module MakeDefault (X : Hashtbl.HashedType) : DEFAULT with type key = X.t
type
type 'a t
A hashtable for keys of type key and values of type 'a
val create : ?size:int -> 'a -> 'a t
create d makes a new table that maps every key to d by default.
size : optional size of the initial table
val create_with : ?size:int -> (key -> 'a) -> 'a t
Similar to create d but here d is a function called to obtain a
new default value for each distinct key. Useful if the default
value is stateful.
val get : 'a t -> key -> 'a
Unfailing retrieval (possibly returns the default value). This will
modify the table if the key wasn't present.
val set : 'a t -> key -> 'a -> unit
Replace the current binding for this key
val remove : 'a t -> key -> unit
Remove the binding for this key. If get tbl k is called later, the
default value for the table will be returned
val to_seq : 'a t -> (key * 'a) CCHashtbl.sequence
Pairs of (elem, value) for all elements on which get was called
