This is an upstream issue with https://github.com/azerupi/mdBook , you should file a bug!
That was really well written. As I was reading through the example code in the section about closures let add_one = |x| x + 1; let five = add_one(4); I thought to myself "hmm I wonder what happens if I were to call the code with a float rather than an int?" Answered my question a few paragraphs down. Kudos. Is it possible to write a generic closure? i.e something that would add 1 to any numeric type.
The whole new Rust Book is quite well written. It was my first resource when I read it a few months ago and I found it easy to understand everything it covered - even lifetimes which I completely failed to get from the original book or other online resources. I look forward to the rest of the chapters being filled in.
