Method: Weak::Set#proper_superset?

Defined in:
lib/weak/set.rb

#proper_superset?(other) ⇒ Bool Also known as: >

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.

Parameters:

Returns:

  • (Bool) —

    true if self is a proper superset of the given set, false otherwise
