All returns a slice of containing metric descriptions for all supported metrics.

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.
