For example you don't check that a string *can* parse (validate) but then then pass the string version to the next function. You transform from string to number (parse) and pass that. Now child functions can be simpler because they don't have to worry about re-validating. — PolitiTweet.org

I loved this whole talk from (a new embedded OS in Rust), but I really feel changed by the "parse don't validate" concept he explains around the 27:30 mark https://t.co/FGJal6XcQv — PolitiTweet.org

This sounds kind of obvious in the string to number case, but I think there are a lot of places in my code where I get a big object, check one truth about it, but then pass it along unchanged. I want to watch out for that. — PolitiTweet.org
