Hash combinators




Definitions


type hash = int 
A hash value is a positive integer
type 'a t = 'a -> hash 
A hash function for values of type 'a
val const : hash -> 'a t
return h hashes any value into h. Use with caution!.
val int : int t
val bool : bool t
val char : char t
val int32 : int32 t
val int64 : int64 t
val nativeint : nativeint t
val slice : string -> int -> int t
slice s i len state hashes the slice i, ... i+len-1 of s into state
val string : string t
val list : 'a t -> 'a list t
val array : 'a t -> 'a array t
val opt : 'a t -> 'a option t
val pair : 'a t -> 'b t -> ('a * 'b) t
val triple : 'a t -> 'b t -> 'c t -> ('a * 'b * 'c) t
val quad : 'a t ->
'b t -> 'c t -> 'd t -> ('a * 'b * 'c * 'd) t
val if_ : bool -> 'a t -> 'a t -> 'a t
Decide which hash function to use depending on the boolean
val poly : 'a t
the regular polymorphic hash function
val list_comm : 'a t -> 'a list t
Commutative version of CCHash.list. Lists that are equal up to permutation will have the same hash.
Since 1.0
val array_comm : 'a t -> 'a array t
Commutative version of CCHash.array. Arrays that are equal up to permutation will have the same hash.
Since 1.0

Base hash combinators


val combine : 'a t -> hash -> 'a -> hash
val combine2 : hash -> hash -> hash
val combine3 : hash -> hash -> hash -> hash
val combine4 : hash -> hash -> hash -> hash -> hash

Iterators


type 'a sequence = ('a -> unit) -> unit 
type 'a gen = unit -> 'a option 
type 'a klist = unit -> [ `Cons of 'a * 'a klist | `Nil ] 
val seq : 'a t -> 'a sequence t
val gen : 'a t -> 'a gen t
val klist : 'a t -> 'a klist t
