Types

type MustFloat64Meter

type MustFloat64Meter interface {
	// Counter returns a new instrument identified by name and configured
	// with options. The instrument is used to synchronously record increasing
	// float64 measurements during a computational operation.
	Counter(name string, options ...metric.Float64CounterOption) metric.Float64Counter
	// UpDownCounter returns a new instrument identified by name and
	// configured with options. The instrument is used to synchronously record
	// float64 measurements during a computational operation.
	UpDownCounter(name string, options ...metric.Float64UpDownCounterOption) metric.Float64UpDownCounter
	// Histogram returns a new instrument identified by name and
	// configured with options. The instrument is used to synchronously record
	// the distribution of float64 measurements during a computational operation.
	Histogram(name string, options ...metric.Float64HistogramOption) metric.Float64Histogram
}

MustFloat64Meter is a meter/Meter which panics if it cannot successfully build the requestd counter, upDownCounter or histogram.

func MustFloat64

func MustFloat64() MustFloat64Meter

MustFloat64 returns an instrument provider based on the global Meter. The returns provider panics instead of returning an error when it cannot build a required counter, upDownCounter or histogram.

type MustInt64Meter

type MustInt64Meter interface {
	// Counter returns a new instrument identified by name and configured
	// with options. The instrument is used to synchronously record increasing
	// int64 measurements during a computational operation.
	Counter(name string, options ...metric.Int64CounterOption) metric.Int64Counter
	// UpDownCounter returns a new instrument identified by name and
	// configured with options. The instrument is used to synchronously record
	// int64 measurements during a computational operation.
	UpDownCounter(name string, options ...metric.Int64UpDownCounterOption) metric.Int64UpDownCounter
	// Histogram returns a new instrument identified by name and
	// configured with options. The instrument is used to synchronously record
	// the distribution of int64 measurements during a computational operation.
	Histogram(name string, options ...metric.Int64HistogramOption) metric.Int64Histogram
}

MustInt64Meter is a meter/Meter which panics if it cannot successfully build the requestd counter, upDownCounter or histogram.

func MustInt64

func MustInt64() MustInt64Meter

MustInt64 returns an instrument provider based on the global Meter. The returns provider panics instead of returning an error when it cannot build a required counter, upDownCounter or histogram.
