pub unsafe trait NoDrop { }Expand description
A marker trait indicating it’s OK to not drop an instance of that type.
The MemoryAllocator allocates memory for objects and return a pointer or reference to the allocated memory.
While doing so, it does NOT maintain the type or destructors of allocated objects, and does not call their
destructor (if exit). This trait marks types that can safely be not dropped.
§Safety
When implementing this trait for a type, the user must ensure the type does not implement the Drop trait.
