Expand description

Reponsible for managing states for a specific object

With this trait one can load/save individual states from an orig (Self) object

Provided Methods§

Source

fn load_state<'life0, 'life1, 'async_trait, T, S>( &'life0 mut self, state_loader: &'life1 S, ) -> Pin<Box<dyn Future<Output = Result<(), LoadStateError>> + Send + 'async_trait>>
where T: IdentifiableType + Serialize + DeserializeOwned + Default + 'async_trait, S: StateLoader<T> + Send + Sync + 'async_trait, Self: State<T> + IdentifiableType + WithId + Send + Sync + Send + 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Load the state from the backend, deserialize it, and map it into the right state

Source

fn save_state<'life0, 'life1, 'async_trait, T, S>( &'life0 self, state_saver: &'life1 S, ) -> Pin<Box<dyn Future<Output = Result<(), LoadStateError>> + Send + 'async_trait>>
where T: IdentifiableType + Serialize + DeserializeOwned + Sync + Default + 'async_trait, S: StateSaver<T> + 'async_trait, Self: State<T> + IdentifiableType + WithId + Send + Sync + Sync + 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Serialize the data out of the state and save it to the backend provided

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.
