Enum rustc_type_ir::ty_kind::DynKind
source · pub enum DynKind {
Dyn,
DynStar,
}
Expand description
Specifies how a trait object is represented.
Variants§
Dyn
An unsized dyn Trait
object
DynStar
A sized dyn* Trait
object
These objects are represented as a (data, vtable)
pair where data
is a value of some
ptr-sized and ptr-aligned dynamically determined type T
and vtable
is a pointer to the
vtable of impl T for Trait
. This allows a dyn*
object to be treated agnostically with
respect to whether it points to a Box<T>
, Rc<T>
, etc.
