type SpanID

type SpanID uint64

SpanID is a random 64bit identifier for a span

func NewSpanID

func NewSpanID(v uint64) SpanID

NewSpanID creates a new SpanID from a 64bit unsigned int.

func SpanIDFromString

func SpanIDFromString(s string) (SpanID, error)

SpanIDFromString creates a SpanID from a hexadecimal string

func (SpanID) Marshal

func (s SpanID) Marshal() ([]byte, error)

Marshal converts span ID into a binary representation. Called by protobuf serialization.

func (SpanID) MarshalJSON

func (s SpanID) MarshalJSON() ([]byte, error)

MarshalJSON converts span id into a base64 string enclosed in quotes. Used by protobuf JSON serialization. Example: {1} => "AAAAAAAAAAE=".

func (SpanID) MarshalText

func (s SpanID) MarshalText() ([]byte, error)

MarshalText is called by encoding/json, which we do not want people to use.

func (*SpanID) MarshalTo

func (s *SpanID) MarshalTo(data []byte) (n int, err error)

MarshalTo converts span ID into a binary representation. Called by protobuf serialization.

func (*SpanID) Size

func (s *SpanID) Size() int

Size returns the size of this datum in protobuf. It is always 8 bytes.

func (SpanID) String

func (s SpanID) String() string

func (*SpanID) Unmarshal

func (s *SpanID) Unmarshal(data []byte) error

Unmarshal inflates span ID from a binary representation. Called by protobuf serialization.

func (*SpanID) UnmarshalJSON

func (s *SpanID) UnmarshalJSON(data []byte) error

UnmarshalJSON inflates span id from base64 string, possibly enclosed in quotes. User by protobuf JSON serialization.

There appears to be a bug in gogoproto, as this function is only called for numeric values. https://github.com/gogo/protobuf/issues/411#issuecomment-393856837

func (*SpanID) UnmarshalText

func (s *SpanID) UnmarshalText(text []byte) error

UnmarshalText is called by encoding/json, which we do not want people to use.

func TraceIDFromString(s string) (TraceID, error)

TraceIDFromString creates a TraceID from a hexadecimal string

func (TraceID) Marshal

func (t TraceID) Marshal() ([]byte, error)

Marshal converts trace ID into a binary representation. Called by protobuf serialization.

func (TraceID) MarshalJSON

func (t TraceID) MarshalJSON() ([]byte, error)
