pub struct VariantLayout {
pub field_offsets: Vector<FieldId, u64>,
}
Expand description
Simplified layout of a single variant.
Maps fields to their offset within the layout.
Fields§
§field_offsets: Vector<FieldId, u64>
The offset of each field. None
if it is not knowable at this point, either because of
generics or dynamically-sized types.
