Struct WatchdogConfig 

pub struct WatchdogConfig {
    pub threshold: Duration,
    pub heartbeat_interval: Duration,
    pub poll_interval: Duration,
    pub on_stall: Option<StallCallback>,
    pub emit_event: bool,
}

Fields

threshold: Duration

A heartbeat older than this is a stall.

heartbeat_interval: Duration

How often the main thread is pinged. The floor is 10 ms.

poll_interval: Duration

The shortest the watchdog thread waits between two looks at the heartbeat, which bounds how late a stall is reported past the threshold. Default 250 ms; the floor is 10 ms. The thread no longer polls at this rate: idle it sleeps until the last beat plus the threshold can have passed, so a larger value only widens the allowed lateness and a smaller one only shrinks it.

on_stall: Option<StallCallback>

Called once per stall episode with the stall duration (see StallReport::stalled_ms), on the watchdog thread. A host can use it to write a hang dump. It runs before the rightkit-shell://stall event.

emit_event: bool

Also emit the rightkit-shell://stall event to the webview. Default true.

Hazard: the event is emitted from the watchdog thread through the AppHandle, and that thread exists to observe an app that may be deadlocked. Emitting takes app-side locks, so a deadlock in the app can stop the watchdog thread too, at the moment its report matters most. Set false for callback-only mode: the poll thread then touches only std atomics and on_stall (it is not even given an AppHandle). A failed emit never ends the loop in either mode; it is counted in WatchdogStatus::emit_failures.
