module Integer_desc:sig..end
hash and cmp function for Mapred_sorters.generic_sorter.
The functions are defined so that the records are sorted in an
descending way by key. The key is interpreted as integer (digits
0 to 9, possibly prefixed by + or -). Characters violating the
integer syntax are silently ignored. (Note that the integer range
is not restricted!)val hash : string -> int -> int -> intval cmp : string -> int -> int -> string -> int -> int -> int
