Trait State 

pub trait State {
    // Required methods
    fn get(&self, key: &Key) -> impl Future<Output = Option<Value>>;
    fn insert(&mut self, key: Key, value: Value) -> impl Future<Output = ()>;
    fn delete(&mut self, key: &Key) -> impl Future<Output = ()>;

    // Provided method
    fn apply(&mut self, changes: Vec<(Key, Status)>) -> impl Future<Output = ()> { ... }
}

Required Methods

fn get(&self, key: &Key) -> impl Future<Output = Option<Value>>

fn insert(&mut self, key: Key, value: Value) -> impl Future<Output = ()>

fn delete(&mut self, key: &Key) -> impl Future<Output = ()>

Provided Methods

fn apply(&mut self, changes: Vec<(Key, Status)>) -> impl Future<Output = ()>

Dyn Compatibility

This trait is not dyn compatible.

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