Trait LoadState 

pub trait LoadState<ID: EventId, S, E: Event + Clone> {
    // Required method
    fn load<'life0, 'async_trait>(
        &'life0 self,
        state_query: S,
    ) -> Pin<Box<dyn Future<Output = Result<LoadedState<ID, S>, BoxDynError>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

Trait to load a state.

This trait for loading a state from the storage backend.

Required Methods

fn load<'life0, 'async_trait>( &'life0 self, state_query: S, ) -> Pin<Box<dyn Future<Output = Result<LoadedState<ID, S>, BoxDynError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Loads the state based on the provided state query.

This method retrieves a state from the storage backend, along with its version.

Parameters

• state_query: The query object representing the desired state to hydrate.

Returns

the loaded state, or an error if the load fails.

Dyn Compatibility

This trait is dyn compatible.

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