Let's talk about Python and Rust. I used to do a lot more Python than I do now, but I still love it for its beauty.

One of the first things I was missing in Rust when coming from Python were List Comprehensions. It took me a while to figure out, that the Rust way - using iter(), filter(), and map() - actually is a better fit for the language. I want to show you how to port Rust list comprehensions to Rust.

Keywords

iterators, map, filter, Entry API, List comprehensions

Things I mentioned during the show

• Reading files using the Rust Cookbook.
• DevDocs is a nice Rust documentation viewer. Also supports a ton of other languages and works offline.

Things I should have mentioned (but forgot)

• Iteration patterns for Result & Option
• Experimenting with Python is much cooler with Jupyter (or IPython) notebooks. I've added an example to the code section.
• If you really need list comprehensions, you could use cute, which is a set of macros that make this syntax possible.
