Functions

func GenerateW3CSpanID

func GenerateW3CSpanID() string

GenerateW3CSpanID returns a 16-character hex string (8 random bytes) compatible with the W3C Trace Context specification.

func GenerateW3CTraceID

func GenerateW3CTraceID() string

GenerateW3CTraceID returns a 32-character hex string (16 random bytes) compatible with the W3C Trace Context specification.

func New

func New() string

New generates a unique trace/span ID. It combines a timestamp component with a random component and an atomic counter for uniqueness. Uses math/rand (not crypto/rand) for performance — these IDs are used for log correlation and distributed tracing, not for security purposes.
