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

left l is Left l

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

right r is Right r

val is_left : ( 'a, 'b ) t -> bool

is_left x checks if x = Left _

val is_right : ( 'a, 'b ) t -> bool

is_right x checks if x = Right _

val find_left : ( 'a, 'b ) t -> 'a option

find_left x returns l if x = Left l and None otherwise.

val find_right : ( 'a, 'b ) t -> 'b option

find_right x returns r if x = Left r and None otherwise.

val map_left : ( 'a1 -> 'a2 ) -> ( 'a1, 'b ) t -> ( 'a2, 'b ) t

Map of the Left variant.

val map_right : ( 'b1 -> 'b2 ) -> ( 'a, 'b1 ) t -> ( 'a, 'b2 ) t

Map of the Right variant.

val map : 
  left:( 'a1 -> 'a2 ) ->
  right:( 'b1 -> 'b2 ) ->
  ( 'a1, 'b1 ) t ->
  ( 'a2, 'b2 ) t

Map using left or right.

val fold : left:( 'a -> 'c ) -> right:( 'b -> 'c ) -> ( 'a, 'b ) t -> 'c

Fold using left or right.

val iter : left:( 'a -> unit ) -> right:( 'b -> unit ) -> ( 'a, 'b ) t -> unit

Iter using left or right.

val for_all : 
  left:( 'a -> bool ) ->
  right:( 'b -> bool ) ->
  ( 'a, 'b ) t ->
  bool

Check some property on Left or Right variant.
