type Writer

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

Writer writes a sequence of trace spans to a specified export function.

func NewWriter

func NewWriter(export func(spans *protos.TraceSpans) error) *Writer

NewWriter creates a Writer that writes a sequence of trace spans to a specified export function.

func (*Writer) ExportSpans
