   ### Describe the enhancement requested
   
   ### Describe the enhancement requested
   
   #### Target option
   
   RankOptions
   
   #### Proposed feature
   
   Add support for RankOptions.
   
   #### Impact of this request
   
   It will be used in rank();
   
   ```
   rank(input, {sort_keys=[], null_placement=AtEnd, tiebreaker=First}):
   
   Compute numerical ranks of an array (1-based)
   ----
   This function computes a rank of the input array.
   By default, null values are considered greater than any other value and
   are therefore sorted at the end of the input. For floating-point types,
   NaNs are considered greater than any other non-null value, but smaller
   than null values. The default tiebreaker is to assign ranks in order of
   when ties appear in the input.
   
   The handling of nulls, NaNs and tiebreakers can be changed in RankOptions.
   ```
   
   Currently, only the default option is available from Ruby.
