Fix confusing error message for comma typo in multiline statement Fixes rust-lang#72253. Expands on the issue with a colon typo check. r? @estebank cc @ehuss
Resolve UB in Arc/Weak interaction (2) Use raw pointers to avoid making any assertions about the data field. Follow up from rust-lang#72479, see that PR for more detail on the motivation. @RalfJung I was able to avoid a lot of the changes to `Weak`, by making a helper type (`WeakInner`) - because of auto-deref and because the fields have the same name, the rest of the code continues to compile.
…=nikomatsakis Add test for old compiler ICE when using `Borrow` The original issue was caused by implementing `Borrow` on a local type and using the tokio-reactor crate which had this impl: https://github.com/tokio-rs/tokio/blob/tokio-0.1.4/tokio-reactor/src/poll_evented.rs#L547-L577 This causes an ICE on Rust 1.27.0: ```console $ RUSTUP_TOOLCHAIN=1.27.0 rustc src/test/ui/issues/issue-50687-ice-on-borrow.rs error: internal compiler error: librustc/traits/structural_impls.rs:180: impossible case reached thread 'main' panicked at 'Box<Any>', librustc_errors/lib.rs:554:9 note: Run with `RUST_BACKTRACE=1` for a backtrace. error: aborting due to previous error note: the compiler unexpectedly panicked. this is a bug. note: we would appreciate a bug report: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports note: rustc 1.27.0 (3eda71b 2018-06-19) running on x86_64-apple-darwin ``` Closes rust-lang#50687

…changes, r=Dylan-DPC Remove font-display settings Since for the moment, the result isn't as expected since rust-lang#72092 when not using docs locally, let's revert them. r? @Dylan-DPC
…olnay Add remark regarding DoubleEndedIterator While reviewing rust-itertools/itertools@14293bd#diff-2c16d2ada06ad2fd1fc754679646d471, I realized that a `DoubleEndedIterator` may yield different elements depending on whether it is traversed forwards or backwards. (Not only the *order*, but possibly also the yielded values.) I found this remarkable, but could not find anything in the current docs, so I thought it may be worth mentioning this explicitly. Unfortunately, I could not test these changes locally (`rustdoc` complains about `unresolved import`). Sorry if this causes headache. If I should change something, please let me know. If it seems too trivial, feel free to just close this PR.
