Enum UnsafeCellStrategy 

pub enum UnsafeCellStrategy {
    Sized {
        cells: List<(Size, Size)>,
    },
    Slice {
        element_cells: List<(Size, Size)>,
    },
    TraitObject,
    Tuple {
        head_cells: List<(Size, Size)>,
        tail_cells: GcCow<UnsafeCellStrategy>,
    },
}

Describes where in a potentially unsized type the UnsafeCell are. Separate from LayoutStrategy since we must be able to compute LayoutStrategy from a MiniRust Type, but that does not have enough information for an UnsafeCellStrategy. FIXME: maybe it should?

Variants

Sized

List of offsets and sizes of UnsafeCells.

Fields

cells: List<(Size, Size)>

Slice

Since the elements of a slice have the same type, we only keep track of the UnsafeCell’s of one element, we can then “repeat” this for the rest of the slice.

Fields

element_cells: List<(Size, Size)>

TraitObject

The bytes for UnsafeCell’s must be looked up in the VTable.

Tuple

A Tuple consists of a sized head an unsized tail.

Fields

head_cells: List<(Size, Size)>

tail_cells: GcCow<UnsafeCellStrategy>
