Struct NeoMap 

pub struct NeoMap<K, V> { /* private fields */ }

Neo N3 Map type

Implementations

impl<K, V> NeoMap<K, V>

pub fn new() -> NeoMap<K, V>

pub fn insert(&mut self, key: K, value: V) -> Option<V>

where K: PartialEq,

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

where K: PartialEq,

Gets a reference to the value associated with the given key.

Performance

This operation is O(n) as it performs a linear search. Consider using a HashMap for O(1) lookups if performance is critical.

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

where K: PartialEq,

Gets a mutable reference to the value associated with the given key.

Performance

This operation is O(n) as it performs a linear search.

pub fn remove(&mut self, key: &K) -> Option<V>

where K: PartialEq,

Removes the key-value pair associated with the given key.

Performance

This operation is O(n) due to the element removal.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn iter(&self) -> impl Iterator<Item = (&K, &V)>

pub fn keys(&self) -> impl Iterator<Item = &K>

Returns an iterator over the keys of the map

pub fn values(&self) -> impl Iterator<Item = &V>

Returns an iterator over the values of the map

Trait Implementations

impl<K, V> Clone for NeoMap<K, V>

where K: Clone, V: Clone,

fn clone(&self) -> NeoMap<K, V>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<K, V> Debug for NeoMap<K, V>

where K: Debug, V: Debug,

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

Formats the value using the given formatter.

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

fn default() -> NeoMap<K, V>

Returns the “default value” for a type.

impl<'de, K, V> Deserialize<'de> for NeoMap<K, V>

where K: Deserialize<'de> + Eq, V: Deserialize<'de>,

fn deserialize<__D>( __deserializer: __D, ) -> Result<NeoMap<K, V>, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<NeoMap<NeoValue, NeoValue>> for NeoValue

fn from(value: NeoMap<NeoValue, NeoValue>) -> NeoValue

Converts to this type from the input type.

impl<K, V> PartialEq for NeoMap<K, V>

where K: PartialEq, V: PartialEq,

fn eq(&self, other: &NeoMap<K, V>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<K, V> Serialize for NeoMap<K, V>

where K: Serialize + Eq, V: Serialize,

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<K, V> Eq for NeoMap<K, V>

where K: Eq, V: Eq,

impl<K, V> StructuralPartialEq for NeoMap<K, V>
