Function archive_export_request_subject 

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

Builds the NATS request subject that the exporter serves archive exports on.

Always uses the structured layout <root>.<site>.<box>.<source>.export.request, whatever the root, with every token passed through sanitize_token. Missing or empty IDs become unknown-site and unknown-box, and the source is chosen by source_token exactly as for the live subjects, so the webapp reaches the exporter with the subject it derives from the source’s config.

Arguments

• nats_subject - Subject root, for example avenars.
• asset - Asset number, the last-resort source token, if known.
• site_id - Site ID.
• box_id - Box ID.
• labjack_name - LabJack name, used as the source when source_id is not set.
• source_type - Accepted for config compatibility; not used in the subject.
• source_id - Source ID.

Examples

("avenars", None, Some("i69"), Some("i69-mu1"), None, Some("labjack"), Some("i69-lj2"))
    -> "avenars.i69.i69-mu1.i69-lj2.export.request"
("avenars", Some(42), None, None, None, None, None)
    -> "avenars.unknown-site.unknown-box.asset042.export.request"
