The word is repeated twice in the message like:
error: obsolete syntax: `:`, `&mut:`, or `&:` syntax
This removes the word syntax that appears in messages after the second colon (:).

The 'stable_features' lint helps people progress from unstable to
stable Rust by telling them when they no longer need a `feature`
attribute because upstream Rust has declared it stable.
This compares to the existing 'unstable_features' lint, which is used
to implement feature staging, and triggers on *any* use
of `#[feature]`.

The spelling corrections were made in both documentation comments and

This can be considered partial work on #8256.
The main observable change: macro expansion sometimes results in spans where `lo > hi`; so for now, when we have such a span, do not attempt to return a snippet result.
(Longer term, we might think about whether we could still present a snippet for the cases where this arises, e.g. perhaps by showing the whole macro as the snippet, assuming that is the sole cause of such spans; or by somehow looking up the closest AST node that holds both `lo` and `hi`, and showing that.)
As a drive-by, revised the API to return a `Result` rather than an `Option`, with better information-packed error value that should help us (and maybe also our users) identify the causes of such problems in the future. Ideally the call-sites that really want an actual snippet would be updated to catch the newly added `Err` case and print something meaningful about it, but that is not part of this PR.

Implement step 1 of rust-lang/rfcs#702
Allows the expression `..` (without either endpoint) in general, can be
used in slicing syntax `&expr[..]` where we previously wrote `&expr[]`.
The old syntax &expr[] is not yet removed or warned for.

Update tests to change all `&expr[]` to `&expr[..]` to make sure pretty printing
passes.

Currently, if a `#![staged_api]` crate contains an exported item without a stability marker (or inherited stability),
the item is useless.
This change introduces a check to ensure that all exported items have a defined stability.
it also introduces the `unmarked_api` feature, which lets users import unmarked features. While this PR should in theory forbid these from existing,
in practice we can't be so sure; so this lets users bypass this check instead of having to wait for the library and/or compiler to be fixed (since otherwise this is a hard error).

This *almost* completes the job for #16440. The idea is that even if we do not know whether some closure type `C` implements `Fn` or `FnMut` (etc), we still know its argument and return types. So if we see an obligation `C : Fn(_0)`, we can unify `_0` with those argument types while still considering the obligation ambiguous and unsatisfied. This helps to make a lot of progress with type inference even before closure kind inference is done.
As part of this PR, the explicit `:` syntax is removed from the AST and completely ignored. We still infer the closure kind based on the expected type if that is available. There are several reasons for this. First, deciding the closure kind earlier is always better, as it allows us to make more progress. Second, this retains a (admittedly obscure) way for users to manually specify the closure kind, which is useful for writing tests if nothing else. Finally, there are still some cases where inference can fail, so it may be useful to have this manual override. (The expectation is that we will eventually revisit an explicit syntax for specifying the closure kind, but it will not be `:` and may be some sort of generalization of the `||` syntax to handle other traits as well.)
This commit does not *quite* fix #16640 because a snapshot is still needed to enable the obsolete syntax errors for explicit `&mut:` and friends.

Use the crates.io crate `rand` (version 0.1 should be a drop in
replacement for `std::rand`) and `rand_macros` (`#[derive_Rand]` should
be a drop-in replacement).

As part of [RFC 474](https://github.com/rust-lang/rfcs/pull/474), this
commit renames `std::path` to `std::old_path`, leaving the existing path
API in place to ease migration to the new one. Updating should be as
simple as adjusting imports, and the prelude still maps to the old path
APIs for now.

explicit annotation, leading to "extra `mut` declaration" lint errors.
|
|
upgrade the inference based on expected type so that it is able to
infer the fn kind in isolation even if the full signature is not
available (and we could perhaps do better still in some cases, such as
extracting just the types of the arguments but not the return value).

Now that associated types are fully implemented the iterator adaptors only need
type parameters which are associated with actual storage. All other type
parameters can either be derived from these (e.g. they are an associated type)
or can be bare on the `impl` block itself.
This is a breaking change due to the removal of type parameters on these
iterator adaptors, but code can fairly easily migrate by just deleting the
relevant type parameters for each adaptor. Other behavior should not be
affected.
Closes #21839

For "symmetric" binary operators, meaning the types of two sides must be
equal, if the type of LHS doesn't know yet but RHS does, use that as an
hint to infer LHS' type.

Hi.
Here a commit in order to add OpenBSD support to rust.
- tests status:
run-pass: test result: ok. 1879 passed; 0 failed; 24 ignored; 0 measured
run-fail: test result: ok. 81 passed; 0 failed; 5 ignored; 0 measured
compile-fail: test result: ok. 1634 passed; 0 failed; 22 ignored; 0 measured
run-pass-fulldeps: test result: ok. 22 passed; 0 failed; 1 ignored; 0 measured
compile-fail-fulldeps: test result: ok. 13 passed; 0 failed; 0 ignored; 0 measured
- The current implementation of load_self function (src/libstd/sys/unix/os.rs) isn't optimal as under OpenBSD I haven't found a reliable method to get the filename of a running process. The current implementation is enought for bootstrapping purpose.
- I have disable `run-pass/tcp-stress.rs` test under openbsd. When run manually, the test pass, but when run under `compiletest`, it timeout and echo continuoulsy `Too many open files`.
- For building with jemalloc, a more recent version of jemalloc would be mandatory. See https://github.com/jemalloc/jemalloc/pull/188 for more details.
