Functions

func ExtendSortedLabels added in v0.18.0 

func ExtendSortedLabels(lset labels.Labels, 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 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 ZLabelSetsToPromLabelSets added in v0.17.0 

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

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

func ZLabelsToPromLabels added in v0.17.0 

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.

Types

}

func LabelsFromPromLabels 

func LabelsFromPromLabels(lset labels.Labels) []Label

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

type ZLabel added in v0.17.0 

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 unmarshal use exactly same bytes that were allocated for protobuf, this will 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 added in v0.17.0 

func DeepCopy(lbls []ZLabel) []ZLabel

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

func ZLabelsFromPromLabels added in v0.17.0 

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.
