Trait AsyncMap

Source 
pub trait AsyncMap: Clone + Send {
    type Key: AsyncKey;
    type Value: AsyncStorable;

    // Required methods
    fn get_if_present(&self, key: &Self::Key) -> Option<Self::Value>;
    fn get<'a, 'b, B: FactoryBorrow<Self::Key, Self::Value>>(
        &'a self,
        key: &'a Self::Key,
        factory: B,
    ) -> Pin<Box<dyn Future<Output = Self::Value> + Send + 'b>>;

type Value: AsyncStorable

Required Methods§

Source

fn get_if_present(&self, key: &Self::Key) -> Option<Self::Value>

Source

fn get<'a, 'b, B: FactoryBorrow<Self::Key, Self::Value>>( &'a self, key: &'a Self::Key, factory: B, ) -> Pin<Box<dyn Future<Output = Self::Value> + Send + 'b>>

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
