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 ExtraKeys

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

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

func ExtraVals

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

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

func KeyValue

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

KeyValue transforms one element to one key/value pair

func KeysValues

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

KeysValues transforms one element to multiple key/value pairs slices

func NoNilPtrVal

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

NoNilPtrVal 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 Ptr

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

Ptr converts a value to the value pointer

func PtrVal

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

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

func ToSlice

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

ToSlice convert an one element to a slice
