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

Returns an iterator over [ListItem] views into this list.

Trait Implementations

impl<T: Clone + Serialize + DeserializeOwned + Ord + PartialEq + Clone + Debug + 'static, V: Clone + StateMachine> Clone for Map<T, V>

fn clone(&self) -> Map<T, V>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug + Serialize + DeserializeOwned + Ord + PartialEq + Clone + Debug + 'static, V: Debug + StateMachine> Debug for Map<T, V>

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

Formats the value using the given formatter.

impl<T: Default + Serialize + DeserializeOwned + Ord + PartialEq + Clone + Debug + 'static, V: Default + StateMachine> Default for Map<T, V>

fn default() -> Map<T, V>

Returns the “default value” for a type.

impl<'de, T: Serialize + DeserializeOwned + Ord + PartialEq + Clone + Debug + 'static, V: StateMachine> Deserialize<'de> for Map<T, V>

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T: Serialize + DeserializeOwned + Ord + PartialEq + Clone + Debug + 'static, V: StateMachine> Serialize for Map<T, V>

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

Serialize this value into the given Serde serializer.

impl<T: Serialize + DeserializeOwned + Ord + PartialEq + Clone + Debug + 'static, V: StateMachine + PartialEq> StateMachine for Map<T, V>

type Transition = MapTransition<T, V>

The StateMachine::Transition type associates another type with this state machine as its transitions.

type Conflict = NeverConflict

fn apply(&self, transition: &Self::Transition) -> Result<Self, Self::Conflict>

Update the state machine according to the given [Transition]. This method must be deterministic: calling it on a clone of the state with a clone of the [Transition] must result in the same state, even at a different time and on a different machine. This is the requirement that allows Aper to keep the state in sync across multiple machines.
