Method: Weak::Set#==

Defined in:
lib/weak/set.rb

#==(other) ⇒ Bool

Returns true if two weak sets are equal. The equality of each couple of elements is defined according to strict object equality so that, e.g., different strings are not equal, even if they may contain the same data.

Examples:

Weak::Set[1, 2] == Weak::Set[2, 1]         #=> true
Weak::Set[1, 3, 5] == Weak::Set[1, 5]      #=> false
Weak::Set[1, 2, 3] == [1, 3, 2]            #=> false

Parameters:

  • other (Weak::Set) —

    a weak set to compare to self

Returns:

  • (Bool) —

    true if the other object is a weak set containing exactly the same elements as self, false otherwise
