Struct OpcReadResponse 

pub struct OpcReadResponse {
    pub tag: String,
    pub value: String,
    pub quality: SampleQuality,
    pub timestamp: Option<DateTime<Utc>>,
}

Response body of GET /api/opc/read.

quality reuses SampleQuality rather than a third quality representation – bhtune-db’s SampleQuality (mapped from the driver’s live bhtune_driver::Quality by sample_quality_from_driver) is already exposed directly over HTTP in GET /api/runs/{id}’s SampleResponse::pv_quality (see routes::history), so this follows that same precedent instead of inventing a parallel OpcQualityResponse enum.

Fields

tag: String

value: String

quality: SampleQuality

timestamp: Option<DateTime<Utc>>

Always null for the OPC DA driver today: the gateway’s last-change time is a local, offset-less string with no reliable way to convert it to a trustworthy DateTime<Utc> (see bhtune_driver::opcda::tag_value_from_raw’s doc comment) – kept as a field rather than dropped entirely so a future driver that can supply a trustworthy instant (or a bridge protocol revision that reports the gateway’s own timezone) doesn’t need an API shape change to start populating it.
