Struct StateRegistry 

pub struct StateRegistry {
    database: SystemDatabase,
    client_managed: RwLock<HashMap<TypeId, Box<dyn Any + Send + Sync>>>,
}

A registry that contains repositories for different types of items. These repositories can be either managed by the client or by the SDK itself.

Fields

database: SystemDatabase

client_managed: RwLock<HashMap<TypeId, Box<dyn Any + Send + Sync>>>

Implementations

impl StateRegistry

pub fn new_with_memory_db() -> Self

Creates a new StateRegistry backed by an in-memory database.

pub async fn new_with_db( configuration: DatabaseConfiguration, migrations: RepositoryMigrations, ) -> Result<Self, DatabaseError>

Creates a new StateRegistry backed by a database.

pub fn setting<T>(&self, key: Key<T>) -> Result<Setting<T>, StateRegistryError>

Get a handle to a setting by its type-safe key.

pub fn register_client_managed<T: RepositoryItem>( &self, value: Arc<dyn Repository<T>>, )

Registers a client-managed repository into the map, associating it with its type.

fn get_client_managed<T: RepositoryItem>( &self, ) -> Option<Arc<dyn Repository<T>>>

Retrieves a client-managed repository from the map given its type.

fn get_sdk_managed<T: RepositoryItem>( &self, ) -> Result<Arc<dyn Repository<T>>, StateRegistryError>

Retrieves a SDK-managed repository from the database.

pub fn get<T>(&self) -> Result<Arc<dyn Repository<T>>, StateRegistryError>

where T: RepositoryItem,

Get a repository with fallback: prefer client-managed, fall back to SDK-managed.

This method first attempts to retrieve a client-managed repository. If not found, it falls back to an SDK-managed repository. Both are returned as Arc<dyn Repository<T>>.

Errors

This method never fails, but returns a Result for backwards compatibility.
