Represents a TOML key/value type.

Implementations

impl Map<String, Value>

pub fn new() -> Self

Makes a new empty Map.

pub fn with_capacity(capacity: usize) -> Self

Makes a new empty Map with the given initial capacity.

pub fn clear(&mut self)

Clears the map, removing all values.

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

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

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

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. The key is not updated, though; this matters for types that can be == without being identical.

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

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.
