type ('l, 'r) t

Generic container type.

type 'l left

Generic left type.

type 'r right

Generic right type.

val bi_map : ('l1, 'r1) t -> left:('l1 left -> 'l2 left) -> right:('r1 right -> 'r2 right) -> ('l2, 'r2) t

bi_map c ~left ~right maps left over every 'l1 left, and right over every 'r1 right, in c.

val map_left : ('l1, 'r) t -> f:('l1 left -> 'l2 left) -> ('l2, 'r) t

map_left c ~f maps f over the left type of c only.

val map_right : ('l, 'r1) t -> f:('r1 right -> 'r2 right) -> ('l, 'r2) t

map_right c ~f maps f over the right type of c only.
