Method: Weak::Set#|

Defined in:
lib/weak/set.rb

#|(enum) ⇒ Weak::Set Also known as: +, union

Note:

Weak::Set does not test member equality with ‘==` or `eql?`. Instead, it always checks strict object equality, so that, e.g., different strings are not considered equal, even if they may contain the same string content.

Returns a new weak set built by merging ‘self` and the elements of the given enumerable object.

Examples:

Weak::Set[1, 2, 3] | Weak::Set[2, 4, 5] # => #<Weak::Set {1, 2, 3, 4, 5}>
Weak::Set[1, 3, :z] | (1..4)            # => #<Weak::Set {1, 3, :z, 2, 4}>

Parameters:

Returns:

  • (Weak::Set) —

    a new weak set built by merging ‘self` and the elements of the given enumerable object.
