#[repr(C)]pub struct RawHandle<T> {
pub ptr: *const T,
pub _phantom_0: PhantomData<UnsafeCell<T>>,
}
Expand description
Reference to a T that has been rooted elsewhere. This is most useful as a parameter type, which guarantees that the T lvalue is properly rooted. See “Move GC Stack Rooting” above.
If you want to add additional methods to Handle for a specific
specialization, define a HandleOperations
