Struct Dictionary

pub struct Dictionary<K, V>
where
    K: PartialEq,
{ /* private fields */ }

Data structure for storing key-value pairs, with partial key lookup feature.

Implementations

impl<K, V> Dictionary<K, V>

where K: PartialEq,

pub fn new() -> Self

Creates a new empty Dictionary.

pub fn is_empty(&self) -> bool

Checks whether this Dictionary is empty - contains no key-value pairs.

pub fn len(&self) -> usize

Returns the number of key-value pairs contained in this Dictionary.

pub fn insert<W>(&mut self, key: W, value: V)

where W: IntoIterator<Item = K>,

Inserts a key-value pair into the Dictionary.

pub fn get<W>(&self, key: W) -> Option<&V>

where W: IntoIterator<Item = K>,

Returns reference to the value paired with the given key. Returns None if there is no value stored with the given key.

pub fn get_mut<W>(&mut self, key: W) -> Option<&mut V>

where W: IntoIterator<Item = K>,

Returns mutable reference to the value paired with the given key. Returns None if there is no value stored with the given key.

pub fn lookup(&self) -> Lookup<'_, K, V>

Creates a Lookup into the Dictionary used for searching inside of the dictionary.

Trait Implementations

impl<K, V: Debug> Debug for Dictionary<K, V>

where K: PartialEq + Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<K, V> Default for Dictionary<K, V>

where K: PartialEq,

fn default() -> Self

Returns the “default value” for a type.

impl<KeyParts, K, V> FromIterator<(KeyParts, V)> for Dictionary<K, V>

where KeyParts: IntoIterator<Item = K>, K: PartialEq,

fn from_iter<I: IntoIterator<Item = (KeyParts, V)>>(iter: I) -> Self

Creates a value from an iterator.
