Variables ¶

var ErrMetricKindMismatch = fmt.Errorf(
	"A metric was already registered by this name with another kind or number type")

ErrMetricKindMismatch is the standard error for mismatched metric instrument definitions.

Functions ¶

func Compatible ¶

func Compatible(candidate, existing metric.Descriptor) bool

Compatible determines whether two metric.Descriptors are considered the same for the purpose of uniqueness checking.

func NewMetricKindMismatchError ¶

func NewMetricKindMismatchError(desc metric.Descriptor) error

NewMetricKindMismatchError formats an error that describes a mismatched metric instrument definition.

func NewUniqueInstrumentMeterImpl ¶

func NewUniqueInstrumentMeterImpl(impl metric.MeterImpl) metric.MeterImpl

NewUniqueInstrumentMeterImpl returns a wrapped metric.MeterImpl with the addition of uniqueness checking.

Types ¶

type MeterProvider ¶

type MeterProvider struct {
	// contains filtered or unexported fields
}

MeterProvider is a standard MeterProvider for wrapping `MeterImpl`

func NewMeterProvider ¶

func NewMeterProvider(impl metric.MeterImpl) *MeterProvider

NewMeterProvider returns a new provider that implements instrument name-uniqueness checking.

func (*MeterProvider) Meter ¶

func (p *MeterProvider) Meter(instrumentationName string, opts ...metric.MeterOption) metric.Meter

Meter implements MeterProvider.
