Functions

func MapToSlice

func MapToSlice[T any](mapping *Mapping, input map[string]T) []T

MapToSlice converts the given map to a slice according to the provided mapping. Keys not in the mapping are dropped.

func SliceToMap

func SliceToMap[T any](mapping *Mapping, input []T) map[string]T

SliceToMap converts the given slice to a map according to the provided mapping.

Types

type Mapping

type Mapping struct {
	MaxIndex    int
	NameToIndex map[string]int
	IndexToName map[int]string
}

Mapping contains translation of names to indexes and vice versa, which allows maps of well-known keys to be converted to slices of just values with more compact JSON representations.

func NewMapping

func NewMapping(fwd map[string]int) *Mapping

NewMapping creates a new Mapping given the provided name-to-index map.
