struct ClashingExternDeclarations {
    seen_decls: FxHashMap<Symbol, OwnerId>,
}

Fields§

§seen_decls: FxHashMap<Symbol, OwnerId>

Map of function symbol name to the first-seen hir id for that symbol name.. If seen_decls contains an entry for key K, it means a symbol with name K has been seen by this lint and the symbol should be reported as a clashing declaration.

Implementations§

source§

impl ClashingExternDeclarations

source

pub(crate) fn new() -> Self

source

fn insert(&mut self, tcx: TyCtxt<'_>, fi: ForeignItemId) -> Option<OwnerId>

Insert a new foreign item into the seen set. If a symbol with the same name already exists for the item, return its HirId without updating the set.

source

fn check_foreign_item<'tcx>( &mut self, tcx: TyCtxt<'tcx>, this_fi: ForeignItemId )
