2018-09-12Rollup merge of #54046 - snaedis:issue-48022, r=steveklabnikkennytm-1/+2
Update documentation for fill_buf in std::io::BufRead Brings the documentation in line with the BufReader implementation. Fixes #48022. This is my first PR, and I think the `E-easy` label is very cool, as so is the practice of describing the fix but leaving it for someone else; it really makes it a lot less intimidating to get started with something!

Implement always-fallible TryFrom for usize/isize conversions that are infallible on some platforms This reverts commit 837d6c70233715a0ae8e15c703d40e3046a2f36a "Remove TryFrom impls that might become conditionally-infallible with a portability lint". This fixes #49415 by adding (restoring) missing `TryFrom` impls for integer conversions to or from `usize` or `isize`, by making them always fallible at the type system level (that is, with `Error=TryFromIntError`) even though they happen to be infallible on some platforms (for some values of `size_of::<usize>()`). They had been removed to allow the possibility to conditionally having some of them be infallible `From` impls instead, depending on the platforms, and have the [portability lint](https://github.com/rust-lang/rfcs/pull/1868) warn when they are used in code that is not already opting into non-portability. For example `#[allow(some_lint)] usize::from(x: u64)` would be valid on code that only targets 64-bit platforms. This PR gives up on this possiblity for two reasons: * Based on discussion with @aturon, it seems that the portability lint is not happening any time soon. It’s better to have the conversions be available *at all* than keep blocking them for so long. Portability-lint-gated platform-specific APIs can always be added separately later. * For code that is fine with fallibility, the alternative would force it to opt into "non-portability" even though there would be no real portability issue.

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.

2018-01-30std: use more portable error number in from_raw_os_error docsJames Cowgill-4/+4
On MIPS, error number 98 is not EADDRINUSE (it is EPROTOTYPE). To fix the resulting test failure this causes, use a more portable error number in the example documentation. EINVAL shold be more reliable because it was defined in the original Unix as 22 so hopefully most derivatives have defined it the same way.
