Implementations

impl Object

pub fn new() -> Object

Makes a new empty Object.

pub fn clear(&mut self)

Clears the map, removing all values.

pub fn get<Q>(&self, key: &Q) -> Option<&Value> where
    Q: Ord + Eq + Hash + ?Sized,
    KString: Borrow<Q>, 

Returns a reference to the value corresponding to the key.

The key may be any borrowed form of the map’s key type, but the ordering on the borrowed form must match the ordering on the key type.

pub fn contains_key<Q>(&self, key: &Q) -> bool where
    Q: Ord + Eq + Hash + ?Sized,
    KString: Borrow<Q>, 

Returns true if the map contains a value for the specified key.

The key may be any borrowed form of the map’s key type, but the ordering on the borrowed form must match the ordering on the key type.

pub fn get_mut<Q>(&mut self, key: &Q) -> Option<&mut Value> where
    Q: Ord + Eq + Hash + ?Sized,
    KString: Borrow<Q>, 

Returns a mutable reference to the value corresponding to the key.

The key may be any borrowed form of the map’s key type, but the ordering on the borrowed form must match the ordering on the key type.

pub fn insert(&mut self, k: KString, v: Value) -> Option<Value>

Inserts a key-value pair into the map.

If the map did not have this key present, None is returned.

If the map did have this key present, the value is updated, and the old value is returned.

pub fn remove<Q>(&mut self, key: &Q) -> Option<Value> where
    Q: Ord + Eq + Hash + ?Sized,
    KString: Borrow<Q>, 

Removes a key from the map, returning the value at the key if the key was previously in the map.

The key may be any borrowed form of the map’s key type, but the ordering on the borrowed form must match the ordering on the key type.

    S: Into<KString>, 

Gets the given key’s corresponding entry in the map for in-place manipulation.
