Functions

func And

func And[I, O, N any](first func(I) O, second func(O) N) func(I) N

And apply two converters in order.

func AsIs

func AsIs[T any](value T) T

AsIs helper for Map, Flatt

func AsSlice

func AsSlice[T any](value T) []T

AsSlice convert an one element to a slice

func FlattKeys

func FlattKeys[T, K any](element T, keysExtractor func(T) []K) (out []c.KV[K, T])

FlattKeys transforms iterable elements to key/value iterator based on applying key, value extractor to the elements

func FlattValues

func FlattValues[T, V any](element T, valsExtractor func(T) []V) (out []c.KV[T, V])

FlattValues transforms iterable elements to key/value iterator based on applying key, value extractor to the elements

func GetValue

func GetValue[T any](pointer *T) (t T, ok bool)

GetValue returns a value referenced by the pointer or ok==false if the pointer is nil

func Or

func Or[I, O comparable](first func(I) O, second func(I) O) func(I) O

Or applies first Converter, applies second Converter if the first returns zero.

func ToKV

func ToKV[T, K, V any](element T, keyExtractor func(T) K, valExtractor func(T) V) c.KV[K, V]

ToKV transforms one element to one key/value pair

func ToKVs

func ToKVs[T, K, V any](element T, keysExtractor func(T) []K, valsExtractor func(T) []V) (out []c.KV[K, V])

ToKVs transforms one element to multiple key/value pairs slices

func ToPointer

func ToPointer[T any](value T) *T

ToPointer converts a value to the value pointer

func ToSlice

func ToSlice[T any](value T) []T

ToSlice convert an one element to a slice

func ToValue

func ToValue[T any](pointer *T) (t T)

ToValue returns a value referenced by the pointer or the zero value if the pointer is nil
