Functions

func AsString

func AsString(key, value string) string

Helper function to refactor key value label manipulation

func ParseLabel

func ParseLabel(label string) (string, string, error)

ParseLabel given a string label converts into key=val

func ParseLabels

func ParseLabels(labels []string) (map[string][]string, error)

ParseLabels given a list of string labels, returns them as key=[val] map a list of values is needed because keys can be duplicate

Types

type LabelSelector

type LabelSelector[T Labeled] struct {
	// contains filtered or unexported fields
}

func NewLabelSelector

func NewLabelSelector[T Labeled](expr string, match MatchAny) (*LabelSelector[T], error)

NewRuleSelector returns a new rule selector that works on rule labels it enables using string expressions to form complex label queries supports "&&", "||" and "!" operators, "(" ")" for grouping, operands are string labels in key=val format, keys can be subdomain prefixed

func (*LabelSelector[T]) MatchList

func (l *LabelSelector[T]) MatchList(list []T) ([]T, error)

func (*LabelSelector[T]) Matches

func (l *LabelSelector[T]) Matches(v T) (bool, error)

type Labeled

type Labeled interface {
	GetLabels() []string
}

type MatchAny

type MatchAny func(elem string, items []string) bool
