Struct LWWMap 

pub struct LWWMap<K: Clone + Eq + Hash + Serialize, V: Clone + Serialize> { /* private fields */ }

A map where the most recent write for each key wins.

Implementations

impl<K: Clone + Eq + Hash + Serialize + for<'de> Deserialize<'de>, V: Clone + Serialize + for<'de> Deserialize<'de>> LWWMap<K, V>

pub fn new() -> Self

Create a new LWW-Map.

pub fn set(&mut self, key: K, value: V, node_id: &NodeId)

Set a key-value pair.

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

Get a value by key.

pub fn remove(&mut self, key: &K)

Remove a key (by setting to a tombstone timestamp).

pub fn keys(&self) -> Vec<&K>

Get all keys.

pub fn len(&self) -> usize

Get the number of entries.

pub fn is_empty(&self) -> bool
