2025-08-14Improved `Target` typeJonathan Brouwer-1/+1
- Added a few more variants which are needed for various attributes - Previously a trait method with default block had the same target representation as a method in a `impl trait for` block, this has been changed (See `MethodKind`) - Added `plural_name` for more precision on the form of the name

2025-04-01Move `ast::Item::ident` into `ast::ItemKind`.Nicholas Nethercote-7/+7
`ast::Item` has an `ident` field. - It's always non-empty for these item kinds: `ExternCrate`, `Static`, `Const`, `Fn`, `Mod`, `TyAlias`, `Enum`, `Struct`, `Union`, `Trait`, `TraitAlias`, `MacroDef`, `Delegation`. - It's always empty for these item kinds: `Use`, `ForeignMod`, `GlobalAsm`, `Impl`, `MacCall`, `DelegationMac`. There is a similar story for `AssocItemKind` and `ForeignItemKind`. Some sites that handle items check for an empty ident, some don't. This is a very C-like way of doing things, but this is Rust, we have sum types, we can do this properly and never forget to check for the exceptional case and never YOLO possibly empty identifiers (or possibly dummy spans) around and hope that things will work out. The commit is large but it's mostly obvious plumbing work. Some notable things. - `ast::Item` got 8 bytes bigger. This could be avoided by boxing the fields within some of the `ast::ItemKind` variants (specifically: `Struct`, `Union`, `Enum`). I might do that in a follow-up; this commit is big enough already. - For the visitors: `FnKind` no longer needs an `ident` field because the `Fn` within how has one. - In the parser, the `ItemInfo` typedef is no longer needed. It was used in various places to return an `Ident` alongside an `ItemKind`, but now the `Ident` (if present) is within the `ItemKind`. - In a few places I renamed identifier variables called `name` (or `foo_name`) as `ident` (or `foo_ident`), to better match the type, and because `name` is normally used for `Symbol`s. It's confusing to see something like `foo_name.name`.

For the the symbols that might not be present, instead of `kw::Empty`.
2024-12-18Re-export more `rustc_span::symbol` things from `rustc_span`.Nicholas Nethercote-5/+4
`rustc_span::symbol` defines some things that are re-exported from `rustc_span`, such as `Symbol` and `sym`. But it doesn't re-export some closely related things such as `Ident` and `kw`. So you can do `use rustc_span::{Symbol, sym}` but you have to do `use rustc_span::symbol::{Ident, kw}`, which is inconsistent for no good reason. This commit re-exports `Ident`, `kw`, and `MacroRulesNormalizedIdent`, and changes many `rustc_span::symbol::` qualifiers in `compiler/` to `rustc_span::`. This is a 200+ net line of code reduction, mostly because many files with two `use rustc_span` items can be reduced to one.

2022-10-29Rename some `OwnerId` fields.Nicholas Nethercote-2/+2
spastorino noticed some silly expressions like `item_id.def_id.def_id`. This commit renames several `def_id: OwnerId` fields as `owner_id`, so those expressions become `item_id.owner_id.def_id`. `item_id.owner_id.local_def_id` would be even clearer, but the use of `def_id` for values of type `LocalDefId` is *very* widespread, so I left that alone.

2021-08-25Auto merge of #87875 - asquared31415:generic-lang-items, r=cjgillotbors-87/+35
Improve detection of generics on lang items Adds detection for the required generics for all lang items. Many lang items require an exact or minimum amount of generic arguments and if they don't exist, the compiler will ICE. This does not add any additional validation about bounds on generics or any other lang item restrictions. Fixes one of the ICEs in #87573 cc `@FabianWolff`
