FastStruct : A fast implementation of OpenStruct

Install

gem install fast_struct

Usage

    require 'fast_struct'
    s = FastStruct.new(:foo => 1)
    s[:bar] = 2
    s.baz = 3

    p s.foo, s[:foo], s.to_hash

Features

1. Speed
2. Deep wrapping
3. Hash-type access (s[:bar] as well as s.bar)
4. Mutability (s[:baz] = "x")

Benchmark
