In this example of odin code i implemented data structures with iterator pattern using slices odin execpt linked-list. In odin slices are like a struct involving a capacity,length and a raw pointer [^]T so due to the issue of alignment the example is quite broken but i would suggest using raw pointer for implementing any kind of data structure with working iterator pattern do not for now do not use odins buildin slices although they are very powerfull but in a very low level stuff such as vtable and etc use raw pointer.

This is a simple experiment in implementing the iterator pattern in the Odin programming language. The iterator pattern provides a way to sequentially access elements of a collection without exposing the underlying details of its representation.

The Iterator struct defines an iterator with a next function to iterate over a collection. It holds a pointer to the current data, the next function, and the size of the collection.

The List struct represents a basic linked list. It embeds an iterator to enable iteration over its elements.

The Vec struct represents a dynamic array (vector) and also embeds an iterator for iteration over its elements.

The init procedure initializes a linked list with a given value and sets up the iterator functions.

The Vec_init procedure initializes a dynamic array with a default capacity. It also sets up the iterator functions for the dynamic array.

In the main procedure, a dynamic array of integers is created using Vec_init, and some values are assigned. The iterator is then used to print selected elements from the array. Memory
