Functions guaranteed for any array object

Associated Types

type Element: Value

Elements of the array

Required methods

fn get<I>(&self, i: I) -> Option<&<I as SliceIndex<[Self::Element]>>::Output> where
    I: SliceIndex<[Self::Element]>, 

Gets a ref to a value based on n index, returns None if the current Value isn’t an Array or doesn’t contain the index it was asked for.

fn get_mut(&mut self, i: usize) -> Option<&mut Self::Element>

Gets a ref to a value based on n index, returns None if the current Value isn’t an Array or doesn’t contain the index it was asked for.

fn pop(&mut self) -> Option<Self::Element>

Returns the last element of the array or None

fn push(&mut self, e: Self::Element)

Appends e to the end of the Array

fn iter<'i>(&'i self) -> Box<dyn Iterator<Item = &Self::Element> + 'i>

Iterates over the values paris

fn len(&self) -> usize

Number of key/value pairs

Provided methods

fn is_empty(&self) -> bool

Returns if the array is empty
