Elpi_runtime.PtmapMaps over integers implemented as Patricia trees.
The following signature is a subset of Map.S with type key = int, with the same specifications (not repeated here) unless specified otherwise.
These are little-endian Patricia trees, so there is no efficient ordering of keys within the structure. Consequently,
min/max_binding, find_first/last are rather inefficient (linear)iter, fold *do not* iterate in the key orderbindings is *not sorted* by keysval empty : 'a tval is_empty : 'a t -> boolval cardinal : 'a t -> intval find_unifiables : int -> 'a t -> 'a listval to_list : 'a t -> (int * 'a) listval pp : (Format.formatter -> 'a -> unit) -> Format.formatter -> 'a t -> unitval show : (Format.formatter -> 'a -> unit) -> 'a t -> string
