}

A trait for the minimal common functionality of a vale array

Required Associated Types

type Element

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 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

Object Safety

This trait is not object safe.
