Ruby to Rust Cheat Sheet

The goal of this is to have an easily-scannable reference for the most common syntax idioms in Ruby and Rust so that programmers most comfortable with Ruby can quickly get through the syntax differences and feel like they could read and write basic Rust programs.

What do you think? Does this meet its goal? If not, why not?

Variables

Ruby:

# This algorithm takes a *sorted* list of integers, probably record
# IDs and compresses them into a series of ranges. It also includes a
# verification check that no values were lost.

def compress(ary)
  range_start = ary.first
  compressed = []

  ary.each_with_index do |value, index|
    # TODO: This could skip indices that have already been considered.

First, you install ruby-build and chruby. ruby-build is a program that knows how to download and build different ruby versions. chruby manages $PATH to control which ruby gets invoked in your shell. They work completely independently.

sudo su
cd /usr/src

git clone https://github.com/sstephenson/ruby-build.git
cd ruby-build
./install.sh
cd -

module NestedException

  # Public: Initializes a new nested error, the original error defaults
  # to the global error variable so that it doesn't need to be explicity
  # provided when re-raising an exception.
  def initialize(message = nil, cause = $!)
    @cause = cause
    super(message || cause && cause.message)
  end
