#substitution_rules ⇒ ::Array<::Google::Cloud::GkeBackup::V1::RestoreConfig::SubstitutionRule>

Returns A list of transformation rules to be applied against Kubernetes resources as they are selected for restoration from a Backup. Rules are executed in order defined - this order matters, as changes made by a rule may impact the filtering logic of subsequent rules. An empty list means no substitution will occur.
