A JSON Object

Associated Types

type Key[src]

type Element[src]

The values in the object

Required methods

#[must_use]
fn get<Q: ?Sized>(&self, k: &Q) -> Option<&Self::Element> where
    Self::Key: Borrow<Q> + Hash + Eq,
    Q: Hash + Eq + Ord, [src]

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.

#[must_use]
fn get_mut<Q: ?Sized>(&mut self, k: &Q) -> Option<&mut Self::Element> where
    Self::Key: Borrow<Q> + Hash + Eq,
    Q: Hash + Eq + Ord, [src]

Gets the value of a key as a mutable reference.

#[must_use]
fn insert<K, V>(&mut self, k: K, v: V) -> Option<Self::Element> where
    K: Into<Self::Key>,
    V: Into<Self::Element>,
    Self::Key: Hash + Eq, [src]

Inserts a value

#[must_use]
fn remove<Q: ?Sized>(&mut self, k: &Q) -> Option<Self::Element> where
    Self::Key: Borrow<Q>,
    Q: Hash + Eq + Ord, [src]

Removes a value from the object

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

Iterates over the key value paris

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

Iterates over the keys

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

Iterates over the values
