AddLoggingRoundTripper adds logging for long round trips to http.RoundTripper.

EmptyTimeSeries constructs a new empty TimeSeries.

IDsToJSON embeds a list of string IDs in a data structure that serializes to JSON like [{"id":"first"},{"id":"second"}].

ParseTimeSeries parses the JSON representation of a time series, or returns an empty time series if the input is the empty string.

UnpackError is usually a no-op, but for some Gophercloud errors, it removes the outer layer that obscures the better error message hidden within.

TimeSeries is a minimalistic implementation of a time series (a representation of a metric that assumes different values over time), tailored towards the exact needs of the project_az_resources.historical_usage attribute.

YamlRawMessage is like json.RawMessage: During yaml.Unmarshal(), it will just collect the provided YAML representation instead of parsing it into a specific datatype.
