Functions

func NewTracer

func NewTracer(ctx context.Context, logger log.Logger, metrics *prometheus.Registry, conf []byte) (opentracing.Tracer, io.Closer, error)

NewTracer create tracer from YAML.

func ParseConfigFromYaml

func ParseConfigFromYaml(cfg []byte) (*config.Configuration, error)

ParseConfigFromYaml uses config YAML to set the tracer's Configuration.
