Enum rustc_typeck::check::cast::PointerKind[−][src]

enum PointerKind<'tcx> {
    Thin,
    Vtable(Option<DefId>),
    Length,
    OfProjection(&'tcx ProjectionTy<'tcx>),
    OfOpaque(DefId, SubstsRef<'tcx>),

Expand description

The kind of pointer and associated metadata (thin, length or vtable) - we only allow casts between fat pointers if their metadata have the same kind.

Variants

Thin
Expand description

No metadata attached, ie pointer to sized type or foreign type

Vtable(Option<DefId>)
Expand description

A trait object

Length
Expand description

Slice

OfProjection(&'tcx ProjectionTy<'tcx>)
Expand description

The unsize info of this projection

OfOpaque(DefId, SubstsRef<'tcx>)
Expand description

The unsize info of this opaque ty

OfParam(&'tcx ParamTy)
Expand description

The unsize info of this parameter
