Sourcetype key

Sourcetype +'a t

Sourceval empty : 'a t

Sourceval is_empty : _ t -> bool

Sourceval singleton : key -> 'a -> 'a t

Sourceval mem : key -> _ t -> bool

Sourceval get : key -> 'a t -> 'a option

Sourceval get_exn : key -> 'a t -> 'a

raises Not_found
if the key is not present.

Sourceval nth : int -> 'a t -> (key * 'a) option

nth i m returns the i-th key, value in the ascending order. Complexity is O(log (cardinal m)).

Sourceval nth_exn : int -> 'a t -> key * 'a

raises Not_found
if the index is invalid.

Sourceval get_rank : key -> 'a t -> [ `At of int | `After of int | `First ]

get_rank k m looks for the rank of k in m, i.e. the index of k in the sorted list of bindings of m. let (`At n) = get_rank k m in nth_exn n m = get m k should hold.

Sourceval add : key -> 'a -> 'a t -> 'a t

Sourceval remove : key -> 'a t -> 'a t

Sourceval update : key -> ('a option -> 'a option) -> 'a t -> 'a t

update k f m calls f (Some v) if get k m = Some v, f None otherwise. Then, if f returns Some v' it binds k to v', if f returns None it removes k.

Sourceval cardinal : _ t -> int

Sourceval weight : _ t -> int

Sourceval fold : f:('b -> key -> 'a -> 'b) -> x:'b -> 'a t -> 'b

Sourceval mapi : f:(key -> 'a -> 'b) -> 'a t -> 'b t

Map values, giving both key and value. Will use WORD.of_list to rebuild keys.

since 0.17

Sourceval map : f:('a -> 'b) -> 'a t -> 'b t

Map values, giving only the value.

since 0.17

Sourceval iter : f:(key -> 'a -> unit) -> 'a t -> unit

Sourceval split : key -> 'a t -> 'a t * 'a option * 'a t

split k t returns l, o, r where l is the part of the map with keys smaller than k, r has keys bigger than k, and o = Some v if k, v belonged to the map.

val merge : 
  f:(key -> 'a option -> 'b option -> 'c option) ->
  'a t ->
  'b t ->
  'c t

Like Map.S.merge.

Sourceval extract_min : 'a t -> key * 'a * 'a t

extract_min m returns k, v, m' where k,v is the pair with the smallest key in m, and m' does not contain k.

raises Not_found
if the map is empty.

Sourceval extract_max : 'a t -> key * 'a * 'a t

extract_max m returns k, v, m' where k,v is the pair with the highest key in m, and m' does not contain k.

raises Not_found
if the map is empty.

Sourceval choose : 'a t -> (key * 'a) option

Sourceval choose_exn : 'a t -> key * 'a

raises Not_found
if the tree is empty.

Sourceval random_choose : Random.State.t -> 'a t -> key * 'a

Randomly choose a (key,value) pair within the tree, using weights as probability weights.

raises Not_found
if the tree is empty.

Sourceval add_list : 'a t -> (key * 'a) list -> 'a t

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

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

Sourceval add_iter : 'a t -> (key * 'a) iter -> 'a t

Sourceval of_iter : (key * 'a) iter -> 'a t

Sourceval to_iter : 'a t -> (key * 'a) iter

Sourceval add_gen : 'a t -> (key * 'a) gen -> 'a t

Sourceval of_gen : (key * 'a) gen -> 'a t

Sourceval to_gen : 'a t -> (key * 'a) gen
