Struct rustc_hir::lang_items::LanguageItems [−][src]
All of the language items, defined or not. Defined lang items can come from the current crate or its dependencies.
Fields
items: Vec<Option<DefId>>Mappings from lang items to their possibly found DefIds.
The index corresponds to the order in LangItem.
missing: Vec<LangItem>Lang items that were not found during collection.
groups: [Vec<DefId>; 1]Mapping from LangItemGroup discriminants to all
DefIds of lang items in that group.
