Measurement (tezos-time-measurement.Tezos_time_measurement

type label = string

The name of a measurement.

type metadata = string list

Some additional data that can be used to discrimine measurements.

type key = label * metadata

The key of a measurement is used to discriminate measurements. It is intended to be used as a search criteria if measurements are stored in a collection.

type value = float

The value of a measurement. It can actually represent both a duration or a timestamp.

type t = key * value
