	// StringType indicates the value is a unicode string
	StringType = ValueType_STRING
	// BoolType indicates the value is a Boolean encoded as int64 number 0 or 1
	BoolType = ValueType_BOOL

Functions

func DurationAsMicroseconds

func EpochMicrosecondsAsTime 

func EpochMicrosecondsAsTime(ts uint64) time.Time

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

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.
