# Obj [![Build Status](https://travis-ci.org/svenfuchs/obj.svg?branch=master)](https://travis-ci.org/svenfuchs/obj)

A Struct replacement that allows default arguments, and omits the

hash-style API that Struct implements.

## Installation

```

gem install ruby-obj

```

## Usage

```ruby

require 'obj'

class One < Obj.new(:one, two: :default)

end

obj = One.new(1)

obj.one  # => 1

obj.one? # => true

obj.two  # => :default

obj.two? # => true

obj = One.new(nil)

obj.one? # => false

```

Modules included to `Obj` are propagated to all instances:

```ruby

module Foo

  def foo

  end

end

Obj.include(Foo)

class One < Obj.new(:one)

end

one = One.new(1)

one.respond_to?(:foo) # => true

```

# Benchmark

`Obj` is marginally slower than `Struct` (which is implemented in C):

```ruby

require 'benchmark'

require 'obj'

n = 1_000_000

str = Struct.new(:foo)

obj = Obj.new(:foo)

Benchmark.bm(10) do |b|

  b.report('str:') { n.times { str.new(:foo).foo } }

  b.report('obj:') { n.times { obj.new(:foo).foo } }

end

```

```

                 user     system      total        real

str:         0.180000   0.000000   0.180000 (  0.174254)

obj:         0.180000   0.000000   0.180000 (  0.181985)

```
