Functions

func Extract

func Extract(ctx context.Context, tracer trc.Tracer, request *fasthttp.Request) (rCtx context.Context, span trc.Span)

extract trace and span id from header, if trace id not exist create new span context for start new tracer and return trace span

func Inject

func Inject(ctx context.Context, tracer trc.Tracer, request *fasthttp.Request) (context.Context, trc.Span)

inject trace id and span id to request header and start new tracer

func StartAgent

func StartAgent(c AgentConfig) (func(ctx context.Context) error, error)

start new connection to collector server for now only support otpl that using jaeger and prometheus
