Functions

func ExtendSortedLabels 

func ExtendSortedLabels(lset, extend labels.Labels) labels.Labels

ExtendSortedLabels extend given labels by extend in labels format. The type conversion is done safely, which means we don't modify extend labels underlying array.

In case of existing labels already present in given label set, it will be overwritten by external one. NOTE: Labels and extend has to be sorted.

func HashWithPrefix 

func HashWithPrefix(prefix string, lbls []ZLabel) uint64

HashWithPrefix returns a hash for the given prefix and labels.

func LabelsToPromLabels 

func LabelsToPromLabels(lset []Label) labels.Labels

LabelsToPromLabels convert slice of labelpb.ZLabel to Prometheus labels in type unsafe manner. It reuses the same memory. Caller should abort using passed []Label.

func PromLabelSetsToString 

func PromLabelSetsToString(lsets []labels.Labels) string

func ReAllocZLabelsStrings 

func ReAllocZLabelsStrings(lset *[]ZLabel)

ReAllocZLabelsStrings re-allocates all underlying bytes for string, detaching it from bigger memory pool.

func ZLabelSetsToPromLabelSets 

func ZLabelSetsToPromLabelSets(lss ...ZLabelSet) []labels.Labels

ZLabelSetsToPromLabelSets converts slice of labelpb.ZLabelSet to slice of Prometheus labels.

func ZLabelsToPromLabels 

func ZLabelsToPromLabels(lset []ZLabel) labels.Labels

ZLabelsToPromLabels convert slice of labelpb.ZLabel to Prometheus labels in type unsafe manner. It reuses the same memory. Caller should abort using passed []ZLabel. NOTE: Use with care. ZLabels holds memory from the whole protobuf unmarshal, so the returned Prometheus Labels will hold this memory as well.

type ZLabel 

type ZLabel Label

ZLabel is a Label (also easily transformable to Prometheus labels.Labels) that can be unmarshalled from protobuf reusing the same memory address for string bytes. NOTE: While unmarshalling it uses exactly same bytes that were allocated for protobuf. This mean that *whole* protobuf bytes will be not GC-ed as long as ZLabels are referenced somewhere. Use it carefully, only for short living protobuf message processing.

func DeepCopy 

func DeepCopy(lbls []ZLabel) []ZLabel

DeepCopy copies labels and each label's string to separate bytes.

func ZLabelsFromPromLabels 

func ZLabelsFromPromLabels(lset labels.Labels) []ZLabel

ZLabelsFromPromLabels converts Prometheus labels to slice of labelpb.ZLabel in type unsafe manner. It reuses the same memory. Caller should abort using passed labels.Labels.

func (*ZLabel) Compare 

func (m *ZLabel) Compare(other ZLabel) int

Compare implements proto.Comparer.

Size implements proto.Sizer.

func (*ZLabel) Unmarshal 

func (m *ZLabel) Unmarshal(data []byte) error

Unmarshal unmarshalls gRPC protobuf into ZLabel struct. ZLabel string is directly using bytes passed in `data`. To use it add (gogoproto.customtype) = "github.com/thanos-io/thanos/pkg/store/labelpb.ZLabel" to proto field tag. NOTE: This exists in internal Google protobuf implementation, but not in open source one: https://news.ycombinator.com/item?id=23588882
