Struct CaptureSession 

pub struct CaptureSession { /* private fields */ }

Per-print capture state. One session captures one print: it watches for the print to be active (optionally waiting for it), emits a CaptureAction::Capture on each new layer that passes the every filter, and Stops when the print reaches a terminal state or errors.

Implementations

impl CaptureSession

pub fn new(every: u64, wait: bool) -> Self

every = capture every Nth layer (clamped to >= 1). wait = sit through idle/finished/stale-error states until a print becomes active (so the session can be started before the print), rather than stopping at once.

pub fn frames(&self) -> u64

Frames emitted so far (the last Capture’s frame_no).

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

Feed one status snapshot; get the action to take.
