Struct AppState 

pub struct AppState {
    pub graph: Arc<RwLock<GraphDB>>,
    pub logic: Arc<RwLock<RuleEngine>>,
    pub memory: Arc<RwLock<TitansMemory>>,
    pub broadcaster: Arc<EventBroadcaster>,
    pub proof_store: Arc<ProofStore>,
    pub user_store: Arc<UserStore>,
}

The shared state accessible by all API handlers.

This struct uses Arc and RwLock to provide safe, concurrent access to the application’s core components like the database and logic engine.

Fields

graph: Arc<RwLock<GraphDB>>

A thread-safe reference to the graph database.

logic: Arc<RwLock<RuleEngine>>

A thread-safe reference to the logic and validation engine.

memory: Arc<RwLock<TitansMemory>>

The Titans dual-memory system (STM + LTM with consolidation).

broadcaster: Arc<EventBroadcaster>

The event broadcaster for sending real-time updates to WebSocket subscribers.

proof_store: Arc<ProofStore>

The store for managing and verifying zero-knowledge proofs.

user_store: Arc<UserStore>

The user store for authentication and authorization.

This field is only available if the auth feature is enabled.

Implementations

impl AppState

pub fn new() -> Self

Creates a new AppState with an in-memory graph database. This is useful for testing or development environments.

pub fn with_graph(graph: GraphDB) -> Self

Creates a new AppState with a pre-configured GraphDB instance.

pub fn cortex_client(&self) -> CortexInternalClient

Returns an internal Cortex client configured for same-process access.

This client calls the Cortex REST API and can be used by host functions to bridge WASM zome code with the semantic graph.

pub async fn stats(&self) -> GraphStats

Gathers and returns statistics about the graph and connected clients.

Trait Implementations

impl Clone for AppState

fn clone(&self) -> AppState

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for AppState

fn default() -> Self

Returns the “default value” for a type.
