Set

ruby/spec describes 60 methods in core/set, and Metorex implements 59 of them. The parameters are what Method#parameters answers under Metorex.

Enumerable#

Enumerable#to_set: implemented, parameters [[:rest, :args], [:block, :block]]. Makes a set from the enumerable object with given arguments. An example calling it.

Set#

Set#&: implemented, parameters [[:req]]. Returns a new set containing elements common to the set and the given enumerable object.
Set#+: implemented, parameters [[:req]]. Returns a new set built by merging the set and the elements of the given enumerable object.
Set#-: implemented, parameters [[:req]]. Returns a new set built by duplicating the set, removing every element that appears in the given enumerable object.
Set#<: implemented, parameters [[:req]]. Returns true if the set is a proper subset of the given set.
Set#<<: implemented, parameters [[:req]]. Adds the given object to the set and returns self.
Set#<=: implemented, parameters [[:req]]. Returns true if the set is a subset of the given set.
Set#<=>: implemented, parameters [[:req]]. Returns 0 if the set are equal, -1 / 1 if the set is a proper subset / superset of the given set, or nil if they both have unique elements.
Set#==: implemented, parameters [[:req]]. Returns true if two sets are equal.
Set#===: implemented, parameters [[:req]]. Returns true if the set contains the given object:
Set#>: implemented, parameters [[:req]]. Returns true if the set is a proper superset of the given set.

Set#disjoint?: implemented, parameters [[:req]]. Returns true if the set and the given enumerable have no element in common. An example calling it.
Set#divide: implemented, parameters [[:block, :block]]. Divides the set into a set of subsets according to the commonality defined by the given block. An example calling it.
Set#each: implemented, parameters []. Calls the given block once for each element in the set, passing the element as parameter. An example calling it.

Set#eql?: implemented, parameters [[:req]]. Returns true if two sets are equal. An example calling it.
Set#filter!: implemented, parameters []. Equivalent to Set#keep_if, but returns nil if no changes were made.
Set#flatten: implemented, parameters []. Returns a new set that is a copy of the set, flattening each containing set recursively. An example calling it.
Set#flatten!: implemented, parameters []. Equivalent to Set#flatten, but replaces the receiver with the result in place. An example calling it.
Set#flatten_merge: not implemented.
Set#hash: implemented, parameters []. Returns hash code for set. An example calling it.
Set#include?: implemented, parameters [[:req]]. Returns true if the set contains the given object: An example calling it.
Set#initialize: implemented, parameters [[:opt, :enumerable], [:block, :block]]. An example calling it.
Set#initialize_clone: implemented, parameters [[:rest]].
Set#inspect: implemented, parameters []. Returns a new string containing the set entries: An example calling it.
Set#intersect?: implemented, parameters [[:req]]. Returns true if the set and the given enumerable have at least one element in common. An example calling it.
Set#intersection: implemented, parameters [[:req]]. Returns a new set containing elements common to the set and the given enumerable object. An example calling it.
Set#join: implemented, parameters [[:rest]]. Returns a string created by converting each element of the set to a string. An example calling it.
