2019-02-26Auto merge of #58357 - sfackler:vectored-io, r=alexcrichtonbors-2/+31
Add vectored read and write support This functionality has lived for a while in the tokio ecosystem, where it can improve performance by minimizing copies. r? @alexcrichton
2019-02-20Rollup merge of #58553 - scottmcm:more-ihle, r=Centrilkennytm-1/+1
Use more impl header lifetime elision Inspired by seeing explicit lifetimes on these two: - https://doc.rust-lang.org/nightly/std/slice/struct.Iter.html#impl-FusedIterator - https://doc.rust-lang.org/nightly/std/primitive.u32.html#impl-Not And a follow-up to https://github.com/rust-lang/rust/pull/54687, that started using IHLE in libcore. Most of the changes in here fall into two big categories: - Removing lifetimes from common traits that can essentially never user a lifetime from an input (particularly `Drop`, `Debug`, and `Clone`) - Forwarding impls that are only possible because the lifetime doesn't matter (like `impl<R: Read + ?Sized> Read for &mut R`) I omitted things that seemed like they could be more controversial, like the handful of iterators that have a `Item: 'static` despite the iterator having a lifetime or the `PartialEq` implementations [where the flipped one cannot elide the lifetime](https://internals.rust-lang.org/t/impl-type-parameter-aliases/9403/2?u=scottmcm). I also removed two lifetimes that turned out to be completely unused; see https://github.com/rust-lang/rust/issues/41960#issuecomment-464557423

2019-02-13impl Deref/DerefMut for IoVec typesSteven Fackler-2/+2
Returning &'a mut [u8] was unsound, and we may as well just have them directly deref to their slices to make it easier to work with them.

2018-07-08rework `LineWriter` exampleAndy Russell-10/+24
The original example didn't check the return value of `write()`, didn't flush the writer, and didn't properly demonstrate the buffering. Fixes #51621.

2018-04-05Rollup merge of #49594 - mbrubeck:docs, r=steveklabnikkennytm-0/+12
Add some performance guidance to std::fs and std::io docs Adds more documentation about performance to various "read" functions in `fs` and `io`, and to `BufReader`/`BufWriter`, with the goal of helping developers choose the best option for a given task.

Fixes https://github.com/rust-lang/rust/issues/49233.
2018-03-18Add BufReader::bufferSteven Fackler-1/+29
This subsumes the need for an explicit is_empty function, and provides access to the buffered data itself which has been requested from time to time.

This is an API that allows types to indicate that they can be passed buffers of uninitialized memory which can improve performance.

* Since the switch to pulldown-cmark reference links need a blank line before the URLs. * Reference link references are not case sensitive. * Doc comments need to be indented uniformly otherwise rustdoc gets confused.

See #38644.
2016-11-28std: Fix partial writes in LineWriterAlex Crichton-13/+86
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
2016-11-10Remove one bounds check from BufReaderArthur Silva-1/+4
Otherwise the optimizer can't be sure that pos <= cap. Added a paranoid debug_assert to ensure correctness instead.

2016-10-05Fixed small typo in `BufRead` commentsRazican-1/+1
`BufRead` comments, in the `Seek` trait implementation, was talking about allocating 8 *ebibytes*. It was a typo, the correct unit is *exbibytes*, since *ebibytes* don't even exist. The calculation is correct, though.
