Struct Owned 

pub struct Owned<T: ?Sized> { /* private fields */ }

Marker type for owned pointers.

An Owned<T> wraps a NonNull<T> and indicates that the holder is responsible for freeing the underlying object at the end of its lifetime.

SAFETY

The Drop implementation will free the wrapped pointer using the appropriate xmlFree* function. The caller must ensure:

• The pointer was allocated by libxml2’s allocator
• No other code holds a mutable reference to the pointed-to data
• The pointer is not freed twice
