Read populates each Value field in the given slice of metric samples.

KindBad indicates that the Value has no type and should not be used.

KindFloat64 indicates that the type of the Value is a float64.

KindFloat64Histogram indicates that the type of the Value is a *Float64Histogram.

KindUint64 indicates that the type of the Value is a uint64.

Description describes a runtime metric.

Float64Histogram represents a distribution of float64 values.

Sample captures a single metric sample.

Value represents a metric value returned by the runtime.

ValueKind is a tag for a metric Value which indicates its type.
