func (a *KVLogger) Debug(msg string, attributes ...tab.Attribute)

func (*KVLogger) Error ¶ added in v0.1.3

func (a *KVLogger) Error(err error, attributes ...tab.Attribute)

func (*KVLogger) Fatal ¶ added in v0.1.3

func (a *KVLogger) Fatal(msg string, attributes ...tab.Attribute)

func (*KVLogger) Info ¶ added in v0.1.3

func (*Span) AddAttributes ¶

func (s *Span) AddAttributes(attributes ...tab.Attribute)

AddAttributes a tags to the span.

If there is a pre-existing tag set for `key`, it is overwritten.

func (*Span) End ¶

func (s *Span) End()

End sets the end timestamp and finalizes Span state.

With the exception of calls to Context() (which are always allowed), Finish() must be the last call made to any span instance, and to do otherwise leads to undefined behavior.

func (*Span) Inject ¶

func (s *Span) Inject(carrier tab.Carrier) error

Inject span context into carrier

func (*Span) InternalSpan ¶

func (s *Span) InternalSpan() interface{}

InternalSpan returns the real implementation of the Span

func (*Span) Logger ¶

func (s *Span) Logger() tab.Logger

Logger returns a trace.Logger for the span

func (*Trace) FromContext ¶

func (t *Trace) FromContext(ctx context.Context) tab.Spanner

FromContext returns the `Span` previously associated with `ctx`, or `nil` if no such `Span` could be found.

func (*Trace) NewContext ¶

func (t *Trace) NewContext(ctx context.Context, span tab.Spanner) context.Context

NewContext returns a new context with the given Span attached.

func (*Trace) StartSpan ¶

func (t *Trace) StartSpan(ctx context.Context, operationName string, opts ...interface{}) (context.Context, tab.Spanner)

StartSpan starts and returns a Span with `operationName`, using any Span found within `ctx` as a ChildOfRef. If no such parent could be found, StartSpanFromContext creates a root (parentless) Span.

func (*Trace) StartSpanWithRemoteParent ¶

func (t *Trace) StartSpanWithRemoteParent(ctx context.Context, operationName string, carrier tab.Carrier, opts ...interface{}) (context.Context, tab.Spanner)

StartSpanWithRemoteParent starts and returns a Span with `operationName`, using reference span as FollowsFrom
