Tuple Functions

type ('a, 'b) t = 'a * 'b

val make : 'a -> 'b -> ('a, 'b) t

Make a tuple from its components.

since 0.16

val map_fst : ('a -> 'b) -> ('a * 'c) -> 'b * 'c

map_fst f (x, y) returns (f x, y). Renamed from map1 since 3.0.

val map_snd : ('a -> 'b) -> ('c * 'a) -> 'c * 'b

map_snd f (x, y) returns (x, f y). Renamed from map2 since 3.0.

val map : ('a -> 'c) -> ('b -> 'd) -> ('a * 'b) -> 'c * 'd

Synonym to (***). Map on both sides of a tuple.

val map_same : ('a -> 'b) -> ('a * 'a) -> 'b * 'b

Like map but specialized for pairs with elements of the same type.

val map2 : 
  ('a1 -> 'b1 -> 'c1) ->
  ('a2 -> 'b2 -> 'c2) ->
  ('a1 * 'a2) ->
  ('b1 * 'b2) ->
  'c1 * 'c2

map2 f g (a,b) (x,y) return (f a x, g b y).

since 3.0

val map_same2 : ('a -> 'b -> 'c) -> ('a * 'a) -> ('b * 'b) -> 'c * 'c

map_same2 f (a,b) (x,y) return (f a x, f b y).

since 3.0

val fst_map : ('a -> 'b) -> ('a * _) -> 'b

Compose the given function with fst. Rename from map_fst since 3.0.

since 0.3.3

val snd_map : ('a -> 'b) -> (_ * 'a) -> 'b

Compose the given function with snd. Rename from map_snd since 3.0.

since 0.3.3

val iter : ('a -> 'b -> unit) -> ('a * 'b) -> unit

val swap : ('a * 'b) -> 'b * 'a

Swap the components of the tuple.

val (<<<) : ('a -> 'b) -> ('a * 'c) -> 'b * 'c

Map on the left side of the tuple.

val (>>>) : ('a -> 'b) -> ('c * 'a) -> 'c * 'b

Map on the right side of the tuple.

val (***) : ('a -> 'c) -> ('b -> 'd) -> ('a * 'b) -> 'c * 'd

Map on both sides of a tuple.

val (&&&) : ('a -> 'b) -> ('a -> 'c) -> 'a -> 'b * 'c

f &&& g is fun x -> f x, g x. It splits the computations into two parts.

val merge : ('a -> 'b -> 'c) -> ('a * 'b) -> 'c

Uncurrying (merges the two components of a tuple).

val fold : ('a -> 'b -> 'c) -> ('a * 'b) -> 'c

Synonym to merge.

since 0.3.3

val dup : 'a -> 'a * 'a

dup x = (x,x) (duplicate the value).

since 0.3.3

val dup_map : ('a -> 'b) -> 'a -> 'a * 'b

dup_map f x = (x, f x). Duplicates the value and applies the function to the second copy.

since 0.3.3

val equal : 
  ('a -> 'a -> bool) ->
  ('b -> 'b -> bool) ->
  ('a * 'b) ->
  ('a * 'b) ->
  bool

val compare : 
  ('a -> 'a -> int) ->
  ('b -> 'b -> int) ->
  ('a * 'b) ->
  ('a * 'b) ->
  int

val to_string : 
  ?sep:string ->
  ('a -> string) ->
  ('b -> string) ->
  ('a * 'b) ->
  string

Print tuple in a string

since 2.7

type 'a printer = Stdlib.Format.formatter -> 'a -> unit

val pp : 
  ?pp_start:unit printer ->
  ?pp_stop:unit printer ->
  ?pp_sep:unit printer ->
  'a printer ->
  'b printer ->
  ('a * 'b) printer

Print a pair given an optional separator, an optional start and stop and a method for printing each of its elements.
