[−][src]Trait abi_stable::pointer_trait::CanTransmuteElement

pub unsafe trait CanTransmuteElement<T>: GetPointerKind {
    type TransmutedPtr: Deref<Target = T>;
}

Whether the pointer can be transmuted to have T as the referent type.

Safety for implementor

Implementors of this trait must ensure that:

  • The memory layout of this type is the same regardless of the type of the referent .

  • The pointer type is either !Drop(no drop glue either), or it uses a vtable to Drop the referent and deallocate the memory correctly.

Associated Types

The type of the pointer after it's element type has been changed.
