   This functionality has been moved to <a href="../../dry-core">dry-core</a>, with an identical API.
   To update, change your code to <code>Dry::Core::Equalizer</code> and `require 'dry/core/equalizer'`.

-
-`dry-equalizer` was a simple mixin that can be used to add instance variable based equality, equivalence and inspection methods to your objects.
-
-### Usage
-
-```ruby
-require 'dry/core/equalizer'
-
-class GeoLocation
-  include Dry::Core::Equalizer(:latitude, :longitude)
-
-  attr_reader :latitude, :longitude
-
-  def initialize(latitude, longitude)
-    @latitude, @longitude = latitude, longitude
-  end
-end
-
-point_a = GeoLocation.new(1, 2)
-point_b = GeoLocation.new(1, 2)
-point_c = GeoLocation.new(2, 2)
-
-point_a.inspect    # => "#<GeoLocation latitude=1 longitude=2>"
-
-point_a == point_b           # => true
-point_a.hash == point_b.hash # => true
-point_a.eql?(point_b)        # => true
-point_a.equal?(point_b)      # => false
-
-point_a == point_c           # => false
-point_a.hash == point_c.hash # => false
-point_a.eql?(point_c)        # => false
-point_a.equal?(point_c)      # => false
-```
-
-### Configuration options
-
-#### `inspect`
-
-Use `inspect` option to skip `#inspect` method overloading:
-
-```ruby
-class Foo
-  include Dry::Core::Equalizer(:a, inspect: false)
-
-  attr_reader :a, :b
-
-  def initialize(a, b)
-    @a, @b = a, b
-  end
-end
-
-Foo.new(1, 2).inspect
-# => "#<Foo:0x00007fbc9c0487f0 @a=1, @b=2>"
-```
-
-#### `immutable`
-
-For objects that are immutable it doesn't make sense to calculate `#hash` every time it's called. To memoize hash use `immutable` option:
-
-```ruby
-class ImmutableHash
-  include Dry::Core::Equalizer(:foo, :bar, immutable: true)
-
-
-  attr_accessor :foo, :bar
-
-  def initialize(foo, bar)
-    @foo, @bar = foo, bar
-  end
-end
-
-obj = ImmutableHash.new('foo', 'bar')
-old_hash = obj.hash
-obj.foo = 'changed'
-old_hash == obj.hash
-# => true
-```
