struct Set(T)

• Set(T)
• Struct
• Value
• Object

Overview

Set implements a collection of unordered values with no duplicates.

An Enumerable object can be converted to Set using the #to_set method.

Set uses Hash as storage, so you must note the following points:

• Equality of elements is determined according to Object#== and Object#hash.
• Set assumes that the identity of each element does not change while it is stored. Modifying an element of a set will render the set to an unreliable state.

Example

s1 = Set{1, 2}
s2 = [1, 2].to_set
s3 = Set.new [1, 2]
s1 == s2 # => true
s1 == s3 # => true
s1.add(2)
s1.concat([6, 8])
s1.subset_of? s2 # => false
s2.subset_of? s1 # => true
