Module BatTuple.Tuple2

module Tuple2: sig .. end

Pairs. Some of the functions here are also exposed in Pervasives, as documented below.

type ('a, 'b) t = 'a * 'b 
val make : 'a -> 'b -> 'a * 'b
val first : 'a * 'b -> 'a

Equivalent to Pervasives.fst.

val second : 'a * 'b -> 'b

Equivalent to Pervasives.snd.

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

Equivalent to BatPervasives.

.

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

Like BatTuple.Tuple2.map but specialized for tuples with elements of the same type.

mapn f is equivalent to map f f.

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

map1 f (x,y) returns (f x,y)

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

map2 f (x,y) returns (x,f y)
