Subject: Missing a function
Date: Sat, 4 Dec 2004 12:05:03 +0100 [thread overview]

Hi,
I have done a comparaison on three data structures of the stdlib of OCaml (I
do parallel implementation of this data structure) and I find that the
module Map does not contain any function for counting the number of elements
of the data structure:
Set, cardinal: t -> int
Hashtbl, lenght : ('a,'b) t -> int
Map, you have to do "let length the_map = fold (fun _ _ i -> i+1)
the_map 0 "
And Set and Hastbl have also fold...
Is there an explanation (or is it just a missing ;-) ) ?
Cheers,
Frédéric Gava
