Implementations
sourceimpl Map<String, Value>
impl Map<String, Value>
sourcepub fn with_capacity(capacity: usize) -> Map<String, Value>
pub fn with_capacity(capacity: usize) -> Map<String, Value>
Makes a new empty Map with the given initial capacity.
sourcepub fn get<Q>(&self, key: &Q) -> Option<&Value> where
Q: Ord + Eq + Hash + ?Sized,
String: Borrow<Q>,
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.
sourcepub fn contains_key<Q>(&self, key: &Q) -> bool where
Q: Ord + Eq + Hash + ?Sized,
String: Borrow<Q>,
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.
sourcepub fn get_mut<Q>(&mut self, key: &Q) -> Option<&mut Value> where
Q: Ord + Eq + Hash + ?Sized,
String: Borrow<Q>,
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.
sourcepub fn get_key_value<Q>(&self, key: &Q) -> Option<(&String, &Value)> where
Q: Ord + Eq + Hash + ?Sized,
String: Borrow<Q>,
pub fn get_key_value<Q>(&self, key: &Q) -> Option<(&String, &Value)> where
Q: Ord + Eq + Hash + ?Sized,
String: Borrow<Q>,
Returns the key-value pair matching the given 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.
sourcepub fn insert(&mut self, k: String, v: Value) -> Option<Value>
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.
sourcepub fn remove<Q>(&mut self, key: &Q) -> Option<Value> where
Q: Ord + Eq + Hash + ?Sized,
String: Borrow<Q>,
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.
sourcepub fn remove_entry<Q>(&mut self, key: &Q) -> Option<(String, Value)> where
Q: Ord + Eq + Hash + ?Sized,
String: Borrow<Q>,
pub fn remove_entry<Q>(&mut self, key: &Q) -> Option<(String, Value)> where
Q: Ord + Eq + Hash + ?Sized,
String: Borrow<Q>,
Removes a key from the map, returning the stored key and value 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.
sourcepub fn append(&mut self, other: &mut Map<String, Value>)
pub fn append(&mut self, other: &mut Map<String, Value>)
Moves all elements from other into Self, leaving other empty.
sourcepub fn entry<S>(&mut self, key: S) -> Entry<'_> where
S: Into<String>,
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 iter(&self) -> Iter<'_>ⓘNotable traits for Iter<'a>impl<'a> Iterator for Iter<'a> type Item = (&'a String, &'a Value);
