Prelude to include needed traits A trait for the minimal common functionality of a vale object

Required Associated Types

type Key: ?Sized

The key in the objects

type Element

The values in the object

Required Methods

fn get<Q>(&self, k: &Q) -> Option<&Self::Element>

where Self::Key: Borrow<Q> + Hash + Eq, Q: Hash + Eq + Ord + ?Sized,

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

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

Iterates over the key value paris

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

Iterates over the keys

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

Iterates over the values

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.
