pub trait MapBackend<K: Clone + Eq + Hash, V: Clone>: Send + Sync {
    // Required methods
    fn size(&self) -> usize;
    fn has(&self, key: &K) -> bool;
    fn get(&self, key: &K) -> Option<V>;

Storage backend for crate::ReactiveMap.

Required Methods

fn size(&self) -> usize

fn has(&self, key: &K) -> bool

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

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

fn set_many(&mut self, entries: Vec<(K, V)>)

fn delete(&mut self, key: &K) -> bool

fn delete_many(&mut self, keys: &[K]) -> usize

fn clear(&mut self) -> usize

fn to_vec(&self) -> Vec<(K, V)>

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
