Implementations§

Source§

impl Map<String, Value>

Source

pub fn new() -> Map<String, Value>

Makes a new empty Map.

Source

pub fn with_capacity(capacity: usize) -> Map<String, Value>

Makes a new empty Map with the given initial capacity.

Source

pub fn clear(&mut self)

Clears the map, removing all values.

Source

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

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.

Source

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

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.

Source

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

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.

Source

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

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.

Source

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.

Source

pub fn shift_insert( &mut self, index: usize, k: String, v: Value, ) -> Option<Value>

Insert a key-value pair in the map at the given index.

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

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

Source

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

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.

If serde_json’s “preserve_order” is enabled, .remove(key) is equivalent to .swap_remove(key), replacing this entry’s position with the last element. If you need to preserve the relative order of the keys in the map, use .shift_remove(key) instead.

Source

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

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.

If serde_json’s “preserve_order” is enabled, .remove_entry(key) is equivalent to .swap_remove_entry(key), replacing this entry’s position with the last element. If you need to preserve the relative order of the keys in the map, use .shift_remove_entry(key) instead.

Source

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

Removes and returns the value corresponding to the key from the map.

Like Vec::swap_remove, the entry is removed by swapping it with the last element of the map and popping it off. This perturbs the position of what used to be the last element!

Source

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

Remove and return the key-value pair.

Like Vec::swap_remove, the entry is removed by swapping it with the last element of the map and popping it off. This perturbs the position of what used to be the last element!

Source

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

Removes and returns the value corresponding to the key from the map.

Like Vec::remove, the entry is removed by shifting all of the elements that follow it, preserving their relative order. This perturbs the index of all of those elements!

Source

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

Remove and return the key-value pair.

Like Vec::remove, the entry is removed by shifting all of the elements that follow it, preserving their relative order. This perturbs the index of all of those elements!

Source

pub fn append(&mut self, other: &mut Map<String, Value>)

Moves all elements from other into self, leaving other empty.

Source

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.

Source

pub fn len(&self) -> usize

Returns the number of elements in the map.

Source

pub fn is_empty(&self) -> bool

Returns true if the map contains no elements.

Source

pub fn iter(&self) -> Iter<'_>

Gets an iterator over the entries of the map.

Source

pub fn iter_mut(&mut self) -> IterMut<'_>

Gets a mutable iterator over the entries of the map.

Source

pub fn keys(&self) -> Keys<'_>

Gets an iterator over the keys of the map.

Source

pub fn values(&self) -> Values<'_>

Gets an iterator over the values of the map.

Source

pub fn values_mut(&mut self) -> ValuesMut<'_>

Gets an iterator over mutable values of the map.

Source

pub fn into_values(self) -> IntoValues

Gets an iterator over the values of the map.

Source

pub fn retain<F>(&mut self, f: F)
where F: FnMut(&String, &mut Value) -> bool,

Retains only the elements specified by the predicate.

In other words, remove all pairs (k, v) such that f(&k, &mut v) returns false.

Source

pub fn sort_keys(&mut self)

Sorts this map’s entries in-place using str’s usual ordering.

If serde_json’s “preserve_order” feature is not enabled, this method does no work because all JSON maps are always kept in a sorted state.

If serde_json’s “preserve_order” feature is enabled, this method destroys the original source order or insertion order of this map in favor of an alphanumerical order that matches how a BTreeMap with the same contents would be ordered. This takes O(n log n + c) time where n is the length of the map and c is the capacity.

Other maps nested within the values of this map are not sorted. If you need the entire data structure to be sorted at all levels, you must also call map.values_mut().for_each(Value::sort_all_objects).
