Functions

func Empty

func Empty[T any]() T

Empty returns an empty T type

func Equal

func Equal[T comparable](a, b *T) bool

func Flatten

func Flatten[T any](t **T) *T

Flatten converts a double pointer to a single pointer by referencing if its non-nil

func NonEmptyOrDefault

func NonEmptyOrDefault[T comparable](t T, def T) T

NonEmptyOrDefault returns t if its non-empty, or else def.

func Of

func Of[T any](t T) *T

Of returns a pointer to the input. In most cases, callers should just do &t. However, in some cases Go cannot take a pointer. For example, `ptr.Of(f())`.

func OrDefault

func OrDefault[T any](t *T, def T) T

OrDefault returns *t if its non-nil, or else def.

func OrEmpty

func OrEmpty[T any](t *T) T

OrEmpty returns *t if its non-nil, or else an empty T

func ToList

func ToList[T any](t *T) []T

ToList returns an empty list if t is nil, or a list with a single element

func TypeName

func TypeName[T any]() string

TypeName returns the name of the type
