Fields

llval: V

A pointer to the contents of the place.

llextra: Option<V>

This place’s extra data if it is unsized, or None if null.

layout: TyAndLayout<'tcx>

The monomorphized type of this place, including variant information.

align: Align

The alignment we know for this place.

Trait Implementations

impl<'tcx, V: Clone> Clone for PlaceRef<'tcx, V>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'tcx, V: Debug> Debug for PlaceRef<'tcx, V>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
