Constructing an Rc/Arc is unsafe even if the wrapped `T` is never dereferenced.
Future-proof these types in case rustc reorders the inner fields. As per discussion in PR rust-lang#68099.
…tch_single_binding)
As discussed in rust-lang#67939, this allows turning Option<ThreadId> into Option<NonZeroU64> which can then be stored inside an AtomicU64.
…tely (clippy::let_and_return)
…albertodt Amend Rc/Arc::from_raw() docs regarding unsafety [This](https://stackoverflow.com/questions/59671647/is-it-safe-to-clone-a-type-erased-arc-via-raw-pointer) question on SO boils down to "is it safe to `::from_raw()` a `Rc<T>`/`Arc<T>` using a dummy `T` even if `T` is never dereferenced via the new `Rc`/`Arc`?". It almost never is. This PR amends the docs of `from_raw()` regarding this point.
…trochenkov parse/lexer: support `StringReader::retokenize` called on external files. This ~~should theoretically~~ fixes rust-lang#69933, ~~but I'm not sure what the best way to test it is~~. **EDIT**: see rust-lang#69933 (comment). r? @petrochenkov cc @Xanewok @staktrace
…trochenkov parser: recover on `for<'a> |...| body` closures When encountering `for` and `<` is 1 token ahead, interpret this as an explicitly quantified generic closure and recover, rather than attempting to parse a `for` loop. This provides both improved diagnostics as well as an insurance policy for the ability to use this as the syntax for generic closures in the future. As requested by r? @eddyb
fix type of const params in associated types. fixes rust-lang#66906 fixes rust-lang#70167 r? @eddyb
more clippy fixes * remove unused unit values (clippy::unused_unit) * make some let-if-bindings more idiomatic (clippy::useless_let_if_seq) * clarify when we pass () to functions (clippy::unit_arg) * don't redundantly repeat field names (clippy::redundant_field_names) * remove redundant returns (clippy::needless_return) * use let instead of match for matches with single bindings (clippy::match_single_binding) * don't convert results to options just for matching (clippy::if_let_some_result)
Return NonZeroU64 from ThreadId::as_u64. As discussed in rust-lang#67939, this allows turning Option<ThreadId> into Option<NonZeroU64> which can then be stored inside an AtomicU64.
Remove wrong entry from RELEASES.md resolves rust-lang#70247
Remove another wrong entry from RELEASES.md The entry is under 1.11.0, but the feature is only available since 1.12.0 (for which an identical entry exists). 
couple more clippy fixes (let_and_return, if_same_then_else) * summarize if-else-code with identical blocks (clippy::if_same_then_else) * don't create variable bindings just to return the bound value immediately (clippy::let_and_return)
proc_macro_harness: Use item header spans for errors Addresses rust-lang#70233 (comment).
