Functions

func DefaultIfNil added in v0.15.0 

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

DefaultIfNil returns the dereferenced value of the pointer, or the zero value of T if the pointer is nil. Deprecated: use Deref instead.

func Deref added in v0.15.0 

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

Deref returns the value referenced by the given pointer. If the pointer is nil, a zero value is returned.

func DerefOrElse added in v0.15.0 

func DerefOrElse(val *string, def string) string

func EnsureTypedList added in v0.14.0 

func EnsureTypedList(ctx context.Context, list types.List, elemType attr.Type) types.List
