func ParentBasedErrorAwareSampler

func ParentBasedErrorAwareSampler(samplingRate float64) sdktrace.Sampler

ParentBasedErrorAwareSampler 创建父级感知的概率采样器 - 如果父 Span 已采样，则子 Span 也采样 - 如果父 Span 未采样，则子 Span 也不采样 - 如果是根 Span，按 samplingRate 概率采样

func Shutdown

func Shutdown(ctx context.Context)

func Start

func Start(ctx context.Context, name string, opts ...trace.SpanStartOption) (context.Context, trace.Span)
