2022-01-05ast: Always keep a `NodeId` in `ast::Crate`Vadim Petrochenkov-3/+7
This makes it more uniform with other expanded nodes
2022-01-01Auto merge of #92294 - Kobzol:rustdoc-meta-kind, r=GuillaumeGomezbors-4/+25
Add Attribute::meta_kind The `AttrItem::meta` function is being called on a lot of places, however almost always the caller is only interested in the `kind` of the result `MetaItem`. Before, the `path` had to be cloned in order to get the kind, now it does not have to be. There is a larger related "problem". In a lot of places, something wants to know contents of attributes. This is accessed through `Attribute::meta_item_list`, which calls `AttrItem::meta` (now `AttrItem::meta_kind`), among other methods. When this function is called, the meta item list has to be recreated from scratch. Everytime something asks a simple question (like is this item/list of attributes `#[doc(hidden)]`?), the tokens of the attribute(s) are cloned, parsed and the results are allocated on the heap. That seems really unnecessary. What would be the best way to cache this? Turn `meta_item_list` into a query perhaps? Related PR: https://github.com/rust-lang/rust/pull/92227 r? rust-lang/rustdoc

ast: Avoid aborts on fatal errors thrown from mutable AST visitor Set the node to some dummy value and rethrow the error instead. When using the old aborting `visit_clobber` in `InvocationCollector::visit_crate` the next tests abort due to fatal errors: ``` ui\modules\path-invalid-form.rs ui\modules\path-macro.rs ui\modules\path-no-file-name.rs ui\parser\issues\issue-5806.rs ui\parser\mod_file_with_path_attr.rs ``` Follow up to https://github.com/rust-lang/rust/pull/91313.

2021-12-19Auto merge of #91957 - nnethercote:rm-SymbolStr, r=oli-obkbors-2/+2
Remove `SymbolStr` This was originally proposed in https://github.com/rust-lang/rust/pull/74554#discussion_r466203544. As well as removing the icky `SymbolStr` type, it allows the removal of a lot of `&` and `*` occurrences. Best reviewed one commit at a time. r? `@oli-obk`

Fix bug with `#[doc]` string single-character last lines Fixes #90618. This is because `.iter().all(|c| c == '*')` returns `true` if there is no character checked. And in case the last line has only one character, it simply returns `true`, making the last line behind removed.
2021-11-07ast: Fix naming conventions in AST structuresVadim Petrochenkov-64/+134
TraitKind -> Trait TyAliasKind -> TyAlias ImplKind -> Impl FnKind -> Fn All `*Kind`s in AST are supposed to be enums. Tuple structs are converted to braced structs for the types above, and fields are reordered in syntactic order. Also, mutable AST visitor now correctly visit spans in defaultness, unsafety, impl polarity and constness.

rustc_ast: Turn `MutVisitor::token_visiting_enabled` into a constant It's a visitor property rather than something that needs to be determined at runtime

rustc_span: `Ident::invalid` -> `Ident::empty` The equivalent for `Symbol`s was renamed some time ago (`kw::Invalid` -> `kw::Empty`), and it makes sense to do the same thing for `Ident`s as well.

This reverts commit 059b68dd677808e14e560802d235ad40beeba71e. Note that this was manually adjusted to retain some of the refactoring introduced by commit 059b68dd677808e14e560802d235ad40beeba71e, so that it could likewise retain the correction introduced in commit 5b4bc05fa57be19bb5962f4b7c0f165e194e3151
