val empty : 'a t

empty returns the empty table

val add : ?overwrite:bool -> key -> 'a -> 'a t -> 'a t

add k v t modifies the table t to add the element v at key k. The optional value overwrite is set to false by default. When set to false, the add function raises an exception Conflict when the key k was already associated with some value. When set to true, the add function does not raise Conflict if some value was already associated to the key

val find : key -> 'a t -> 'a

find k t returns the element associated with the key k in t. Raises Not_found if no such element exists

val fold : (key -> 'a -> 'b -> 'b) -> 'b -> 'a t -> 'b

fold f a t returns f kn vn (f kn-1 vn-1 (...(f k1 v1 a) ...)) where the ki and vi are the associated values in t. The elements are listed in order wrt. to the key

val iter : (key -> 'a -> unit) -> 'a t -> unit

fold f a t returns f kn vn (f kn-1 vn-1 (...(f k1 v1 a) ...)) where the ki and vi are the associated values in t. The elements are listed in order wrt. to the key

val pp : ?sep: ((Format.formatter -> (key * 'a) -> unit) -> (key * 'a) -> unit, Format.formatter, unit, unit, unit, (Format.formatter -> (key * 'a) -> unit) -> (key * 'a) -> unit) format6 -> (Format.formatter -> key -> 'a -> unit) -> Format.formatter -> 'a t -> unit
