Struct AppContext 

pub struct AppContext {
    pub db_context: DbContext,
    pub event_hub: Arc<EventHub>,
    pub shutdown_rx: Receiver<()>,
    pub undo_redo_manager: Arc<Mutex<UndoRedoManager>>,
    pub long_operation_manager: Arc<Mutex<LongOperationManager>>,
    /* private fields */
}

Application context that holds all shared state.

Shutdown lifecycle: when AppContext::shutdown is called the shared shutdown_tx is dropped, which makes every cloned shutdown_rx (held by EventHubClient::start threads) see Disconnected on its next recv() and exit. No polling and no atomic flag needed.

Fields

db_context: DbContext

event_hub: Arc<EventHub>

shutdown_rx: Receiver<()>

Receiver clones are handed to background event-hub threads. Threads exit when the matching sender is dropped via AppContext::shutdown.

undo_redo_manager: Arc<Mutex<UndoRedoManager>>

long_operation_manager: Arc<Mutex<LongOperationManager>>

Implementations

impl AppContext

pub fn new() -> Self

pub fn shutdown(&self)

Signal background event-hub threads to stop. Idempotent — the second call is a no-op because the sender has already been taken.

Trait Implementations

impl Clone for AppContext

fn clone(&self) -> AppContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AppContext

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for AppContext

fn default() -> Self

Returns the “default value” for a type.
