HyperIterator-Rails

This gem is a Rails adapter for the hyper_iterator gem. Before you start using this, please read the docs of hyper_iterator!

Installation

Add this line to your application's Gemfile:

gem 'hyper_iterator-rails'

And then execute:

$ bundle

Or install it yourself as:

$ gem install hyper_iterator

Available Methods (adding more)

For Array

• each_slice!
• each!
• HyperIterator.each!: This is the same as each!. But it takes an array as argument. This is added because there are gems that implement their own each method (e.g. the pg gem). Instead of monkey patching all the gems out there, this is a compromise for flexibility.

For Result from ActiveRecord Query

users = User.where(...)
users.each! { |user| ... }

# each_slice! is not available yet.

Gotcha

These methods work just as the non bang version, except that, it WILL MUTATE the original array by REMOVING ALL the elements from it.

arr = (1..10).to_a
arr.each! { |el| ... }
# After the iteration, the arr is empty!
# arr => []
