Methods

impl Context

pub fn new() -> Self

pub fn from_json(v: Value) -> Self

pub fn set<V>(&mut self, k: &str, v: V) -> &mut Self where
    V: Serialize, 

pub fn with<V>(self, k: &str, v: V) -> Self where
    V: Serialize, 

pub fn pointer(&self, pointer: &str) -> Option<&Value>

pub fn to_value(&self) -> Value

pub fn as_value(&self) -> &Value

Methods from Deref<Target = Map<String, Value>>

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,
    String: 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,
    String: 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,
    String: 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: String, 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,
    String: 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.

pub fn entry<S>(&mut self, key: S) -> Entry where
    S: Into<String>, 

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

pub fn len(&self) -> usize

Returns the number of elements in the map.

pub fn is_empty(&self) -> bool

Returns true if the map contains no elements.

pub fn iter(&self) -> Iter

Gets an iterator over the entries of the map.

pub fn iter_mut(&mut self) -> IterMut

Gets a mutable iterator over the entries of the map.

pub fn keys(&self) -> Keys

Gets an iterator over the keys of the map.

pub fn values(&self) -> Values

Gets an iterator over the values of the map.

pub fn values_mut(&mut self) -> ValuesMut

Gets an iterator over mutable values of the map.
