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 map1 : ('a -> 'b) -> 'a * 'c -> 'b * 'c
val map2 : ('a -> 'b) -> 'c * 'a -> 'c * 'b
val map : ('a -> 'c) -> ('b -> 'd) -> 'a * 'b -> 'c * 'd
val map_same : ('a -> 'b) -> 'a * 'a -> 'b * 'b
val map_fst : ('a -> 'b) -> 'a * 'c -> 'b
Compose the given function with fst.
Since 0.3.3
val map_snd : ('a -> 'b) -> 'c * 'a -> 'b
Compose the given function with snd.
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
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
type 'a printer = Format.formatter -> 'a -> unit
val pp : ?sep:string ->
'a printer -> 'b printer -> ('a * 'b) printer
