Function live_labjack_channel_subject 

pub fn live_labjack_channel_subject(
    nats_subject: &str,
    asset: u32,
    channel: u8,
    site_id: Option<&str>,
    box_id: Option<&str>,
    labjack_name: Option<&str>,
    source_type: Option<&str>,
    source_id: Option<&str>,
) -> String

Builds the live-data subject for one LabJack channel.

Legacy configs use <root>.<asset>.data.<channel>, with the root used as given. Structured configs use <root>.<site>.<box>.<source>.live.<channel>, with every token passed through sanitize_token. In the structured layout a missing or empty site or box becomes unknown-site or unknown-box, and the source is chosen by source_token: the first of source_id, labjack_name or asset<NNN> that is set.

Arguments

• nats_subject - Subject root, for example avenabox or avenars.
• asset - Asset number. Used in the legacy layout and as the last-resort source token in the structured layout.
• channel - LabJack channel number, formatted by pad_channel.
• site_id - Site ID for the structured layout.
• box_id - Box ID for the structured layout.
• labjack_name - LabJack name, used as the source when source_id is None.
• source_type - Accepted for config compatibility; not used in the subject.
• source_id - Source ID for the structured layout.
