var (

	// DefaultLogFieldKey is the log field key which translates directly into Zipkin's Annotation.Value,
	// provided it's the only field in the log.
	// In all other cases the fields are encoded into Annotation.Value as JSON string.
	// TODO move to domain model

Functions

func ToDomain

func ToDomain(zSpans []*zipkincore.Span) (*model.Trace, error)

ToDomain transforms a trace in zipkin.thrift format into model.Trace. The transformation assumes that all spans have the same Trace ID. A valid model.Trace is always returned, even when there are errors. The errors are more of an "fyi", describing issues in the data. TODO consider using different return type instead of `error`.

func ToDomainSpan

func ToDomainSpan(zSpan *zipkincore.Span) ([]*model.Span, error)

ToDomainSpan transforms a span in zipkin.thrift format into model.Span. A valid model.Span is always returned, even when there are errors. The errors are more of an "fyi", describing issues in the data. TODO consider using different return type instead of `error`.
