Struct TransItemSource 

pub struct TransItemSource<'tcx> {
    pub item: RustcItem<'tcx>,
    pub kind: TransItemSourceKind,
}

The id of an untranslated item. Note that a given DefId may show up as multiple different item sources, e.g. a constant will have both a Global version (for the constant itself) and a FunDecl one (for its initializer function).

Fields

item: RustcItem<'tcx>

kind: TransItemSourceKind

Implementations

impl<'tcx> TransItemSource<'tcx>

pub fn new(item: RustcItem<'tcx>, kind: TransItemSourceKind) -> Self

pub fn from_item( item: &ItemRef<'tcx>, kind: TransItemSourceKind, monomorphize: bool, ) -> Self

Refers to the given item. Depending on monomorphize, this chooses between the monomorphic and polymorphic versions of the item.

pub fn polymorphic(def_id: &DefId, kind: TransItemSourceKind) -> Self

Refers to the polymorphic version of this item.

pub fn monomorphic(item: &ItemRef<'tcx>, kind: TransItemSourceKind) -> Self

Refers to the monomorphic version of this item.

pub fn monomorphic_trait(def_id: &DefId, kind: TransItemSourceKind) -> Self

Refers to the monomorphic trait (or vtable). See the docs of RustcItem::MonoTrait for details.

pub fn def_id(&self) -> &DefId

pub(crate) fn with_kind(&self, kind: TransItemSourceKind) -> Self

Keep the same def_id but change the kind.

pub(crate) fn parent(&self) -> Option<Self>

For virtual items that have a parent (typically a method impl), return this parent. Does not attempt to generally compute the parent of an item. Used to compute names.

pub(crate) fn is_derived_item(&self) -> bool

Whether this item is the “main” item for this def_id or not (e.g. Destruct impl/methods are not the main item).
