Simple linked-list struct in Rust that doesn't work.

linked-list.rs

struct Node<T> {
  value: T,
  next: Option<~Node<T>>
}

struct LinkedList<T> {
  head: ~Node<T>,
  tail: ~Node<T>
}


impl<T> LinkedList<T> {

  fn new(item: T) -> LinkedList<T> {
    let node = ~Node { value: item, next: None };
    LinkedList { head: node, tail: node }
  }

}


fn main() {
  let n: LinkedList<~str> = LinkedList::new(~"hey there");
  
}
