular brackets (). Most of these ocurrences are from before macros allowed using different types of brackets. There is one left unchanged in a pretty-print test, as the pretty printer still wants it to have regular brackets.
2016-10-27Add documentation for Read, Write impls for slices and VecUlrik Sverdrup-0/+11
The Write impls for &[u8] and Vec<u8> are quite different, and we need this to be reflected in the docs. These documentation comments will be visible on the respective type's page in the trait impls section.
