val left_list : t -> Alias.t list

Get the left side of a functional dependency as a list (i.e. left of X -> Y returns Y)

val right : t -> Alias.Set.t

Get the right side of a functional dependency (i.e. left of X -> Y returns Y)

val right_list : t -> Alias.t list

Get the right side of a functional dependency as a list (i.e. left of X -> Y returns Y)

val all_columns : t -> Alias.Set.t

Get all of the columns of a functional dependency (i.e. left of X -> Y returns XY)

val all_columns_list : t -> Alias.t list

Get all of the columns of a functional dependency as a list (i.e. left of X -> Y returns XY)

val of_lists : (Alias.t list * Alias.t list) -> t

Convert two sets of alias lists into a functional dependency

val key_fd : keys:Alias.t list -> cols:Alias.t list -> t
