/// Describes a measurement, calculation or setting capability of a device.
///
/// The DeviceMetric resource describes a single measurement, calculation, or
/// setting capability of a medical device, such as a heart rate reading or a
/// PEEP setting on a ventilator. It is derived from the ISO/IEEE 11073-10201
/// Domain Information Model standard but is more widely applicable. Each metric
/// links to its parent Device and can describe its unit of measure, operational
/// status, category, measurement frequency, and any calibrations performed.
/// DeviceMetric instances are commonly referenced by observation and monitoring
/// workflows, where a device produces one or more metrics that are subsequently
/// reported as clinical measurements for a subject such as a [`Patient`](crate::r5::resources::patient::Patient).
///
/// See also: the parent `Device` resource that this metric describes, and
/// [`CodeableConcept`](crate::r5::types::CodeableConcept) for the coded `type`,
/// `unit`, and `category` values used throughout this resource.
///
/// # Examples
///
/// ```
/// use fhir::r5::resources::device_metric::DeviceMetric;
///
/// let value = DeviceMetric::default();
/// let json = ::serde_json::to_value(&value).unwrap();
/// let back: DeviceMetric = ::serde_json::from_value(json).unwrap();
/// assert_eq!(value, back);
/// ```
