Functions

func CircleXOR

func CircleXOR(value, src []byte) []byte

CircleXOR performs XOR for 'value' and 'src'. The result is returned as new byte slice. If 'value' is smaller than 'dst', XOR starts from the beginning of 'src'.

func RandTraceID

func RandTraceID() string

RandTraceID returns random traceID in uuid format.

func SetInsTraceID

func SetInsTraceID(ctx context.Context, traceid string) (context.Context, error)

func TraceID

func TraceID(ctx context.Context) string

TraceID returns traceid provided by WithTraceField and ContextWithTrace helpers.

func UInt32ToBytes

func UInt32ToBytes(n uint32) []byte
