Functions

func NewOperator

func NewOperator(opType promql.ItemType) parser.Params

NewOperator creates a new operator based on the type

func NewSelectorFromMatrix

func NewSelectorFromMatrix(n *promql.MatrixSelector) parser.Params

NewSelectorFromMatrix creates a new fetchop

func NewSelectorFromVector

func NewSelectorFromVector(n *promql.VectorSelector) parser.Params

NewSelectorFromVector creates a new fetchop

func Parse

func Parse(q string) (parser.Parser, error)

Parse takes a promQL string and converts parses it into a DAG

Types

type ItemType

type ItemType int

ItemType which maps to ItemType in Prometheus. Note that this is temporary and once we decide we want to use this approach then we will just expose the item types in Prometheus code base
