Enum List 

pub enum List<'parent, T> {
    Cons(&'parent List<'parent, T>, T),
    Nil,
}

A stack or arena-allocable append-only linked list.

Variants

Cons(&'parent List<'parent, T>, T)

A list with one more element than its parent

Nil

The base case: an empty list

Implementations

impl<'parent, T> List<'parent, T>

pub fn new(value: T) -> List<'static, T>

Creates a new single-element List

pub fn enter<'a>(&'a self, value: T) -> List<'a, T>

where T: 'a,

Creates a List with one more element than self

pub fn value(&self) -> Option<&T>

Gets the value contained in this List (the car)

pub fn parent(&self) -> Option<&List<'parent, T>>

Gets the parent element of this List (the cdr)

pub fn iter(&self) -> ListIter<'_, T>

Gets an Iterator over the elements of this List.

Elements are yielded in reverse insertion order (most to least recent)

pub fn get_reverse(&self) -> Vec<&T>
