Types

type Cleanup

type Cleanup func()

func ConfigureProvider

func ConfigureProvider(cfg *Config) (pt trace.Provider, cl Cleanup, err error)

type Config

type Config struct {
	ExporterType    ExporterType
	ServiceName     string
	RuntimeProvider bool

	// Jaeger config
	JaegerHost string
}

type ExporterType

type ExporterType int

const (
	ExporterTypeNone ExporterType = iota
	ExporterTypeStdout
	ExporterTypeJaeger
)

type RuntimeProvider

type RuntimeProvider struct {
	// contains filtered or unexported fields
}

func NewRuntimeProvider

func NewRuntimeProvider(root trace.Provider) *RuntimeProvider

func (*RuntimeProvider) Tracer

func (rp *RuntimeProvider) Tracer(name string, opts ...trace.TracerOption) trace.Tracer

type RuntimeTracer

type RuntimeTracer struct {
	// contains filtered or unexported fields
}

func (*RuntimeTracer) Start

func (rt *RuntimeTracer) Start(ctx context.Context, spanName string, opts ...trace.StartOption) (context.Context, trace.Span)

Start identical to original start span, but automatically add runtime information to the span

func (*RuntimeTracer) WithSpan

func (rt *RuntimeTracer) WithSpan(ctx context.Context, spanName string, fn func(ctx context.Context) error, opts ...trace.StartOption) error

WithSpan is identical to original start span, but automatically add runtime information to the span
