Access to a value as an object

Required Associated Types

type Key: ?Sized

The type for Objects

type Target

The target for nested lookups

Required Methods

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

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 contains_key<Q>(&self, k: &Q) -> bool

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

Checks if a Value contains a given key. This will return flase if Value isn’t an object

Object Safety

This trait is not object safe.
