2017-10-18Implement is_empty() for BufReaderJonathan Behrens-0/+25
2017-08-15use field init shorthand EVERYWHEREZack M. Davis-1/+1
Like #43008 (f668999), but _much more aggressive_.
2017-07-20Remove mut where possibleEvan Cameron-10/+10
2017-07-09Add warning to BufWriter documentationJohn Gallagher-1/+5
2017-06-20Add `Read::initializer`.Steven Fackler-6/+16
This is an API that allows types to indicate that they can be passed buffers of uninitialized memory which can improve performance.
2017-04-06Fix Markdown issues in the docsOliver Middleton-8/+9
* 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.
2017-01-22libstd: replace all `try!` with `?` in documentation examplesUtkarsh Kukreti-16/+16
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.
2016-09-30Ignore lots and lots of std tests on emscriptenBrian Anderson-0/+1
2016-09-21Fix outdated Doc Comment on BufReader::seekChristopher Serr-2/+2
A long time ago non-panicking `unwrap` methods were renamed to `into_inner` in this Pull Request: https://github.com/rust-lang/rust/pull/19149 Looks like this doc comment was not updated however.
2016-09-11Remove unnecessary `cmp::min` from BufWriter::writeRichard Janis Goldschmidt-2/+1
The first branch of the if statement already checks if `buf.len() >= self.buf.capacity()`, which makes the `cmp::min(buf.len(), self.buf.capacity())` redundant: the result will always be `buf.len()`. Therefore, we can pass the `buf` slice directly into `Write::write`.
2016-08-24Use `#[prelude_import]` in `libstd`.Jeffrey Seyfried-2/+0
2016-05-09Utilize `Result::unwrap_err` in more places.Corey Farwell-1/+1

Automated conversion using the untry tool [1] and the following command: ``` $ find -name '*.rs' -type f | xargs untry ``` at the root of the Rust repo. [1]: https://github.com/japaric/untry
2016-03-07Add test case for #32085Steven Allen-0/+28
2016-03-07Never return an error after a partial writeSteven Allen-2/+4
If LineWriter fails to flush, return the number of bytes written instead of an error. Fixes #32085
2016-01-26Fix warnings during testsAlex Crichton-2/+2
The deny(warnings) attribute is now enabled for tests so we need to weed out these warnings as well.
2016-01-22Auto merge of #31070 - sfackler:bufreader-box-slice, r=alexcrichtonbors-2/+2
Saves a word, and also prevents the impl from accidentally changing the buffer length. r? @alexcrichton

Saves a word, and also prevents the impl from accidentally changing the buffer length.
2016-01-20Don't flush in BufWriter destructor after a panic in writeSteven Fackler-3/+40
We don't want to write the same data twice. Closes #30888
2016-01-12Remove dead `InternalBufWriter` implementationAndrea Canciani-15/+0
In 8d90d3f36871a00023cc1f313f91e351c287ca15 `BufStream`, the only consumer of `InternalBufWriter`, was removed. As implied by the name, this type is private, hence it is currently dead code.

2015-08-12Remove all unstable deprecated functionalityAlex Crichton-148/+1
This commit removes all unstable and deprecated functions in the standard library. A release was recently cut (1.3) which makes this a good time for some spring cleaning of the deprecated functions.
2015-07-29Rollup merge of #27341 - steveklabnik:remove_warning, r=alexcrichtonSteve Klabnik-4/+0
This isn't a standard header, and the other docs don't use it, so let's remove it.
2015-07-27Remove warning header for consistencySteve Klabnik-4/+0
This isn't a standard header, and the other docs don't use it, so let's remove it.
2015-07-27std: Deprecate a number of unstable featuresAlex Crichton-1/+1
Many of these have long since reached their stage of being obsolete, so this commit starts the removal process for all of them. The unstable features that were deprecated are: * cmp_partial * fs_time * hash_default * int_slice * iter_min_max * iter_reset_fuse * iter_to_vec * map_in_place * move_from * owned_ascii_ext * page_size * read_and_zero * scan_state * slice_chars * slice_position_elem * subslice_offset

2015-07-08Auto merge of #26849 - bluss:read-to-end-memset, r=alexcrichtonbors-4/+1
Improve zerofill in Vec::resize and Read::read_to_end We needed a more efficient way to zerofill the vector in read_to_end. This to reduce the memory intialization overhead to a minimum. Use the implementation of `std::vec::from_elem` (used for the vec![] macro) for Vec::resize as well. For simple element types like u8, this compiles to memset, so it makes Vec::resize much more efficient.
2015-07-08io: Simplify BufReader::with_capacityUlrik Sverdrup-4/+1
Use the vec![] macro directly to create a sized, zeroed vector. This should result in a big speedup when creating BufReader, because vec![0; cap] compiles to a memset call, while the previous extend code currently did not.
2015-07-05std: small doc fixes for BufReader and BufWriterGeorg Brandl-8/+8

2015-06-17std: Deprecate the io::BufStream typeAlex Crichton-0/+4
Questions about the utility of this type has caused it to move to crates.io in the `bufstream` crate, so this type can be deprecated.
2015-05-19Add example code and cross-link to BufReader docsMatt Brubeck-0/+18
2015-05-05Auto merge of #25009 - alexcrichton:less-buffered-stream, r=aturonbors-10/+18
As pointed out in #17136 the semantics of a `BufStream` aren't always what one expects, and it looks like other [languages like C#][c-sharp] implement a buffered stream with only one underlying buffer. For now this commit destabilizes the primitive in the `std::io` module to give us some more time in figuring out what to do with it.

2015-05-01Auto merge of #25006 - alexcrichton:unstable-indexing, r=aturonbors-3/+3
These implementations were intended to be unstable, but currently the stability attributes cannot handle a stable trait with an unstable `impl` block. This commit also audits the rest of the standard library for explicitly-`#[unstable]` impl blocks. No others were removed but some annotations were changed to `#[stable]` as they're defacto stable anyway. One particularly interesting `impl` marked `#[stable]` as part of this commit is the `Add<&[T]>` impl for `Vec<T>`, which uses `push_all` and implicitly clones all elements of the vector provided. Closes #24791 [breaking-change]
