WebThe returned hash table is randomized if h was randomized, or the optional random parameter is true, or if the default is to create randomized hash tables; see Hashtbl.create for more information. Hashtbl.rebuild can safely be used to import a hash table built by an old version of the Hashtbl module, then marshaled to persistent storage.

WebAfter a call to Hashtbl.randomize (), hash tables are created in randomized mode by default: Hashtbl.create returns randomized hash tables, unless the ~random:false optional parameter is given. The same effect can be achieved by setting the R parameter in the OCAMLRUNPARAM environment variable.
