Struct PrintActivitySession 

pub struct PrintActivitySession { /* private fields */ }

Tracks only a print’s lifecycle (active → ended), no layer logic — for a runner that samples frames on its own clock (a wall-time interval) rather than per layer. Shares the active/stop rules with CaptureSession so both agree on when a print starts and ends.

Implementations

impl PrintActivitySession

pub fn new(wait: bool) -> Self

wait = sit through idle/finished until a print becomes active (so the runner can be armed before the print starts), rather than stopping at once.

pub fn observe(&mut self, s: &PrinterStatus) -> ActivityAction

Feed the current status (call on each sampling tick). Stop takes priority over Capture so a finishing print ends cleanly instead of grabbing once more.
