Method: Range#eql?

Defined in:

range.c

#eql?(other) ⇒ Boolean

Returns true if and only if:

• other is a range.

• other.begin.eql?(self.begin).

• other.end.eql?(self.end).

• other.exclude_end? == self.exclude_end?.

Otherwise returns false.

r = (1..5)
r.eql?(1..5)                  # => true
r = Range.new(1, 5)
r.eql?('foo')                 # => false
r.eql?(2..5)                  # => false
r.eql?(1..4)                  # => false
r.eql?(1...5)                 # => false
r.eql?(Range.new(1, 5, true)) # => false

Note that even with the same argument, the return values of #== and #eql? can differ:

(1..2) == (1..2.0)   # => true
(1..2).eql? (1..2.0) # => false
