2020-01-20Revert "Add a `constness` field to `ast::TraitRef`"Dylan MacKenzie-2/+1
This reverts commit fd4a6a12136c5b5d6bce4081e95890df1fd1febd.
2020-01-19Add `constness` field to `ast::ItemKind::Impl`Dylan MacKenzie-0/+1
2020-01-17Use named fields for `ast::ItemKind::Impl`Dylan MacKenzie-3/+11
2020-01-10Introduce `#![feature(half_open_range_patterns)]`.Mazdak Farrokhzad-2/+2
This feature adds `X..`, `..X`, and `..=X` patterns.
2020-01-09Add a `constness` field to `ast::TraitRef`Dylan MacKenzie-1/+2
This is used for both the `?const` syntax in bounds as well as the `impl const Trait` syntax. I also considered handling these separately by adding a variant of `TraitBoundModifier` and a field to `ItemKind::Impl`, but this approach was less intrusive.

2019-11-22Rollup merge of #66183 - Centril:empty-vis-trait-decl, r=petrochenkovMazdak Farrokhzad-22/+24
*Syntactically* permit visibilities on trait items & enum variants Fixes #65041 Suppose we have `$vis trait_item` or `$vis enum_variant` and `$vis` is a `:vis` macro fragment. Before this PR, this would fail to parse. This is now instead allowed as per language team consensus in https://github.com/rust-lang/rust/issues/65041#issuecomment-538105286. (See added tests for elaboration.) Moreover, we now also permit visibility modifiers on trait items & enum variants *syntactically* but reject them with semantic checks (in `ast_validation`): ```rust #[cfg(FALSE)] trait Foo { pub fn bar(); } // OK #[cfg(FALSE)] enum E { pub U } // OK ```

2019-11-06Make doc comments cheaper with `AttrKind`.Nicholas Nethercote-4/+8
`AttrKind` is a new type with two variants, `Normal` and `DocComment`. It's a big performance win (over 10% in some cases) because `DocComment` lets doc comments (which are common) be represented very cheaply. `Attribute` gets some new helper methods to ease the transition: - `has_name()`: check if the attribute name matches a single `Symbol`; for `DocComment` variants it succeeds if the symbol is `sym::doc`. - `is_doc_comment()`: check if it has a `DocComment` kind. - `{get,unwrap}_normal_item()`: extract the item from a `Normal` variant; panic otherwise. Fixes #60935.
2019-10-14Remove the `Option` in `TokenStream`.Nicholas Nethercote-4/+2
It means an allocation is required to create an empty `TokenStream`, but all other operations are simpler and marginally faster due to not having to check for `None`. Overall it simplifies the code for a negligible performance effect. The commit also removes `TokenStream::empty` by implementing `Default`, which is now possible.
