Functions ¶

func MustNewBaggage ¶

func MustNewBaggage(members ...baggage.Member) baggage.Baggage

MustNewBaggage creates an OTel Baggage containing the provided members. It panics if the baggage cannot be created.

func MustNewMemberRaw(key, value string) baggage.Member

MustNewMemberRaw creates an OTel Baggage member with the provided key and value. It panics if the key or value aren't valid UTF-8 strings.

DO NOT USE this function with dynamic key/value.

func NewTracerProvider ¶

func NewTracerProvider(ctx context.Context, allowNoop bool) (trace.TracerProvider, func(context.Context) error)

func RecordStatus ¶

func RecordStatus(span trace.Span, err error)

RecordStatus records the status of a span based on the error provided.

If err is nil, the span status is unmodified. If err is not nil, the span takes status Error, and the error message is recorded.

Types ¶

type EnvironCarrier ¶

type EnvironCarrier struct {
	TraceParent, TraceState string
}

func PropagateFromEnvironment ¶

func PropagateFromEnvironment() *EnvironCarrier

func (*EnvironCarrier) Environ ¶

func (c *EnvironCarrier) Environ() []string

func (*EnvironCarrier) Get ¶

func (c *EnvironCarrier) Get(key string) string

Get returns the value associated with the passed key.

func (*EnvironCarrier) Keys ¶

func (c *EnvironCarrier) Keys() []string

Keys lists the keys stored in this carrier.

func (*EnvironCarrier) Set ¶

func (c *EnvironCarrier) Set(key, value string)

Set stores the key-value pair.
