Constants

const MapStackThreshold = 32

MapStackThreshold defines common constant for on-stack Attrs sorting.

Functions

func AppendKeyToLabel

func AppendKeyToLabel(buf []byte, key string) []byte

AppendKeyToLabel converts key to label name and appends it to given buffer.

func KeyToLabel

func KeyToLabel(key string) string

KeyToLabel converts key to label name.

Types

type Attrs

type Attrs pcommon.Map

Attrs wraps attributes.

func (Attrs) AsMap

func (m Attrs) AsMap() pcommon.Map

AsMap returns Attrs as pcommon.Map.

func (Attrs) CopyTo

func (m Attrs) CopyTo(target pcommon.Map)

CopyTo copies all attributes from m to target.

func (Attrs) Hash

func (m Attrs) Hash() Hash

Hash computes attributes Hash.

func (Attrs) IsZero

func (m Attrs) IsZero() bool

IsZero whether Attrs is zero value.

func (Attrs) Len

func (m Attrs) Len() int

Len returns number of attributes.

type Hash

type Hash [16]byte

Hash is an attribute hash.

func AttrHash

func AttrHash(m pcommon.Map) Hash

AttrHash computes attributes hash.

func (Hash) String

func (h Hash) String() string

type SpanID

type SpanID [8]byte

SpanID is OpenTelemetry span ID.

func SpanIDFromUint64

func SpanIDFromUint64(v uint64) (r SpanID)

SpanIDFromUint64 creates new SpanID from uint64.

func (SpanID) AsUint64

func (id SpanID) AsUint64() uint64

AsUint64 returns span ID as LittleEndian uint64.

func (SpanID) Hex

func (id SpanID) Hex() string

Hex returns a hex representation of SpanID.

func (SpanID) IsEmpty

func (id SpanID) IsEmpty() bool

IsEmpty returns true if span ID is empty.

type Timestamp

type Timestamp = pcommon.Timestamp

Timestamp is a time specified as UNIX Epoch time in nanoseconds since 1970-01-01 00:00:00 +0000 UTC.

func NewTimestampFromTime

func NewTimestampFromTime(t time.Time) Timestamp

NewTimestampFromTime creates new Timestamp from time.Time.

type TraceID

type TraceID [16]byte

TraceID is OpenTelemetry trace ID.

func ParseTraceID

func ParseTraceID(input string) (_ TraceID, err error)

ParseTraceID parses trace ID from given string.

Deals with missing leading zeroes.

func (TraceID) Hex

func (id TraceID) Hex() string

Hex returns a hex representation of TraceID.

func (TraceID) IsEmpty

func (id TraceID) IsEmpty() bool

IsEmpty returns true if span ID is empty.
