Bi_mappable_types.Basic0
Basic0 is the basic signature of an arity-0 bi-mappable type.
Basic0
Functions mapped over arity-0 types must preserve both element types.
include Generic_types.Bi0
type t
Fixed type of containers.
type left
Fixed type of left elements.
type right
Fixed type of right elements.

val bi_map : t -> left:(left -> left) -> right:(right -> right) -> t
bi_map c ~left ~right maps left over every 'l1 left, and right over every 'r1 right, in c.
