This moves chars() and lines() out of Buffer and into separate traits (CharsBuffer and LinesBuffer respectively) - this matches the pattern used for bytes() on Reader (with BytesReader).
(I came across this when I wanted a trait object of a Buffer, so that I could use read_line(); rustc errors about std::io::Buffer not being object-safe.)
[breaking-change]
Any uses of Buffer::lines() will need to use the new trait std::io::LinesBuffer.
The same is true for Buffer::chars() with std::io::CharsBuffer.
not in hardcoded libdir path. If there was no LIBDIR provided
during configuration fallback to hardcoded paths.
Thanks to Jan Niklas Hasse for solution and to Alex Crichton for improvements.
Closes#11671
This test was somewhat sketchy already with a `loop` around `write`, so this
just adds some explicit synchronization to only call `write` once and guarantee
that the error happens.
Closes#18900
This commit slightly tweaks the counting of impl blocks and structs for
the stability summary (so that the block itself isn't counted for
inherent impls, and the fields aren't counted for structs).
A recent change turned off inheritance for the #[stable] by default, but
failed to catch all the cases where this was being used in std. This
patch fixes that problem.
I found some occurrences of "failure" and "fails" in the documentation. I changed them to "panics" if it means a task panic. Otherwise I left it as is, or changed it to "errors" to clearly distinguish them.
Also, I made a minor fix that is breaking the layout of a module page. "Example" is shown in an irrelevant place from the following page: http://doc.rust-lang.org/std/os/index.html
This was a simple case of substitutions being applied inconsistently. I haven't investigated why type parameters are actually showing up in the closure type here, but trans needs to handle them correctly in any case.
The examples in the documentation for syntax::ext::deriving::encodable
are outdated, and do not work. To fix this, the following changes are
applied:
- emit_field() -> emit_struct_field()
- read_field() -> read_struct_field()
- Use Result to report errors
- Add the mut keyword to Encoder/Decoder
- Prefer Encodable::encode() to emit_uint
It seems odd that the `AsRefReader`/`AsRefWriter` have the single method `by_ref()`. This creates the new traits `ByRefReader`/`ByRefWriter` and deprecates the old traits.
