module ActiveSupport::CompareWithRange

Extends the default Range#=== to support range comparisons.

(1..5) === (1..5)  # => true
(1..5) === (2..3)  # => true
(1..5) === (1...6) # => true
(1..5) === (2..6)  # => false

The native Range#=== behavior is untouched.

('a'..'f') === ('c') # => true
(5..9) === (11) # => false

The given range must be fully bounded, with both start and end.

# File activesupport/lib/active_support/core_ext/range/compare_range.rb, line 16
def ===(value)
  if value.is_a?(::Range)
    cover?(value)
  else
    super
  end
end

Extends the default Range#include? to support range comparisons.

(1..5).include?(1..5)  # => true
(1..5).include?(2..3)  # => true
(1..5).include?(1...6) # => true
(1..5).include?(2..6)  # => false

The native Range#include? behavior is untouched.

('a'..'f').include?('c') # => true
(5..9).include?(11) # => false

The given range must be fully bounded, with both start and end.

# File activesupport/lib/active_support/core_ext/range/compare_range.rb, line 35
def include?(value)
  if value.is_a?(::Range)
