-- The following record fields are available, with the corresponding lenses provided
-- for backwards compatibility:
--
-- 'boolValue', 'variableValue_boolValue' - If this feature uses the Boolean variation type, this field contains the
-- Boolean value of this variation.

-- long value of this variation.
--
-- 'stringValue', 'variableValue_stringValue' - If this feature uses the string variation type, this field contains the
-- string value of this variation.
