Struct AppState 

pub struct AppState {
    pub settings: Arc<Settings>,
    pub conn: Arc<Mutex<Connection>>,
}

Application state shared by every route. The single SQLite connection is wrapped in a Mutex since rusqlite is sync-only; handlers acquire the lock briefly. For long-running queries we’d spawn_blocking, but the workload here is microsecond-scale.

Fields

settings: Arc<Settings>

conn: Arc<Mutex<Connection>>
