We discussed coercions for `if` and `match` expressions. `if` seems to work already, was there some specific behaviour which wasn't working?
There is currently no way to specify the stability level for a trait
impl produced by `deriving`. This patch is a stopgap solution that:
* Turns of stability inheritance for trait impls, and
* Uses the stability level of the *trait* if no level is directly
specified.
That is, manual trait impls may still provide a directly stability
level, but `deriving` will use the level of the trait. While not a
perfect solution, it should be good enough for 1.0 API stabilization, as
we will like *remove* any unwanted impls outright.
This narrows the definition of nested returns such that only when the
outer return has a chance of being executed (due to the inner return
being conditional) do we mark the function as having nested returns.
Fixes#19684
If you configure with `--disable-docs`, the `doc` directory does not get generated, so
`cp -r doc dist/` fails when you `make dist{,-tar-bins,-doc}` or `make install`
Fix `make TAGS.emacs`.
@nikomatsakis has been complaining to me about this. (I had not noticed since I drive `ctags` with a separate script.)
(Suitable for a rollup build.)
This is to encourage the use of the sugary syntax instead of the `<>` syntax, which will not be usable post-1.0. Rustdoc [still uses the `<>` syntax](https://github.com/rust-lang/rust/issues/19909), so if a rustdoc wizard is looking for something to do, it would be nice to use the parenthetical syntax there as well. (I tried to patch rustdoc as well, but failed…)
Fixes some tuple indexing deprecation warnings. Didn't test. Don't see how it could fail unless I need to modify a makefile somewhere...

Was testing rustup on a very minimal Debian installation and got errors during the install process (error occurred in `install.sh` of the Rust nightly.)
Noticed that Rustup was downloading the i686 nightly instead of x86-64. Installing `file` fixed the problem, and this patch adds the probe to ensure file is installed before attempting to use it.
There may still be an issue with the i686 installation, I did not investigate further.
Added -Z print-region-graph debugging option; produces graphviz visualization of region inference constraint graph.
Optionally uses environment variables `RUST_REGION_GRAPH=<path_template>` and `RUST_REGION_GRAPH_NODE=<node-id>` to select which file to output to and which AST node to print.
Relax some of the bounds on the decoder methods back to FnMut to help accomodate
some more flavorful variants of decoders which may need to run the closure more
than once when it, for example, attempts to find the first successful enum to
decode.
In US english, "that" is used in restrictive clauses in place of
"which", and often affects the meaning of sentences.
In UK english and many dialects, no distinction is
made.
While Rust devs want to avoid unproductive pedanticism, it is worth at
least being uniform in documentation such as:
http://doc.rust-lang.org/std/iter/index.html
and also in cases where correct usage of US english clarifies the
sentence.
Includes a fix for a small mistake in `fn insert` which is caught by test_insert for len=15, but not len=7.
Part of #18424

This test would read with a timeout and then send a UDP message, expecting the
message to be received. The receiving port, however, was bound in the child
thread so it could be the case that the timeout and send happens before the
child thread runs. To remedy this we just bind the port before the child thread
runs, moving it into the child later on.
cc #19120
- Change long inline code to code block
- Replace double-hyphens with en dash
- Miscellaneous rephrasings for clarity
**Edit**: Trivial `commit --amend` to change the commit message slightly.
This commit takes a second pass through the `std::option` module to fully
stabilize any lingering methods inside of it.
These items were made stable as-is
* Some
* None
* as_mut
* expect
* unwrap
* unwrap_or
* unwrap_or_else
* map
* map_or
* map_or_else
* and_then
* or_else
* unwrap_or_default
* Default implementation
* FromIterator implementation
* Copy implementation
These items were made stable with modifications
* iter - now returns a struct called Iter
* iter_mut - now returns a struct called IterMut
* into_iter - now returns a struct called IntoIter, Clone is never implemented
This is a breaking change due to the modifications to the names of the iterator
types returned. Code referencing the old names should updated to referencing the
newer names instead. This is also a breaking change due to the fact that
`IntoIter` no longer implements the `Clone` trait.
These items were explicitly not stabilized
* as_slice - waiting on indexing conventions
* as_mut_slice - waiting on conventions with as_slice as well
* cloned - the API was still just recently added
* ok_or - API remains experimental
* ok_or_else - API remains experimental
[breaking-change]
