Functions

func ConvertSettingsKeyToTFFieldKey added in v0.15.2

ConvertSettingsKeyToTFFieldKey maps a dotted Elasticsearch settings key to the Terraform attribute name used in flattened blocks (dots → underscores).

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
