Struct rustc_lint::builtin::ClashingExternDeclarations
source · Fields
seen_decls: FxHashMap<Symbol, HirId>
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
sourceimpl ClashingExternDeclarations
impl ClashingExternDeclarations
pub(crate) fn new() -> Self
sourcefn insert(&mut self, tcx: TyCtxt<'_>, fi: &ForeignItem<'_>) -> Option<HirId>
fn insert(&mut self, tcx: TyCtxt<'_>, fi: &ForeignItem<'_>) -> Option<HirId>
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.
sourcefn name_of_extern_decl(tcx: TyCtxt<'_>, fi: &ForeignItem<'_>) -> SymbolName
fn name_of_extern_decl(tcx: TyCtxt<'_>, fi: &ForeignItem<'_>) -> SymbolName
Get the name of the symbol that’s linked against for a given extern declaration. That is, the name specified in a #[link_name = …] attribute if one was specified, else, just the symbol’s name.
sourcefn structurally_same_type<'tcx>(
cx: &LateContext<'tcx>,
a: Ty<'tcx>,
b: Ty<'tcx>,
ckind: CItemKind
) -> bool
fn structurally_same_type<'tcx>(
cx: &LateContext<'tcx>,
a: Ty<'tcx>,
b: Ty<'tcx>,
ckind: CItemKind
) -> bool
Checks whether two types are structurally the same enough that the declarations shouldn’t clash. We need this so we don’t emit a lint when two modules both declare an extern struct, with the same members (as the declarations shouldn’t clash).
