Functions ¶
func CreateChildSpan ¶
CreateChildSpan takes a message part, extracts an existing span if there is one and returns child span.
func CreateChildSpans ¶
CreateChildSpans takes a message, extracts spans per message part and returns a slice of child spans. The length of the returned slice is guaranteed to match the message size.
func FinishSpans ¶
FinishSpans calls Finish on all message parts containing a span.
func GetSpan ¶
GetSpan returns a span attached to a message part. Returns nil if the part doesn't have a span attached.
func InitSpans ¶
InitSpans sets up OpenTracing spans on each message part if one does not already exist.
func InitSpansFromParent ¶
InitSpansFromParent sets up OpenTracing spans as children of a parent span on each message part if one does not already exist.
func IterateWithChildSpans ¶
func IterateWithChildSpans(operationName string, msg types.Message, iter func(int, opentracing.Span, types.Part) error) error
IterateWithChildSpans iterates all the parts of a message and, for each part, creates a new span from an existing span attached to the part and calls a func with that span before finishing the child span.
func WithChildSpans ¶
WithChildSpans takes a message, extracts spans per message part, creates new child spans, and returns a new message with those spans embedded. The original message is unchanged.
