Functions

func DurationAsMicroseconds

func EpochMicrosecondsAsTime

func EpochMicrosecondsAsTime(ts uint64) time.Time

EpochMicrosecondsAsTime converts microseconds since epoch to time.Time value.

func HashCode

func HashCode(o Hashable) (uint64, error)

HashCode calculates a FNV-1a hash code for a Hashable object.

func MicrosecondsAsDuration

func MicrosecondsAsDuration(v uint64) time.Duration

MicrosecondsAsDuration converts duration in microseconds to time.Duration value.

func SortSpan

func SortSpan(span *Span)

SortSpan deep sorts a span: this sorts its tags, logs by timestamp, tags in logs, and tags in process.

func SortTrace

func SortTrace(trace *Trace)

SortTrace deep sorts a trace's spans by SpanID.

func SortTraceIDs

func SortTraceIDs(traceIDs []*TraceID)

SortTraceIDs sorts a list of TraceIDs

func SortTraces

func SortTraces(traces []*Trace)

Types

type Batch

type Batch struct {
	Spans                []*Span  `protobuf:"bytes,1,rep,name=spans,proto3" json:"spans,omitempty"`
	Process              *Process `protobuf:"bytes,2,opt,name=process,proto3" json:"process,omitempty"`
	XXX_NoUnkeyedLiteral struct{} `json:"-"`
	XXX_unrecognized     []byte   `json:"-"`
	XXX_sizecache        int32    `json:"-"`
}

Note that both Span and Batch may contain a Process. This is different from the Thrift model which was only used for transport, because Proto model is also used by the backend as the domain model, where once a batch is received it is split into individual spans which are all processed independently, and therefore they all need a Process. As far as on-the-wire semantics, both Batch and Spans in the same message may contain their own instances of Process, with span.Process taking priority over batch.Process.

UnmarshalJSON inflates span id from base64 string, possibly enclosed in quotes. User by protobuf JSON serialization.

There appears to be a bug in gogoproto, as this function is only called for numeric values. https://github.com/gogo/protobuf/issues/411#issuecomment-393856837

func MaybeAddParentSpanID

func MaybeAddParentSpanID(traceID TraceID, parentSpanID SpanID, refs []SpanRef) []SpanRef

MaybeAddParentSpanID adds non-zero parentSpanID to refs as a child-of reference.
