Level Up your Rust pattern matching

I really like rust's pattern matching and it's the feature I miss the most in other languages. However, I feel like its easy to encode too much control flow in one match statement and make a garbled mess. The first example in the article uses all the features (destructuring, @ sigil, inline if, etc.) which I think makes it unreadable.
Overall good article, but those large match statements are difficult to read.
The first pattern-matching language I used was Erlang. I generally like Rust's just as much, but Erlang/Elixir's binary-matching syntax was awesome and is sorely missed:

I needed this. I have some level of intuitive understanding, but this reference will be great whenever I'm not quite sure if something is possible or not.
Suggest for improvement: If you link a Rust playground, at least make it compilable.
