val add_exn : ('a, 'b) t -> key:'a key -> data:'b -> unit
val change : ('a, 'b) t -> 'a key -> f:('b option -> 'b option) -> unit

change t key ~f changes t's value for key to be f (find t key).

val update : ('a, 'b) t -> 'a key -> f:('b option -> 'b) -> unit

update t key ~f is change t key ~f:(fun o -> Some (f o)).

val add_multi : ('a, 'b list) t -> key:'a key -> data:'b -> unit

add_multi t ~key ~data if key is present in the table then cons data on the list, otherwise add key with a single element list.

val remove_multi : ('a, _ list) t -> 'a key -> unit

remove_multi t key updates the table, removing the head of the list bound to key. If the list has only one element (or is empty) then the binding is removed.

val map : ('c, ('a, 'b) t -> f:('b -> 'c) -> ('a, 'c) t) map_options

map t f returns new table with bound values replaced by f applied to the bound values

val mapi : ('c, ('a, 'b) t -> f:(key:'a key -> data:'b -> 'c) -> ('a, 'c) t) map_options

like map, but function takes both key and data as arguments

val filter_map : ('c, ('a, 'b) t -> f:('b -> 'c option) -> ('a, 'c) t) map_options

returns new map with bound values filtered by f applied to the bound values

val filter_mapi : ('c, ('a, 'b) t -> f:(key:'a key -> data:'b -> 'c option) -> ('a, 'c) t) map_options

like filter_map, but function takes both key and data as arguments

val filter : ('a, 'b) t -> f:('b -> bool) -> ('a, 'b) t
val filteri : ('a, 'b) t -> f:(key:'a key -> data:'b -> bool) -> ('a, 'b) t
val partition_map : ('c, ('d, ('a, 'b) t -> f:('b -> [
| `Fst of 'c
| `Snd of 'd
]) -> ('a, 'c) t * ('a, 'd) t) map_options) map_options

returns new maps with bound values partitioned by f applied to the bound values

val partition_mapi : ('c, ('d, ('a, 'b) t -> f:(key:'a key -> data:'b -> [
| `Fst of 'c
| `Snd of 'd
]) -> ('a, 'c) t * ('a, 'd) t) map_options) map_options

like partition_map, but function takes both key and data as arguments

val partition_tf : ('a, 'b) t -> f:('b -> bool) -> ('a, 'b) t * ('a, 'b) t
val partitioni_tf : ('a, 'b) t -> f:(key:'a key -> data:'b -> bool) -> ('a, 'b) t * ('a, 'b) t
val find_or_add : ('a, 'b) t -> 'a key -> default:(unit -> 'b) -> 'b

find_or_add t k ~default returns the data associated with key k if it is in the table t, otherwise it lets d = default() and adds it to the table.

val find : ('a, 'b) t -> 'a key -> 'b option

find t k returns Some (the current binding) of k in t, or None if no such binding exists

val find_exn : ('a, 'b) t -> 'a key -> 'b

find_exn t k returns the current binding of k in t, or raises Not_found if no such binding exists.

val find_and_call : ('a, 'b) t -> 'a key -> if_found:('b -> 'c) -> if_not_found:('a key -> 'c) -> 'c

find_and_call t k ~if_found ~if_not_found

is equivalent to:

match find t k with Some v -> if_found v | None -> if_not_found k

except that it doesn't allocate the option.

val find_and_remove : ('a, 'b) t -> 'a key -> 'b option

find_and_remove t k returns Some (the current binding) of k in t and removes it, or None is no such binding exists

val merge : ('c, ('k, 'a) t -> ('k, 'b) t -> f:(key:'k key -> [
| `Left of 'a
| `Right of 'b
| `Both of 'a * 'b
] -> 'c option) -> ('k, 'c) t) map_options

Merge two hashtables.

The result of merge f h1 h2 has as keys the set of all k in the union of the sets of keys of h1 and h2 for which d(k) is not None, where:

d(k) =

  • f ~key:k (Some d1) None if k in h1 is to d1, and h2 does not map k;
  • f ~key:k None (Some d2) if k in h2 is to d2, and h1 does not map k;
  • f ~key:k (Some d1) (Some d2) otherwise, where k in h1 is to d1 and k in h2 is to d2.

Each key k is mapped to a single piece of data x, where d(k) = Some x.

val merge_into : f:(key:'a key -> 'b -> 'c option -> 'c option) -> src:('a, 'b) t -> dst:('a, 'c) t -> unit

Merge one hashtable into another.

After merge_into f src dst, for every key in src, key will be re-mapped in dst to v if f ~key d1 (find dst key) = Some v.

val keys : ('a, _) t -> 'a key list

Returns the list of all keys for given hashtable.

Returns the list of all data for given hashtable.

val data : (_, 'b) t -> 'b list

Returns the list of all data for given hashtable.

val filter_inplace : (_, 'b) t -> f:('b -> bool) -> unit

filter_inplace t ~f removes all the elements from t that don't satisfy f.

val filteri_inplace : ('a, 'b) t -> f:(key:'a key -> data:'b -> bool) -> unit
val filter_keys_inplace : ('a, _) t -> f:('a key -> bool) -> unit

replace_all t ~f applies f to all elements in t, transforming them in place

val replace_all : (_, 'b) t -> f:('b -> 'b) -> unit

replace_all t ~f applies f to all elements in t, transforming them in place

val replace_alli : ('a, 'b) t -> f:(key:'a key -> data:'b -> 'b) -> unit

filter_replace_all combines the effects of replace_all and filter_inplace

val filter_replace_all : (_, 'b) t -> f:('b -> 'b option) -> unit

filter_replace_all combines the effects of replace_all and filter_inplace

val filter_replace_alli : ('a, 'b) t -> f:(key:'a key -> data:'b -> 'b option) -> unit
val equal : ('a, 'b) t -> ('a, 'b) t -> ('b -> 'b -> bool) -> bool

equal t1 t2 f and similar t1 t2 f both return true iff t1 and t2 have the same keys and for all keys k, f (find_exn t1 k) (find_exn t2 k). equal and similar only differ in their types.

val similar : ('a, 'b1) t -> ('a, 'b2) t -> ('b1 -> 'b2 -> bool) -> bool
val to_alist : ('a, 'b) t -> ('a key * 'b) list

Returns the list of all (key,data) pairs for given hashtable.
