Struct AppState 

pub struct AppState<S: WorkflowStore> {
    pub engine: Arc<Engine<S>>,
    pub event_tx: Sender<BroadcastEvent>,
    pub auth_mode: AuthMode,
    pub binary_version: Option<&'static str>,
}

Shared state for all API handlers.

Fields

engine: Arc<Engine<S>>

event_tx: Sender<BroadcastEvent>

auth_mode: AuthMode

binary_version: Option<&'static str>

Version of the containing binary (e.g. the assay-lua CLI) — set by embedders so /api/v1/version reflects the user-facing binary, not this internal engine-crate version. Defaults to the assay-workflow crate version, which is what the dashboard falls back to when an embedder doesn’t override.
