Struct UniqueVec 

struct UniqueVec<T: Clone + Hash + Eq> {
    items: Vec<T>,
    index: HashMap<T, usize>,
}

An array of objects with the following properties:

• each item appears only once
• efficient insertion and lookup of indexes of existing items
• insertion order is maintained, indexes are stable across modification
• can do .as_bytes() for items that are IntoBytes + Immutable

Fields

items: Vec<T>

index: HashMap<T, usize>
