Safe version of Hashtbl.find

val keys : 'a t -> key sequence

Iterate on keys (similar order as Hashtbl.iter)

val values : 'a t -> 'a sequence

Iterate on values in the table

val keys_list : ('a, 'b) Hashtbl.t -> 'a list

keys t is the list of keys in t.

  • since 0.8
val values_list : ('a, 'b) Hashtbl.t -> 'b list

values t is the list of values in t.

  • since 0.8
val map_list : (key -> 'a -> 'b) -> 'a t -> 'b list

Map on a hashtable's items, collect into a list

val to_seq : 'a t -> (key * 'a) sequence

Iterate on values in the table

val of_seq : (key * 'a) sequence -> 'a t

From the given bindings, added in order

val to_list : 'a t -> (key * 'a) list

List of bindings (order unspecified)

val of_list : (key * 'a) list -> 'a t
