Module `CCPair`Source

Tuple Functions

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

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

Make a tuple from its components.

since 0.16

Sourceval map1 : ('a -> 'b) -> ('a * 'c) -> 'b * 'c

map1 f (x, y) returns (f x, y).

Sourceval map2 : ('a -> 'b) -> ('c * 'a) -> 'c * 'b

map2 f (x, y) returns (x, f y).

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

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

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

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

Sourceval map_fst : ('a -> 'b) -> ('a * _) -> 'b

Compose the given function with fst.

since 0.3.3

Sourceval map_snd : ('a -> 'b) -> (_ * 'a) -> 'b

Compose the given function with snd.

since 0.3.3

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

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

Swap the components of the tuple.

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

Map on the left side of the tuple.

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

Map on the right side of the tuple.

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

Map on both sides of a tuple.

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

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

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

Uncurrying (merges the two components of a tuple).

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

Synonym to merge.

since 0.3.3

Sourceval dup : 'a -> 'a * 'a

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

since 0.3.3

Sourceval 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) ->

Source

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

  int

Source

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

Print tuple in a string

since 2.7

Sourcetype 'a printer = Format.formatter -> 'a -> unit

Sourceval pp : ?sep:string -> 'a printer -> 'b printer -> ('a * 'b) printer

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