val map : (elt -> elt) -> t -> t
val is_singleton : t -> bool
val choose_one : t -> elt

Returns one element, assuming the set is a singleton. Raises Not_found on an empty set, Failure on a non-singleton.

val choose_opt : t -> elt option
val of_list : elt list -> t
val to_string : t -> string
val to_json : t -> OpamJson.t
val of_json : OpamJson.t -> t option
val find : (elt -> bool) -> t -> elt
val find_opt : (elt -> bool) -> t -> elt option
val safe_add : elt -> t -> t

Raises Failure in case the element is already present

val fixpoint : (elt -> t) -> t -> t

Accumulates the resulting sets of a function of elements until a fixpoint is reached

val map_reduce : ?default:'a -> (elt -> 'a) -> ('a -> 'a -> 'a) -> t -> 'a

map_reduce f op t applies f to every element of t and combines the results using associative operator op. Raises Invalid_argument on an empty set, or returns default if it is defined.
