Struct PollStatus 

pub struct PollStatus {
    pub reasons: PrinterReason,
    pub ready_media: Option<ReadyMedia>,
    pub supply_percent: Option<u8>,
}

Live status reported by DeviceBackend::poll_status. Returning None from the poll means “no update”; returning Some(PollStatus) replaces the reasons and, when the optional fields are set, the dynamic media/supply attributes.

Fields

reasons: PrinterReason

Fresh printer-state-reasons.

ready_media: Option<ReadyMedia>

Currently-loaded media, if the device can report it.

supply_percent: Option<u8>

Remaining-supply level 0–100 (e.g. labels left on the roll), if known.
