There's a RankFeatureField case class located under the com.sksamuel.elastic4s.fields package: https://github.com/sksamuel/elastic4s/blob/7154d10e0097cebe5524875f88f6a81f03bb3b26/elastic4s-domain/src/main/scala/com/sksamuel/elastic4s/fields/RankFeatureField.scala

There's no helper constructor methods (in camelCase, e.g. intField) but you should be able to use the case class (in PascalCase) directly.
