2020-03-26introduce `negative_impls` feature gate and documentNiko Matsakis-0/+1
They used to be covered by `optin_builtin_traits` but negative impls are now applicable to all traits, not just auto traits. This also adds docs in the unstable book for the current state of auto traits.

2020-03-11Add Display and Error impls for proc_macro::LexErrorKinsey Favre-1/+11
This should allow LexError to play much nicer with the `?` operator.
2020-01-10Remove unnecessary `const_fn` feature gatesDylan MacKenzie-1/+0
This flag opts out of the min-const-fn checks entirely, which is usually not what we want. The few cases where the flag is still necessary have been annotated.

2019-04-05Use for_each to extend collectionsJosh Stone-3/+1
This updates the `Extend` implementations to use `for_each` for many collections: `BinaryHeap`, `BTreeMap`, `BTreeSet`, `LinkedList`, `Path`, `TokenStream`, `VecDeque`, and `Wtf8Buf`. Folding with `for_each` enables better performance than a `for`-loop for some iterators, especially if they can just forward to internal iterators, like `Chain` and `FlatMap` do.
2019-03-27Auto merge of #55780 - ogoffart:span_source_text, r=petrochenkovbors-0/+12
Introduce proc_macro::Span::source_text A function to extract the actual source behind a Span. Background: I would like to use `syn` in a `build.rs` script to parse the rust code, and extract part of the source code. However, `syn` only gives access to proc_macro2::Span, and i would like to get the source code behind that. I opened an issue on proc_macro2 bug tracker for this feature https://github.com/alexcrichton/proc-macro2/issues/110 and @alexcrichton said the feature should first go upstream in proc_macro. So there it is! Since most of the Span API is unstable anyway, this is guarded by the same `proc_macro_span` feature as everything else.

2019-02-12Auto merge of #58341 - alexreg:cosmetic-2-doc-comments, r=steveklabnikbors-6/+6
Cosmetic improvements to doc comments This has been factored out from https://github.com/rust-lang/rust/pull/58036 to only include changes to documentation comments (throughout the rustc codebase). r? @steveklabnik Once you're happy with this, maybe we could get it through with r=1, so it doesn't constantly get invalidated? (I'm not sure this will be an issue, but just in case...) Anyway, thanks for your advice so far!

2018-09-02proc_macro::Group::span_open and span_closeDavid Tolnay-1/+42
Before this addition, every delimited group like (...) [...] {...} has only a single Span that covers the full source location from opening delimiter to closing delimiter. This makes it impossible for a procedural macro to trigger an error pointing to just the opening or closing delimiter. The Rust compiler does not seem to have the same limitation: mod m { type T = } error: expected type, found `}` --> src/main.rs:3:1 | 3 | } | ^ On that same input, a procedural macro would be forced to trigger the error on the last token inside the block, on the entire block, or on the next token after the block, none of which is really what you want for an error like above. This commit adds group.span_open() and group.span_close() which access the Span associated with just the opening delimiter and just the closing delimiter of the group. Relevant to Syn as we implement real error messages for when parsing fails in a procedural macro.
