Struct PropertySample 

pub struct PropertySample {
    pub path: PropertyPath,
    pub value: Value,
    pub source_ts_ms: Option<i64>,
    pub quality: u32,
}

One piece of telemetry — the value of a property, plus optional timestamp / quality metadata captured at the protocol layer.

Fields

path: PropertyPath

The path the value was read from.

value: Value

The value itself.

source_ts_ms: Option<i64>

Optional protocol-supplied source timestamp, in milliseconds since the Unix epoch. None for protocols (Modbus, MQTT) that do not carry one.

quality: u32

Optional protocol-specific quality code (OPC UA StatusCode, Modbus exception code, …). 0 = good.

Implementations

impl PropertySample

pub fn now(path: PropertyPath, value: Value) -> Self

Construct a fresh sample with no timestamp and quality = 0.
