Enum dogs::data_structures::lazy_clonable::LazyClonableContent

pub enum LazyClonableContent<T: Clone> {
    Ref(Rc<T>),
    Computed(Rc<T>),
}

Implements a data-structure that allows to perform a lazy copy. At the beginning, it only stores a pointer towards the parent datastructure. When the lazy_get method is called for the first time, the datastructure is copied from the parent reference. For later calls, the lazyget method only returns the existing copy.

Variants

Ref

reference to the “parent” element

Computed

reference to “itself”
