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:

styd

#!/usr/bin/env ruby
class String
  def palindrome?(strict = false)
    return true if length.zero? || length == 1
    i = -1
    j = length
    length.times do
      loop do
        i += 1
        break if strict || self[i] =~ /[A-z0-9]/
