Crust of Rust: functions, closures, and their traits

In this episode, we go over the differences between function items, function pointers, and closures, as well as how they interact with the Fn* traits. We also touch upon dynamically dispatched Fns and experimental const Fn bounds.

I've spliced out some audio issues that occurred on the live-stream, but hopefully it won't be too noticeable :p

I might not have the most experience in the world but I've gone through 5 programming languages that I feel somewhat comfortable in, along with all their ecosystem, communities, documentations, tutorials etc. Just wanted to say you sir are making the best programming learning resources I've seen so far. You are truely gifted, thank you so much for sharing your knowledge. Cheers from Poland.

Jon - Thanks so much for this instructive video. Clearly, the rich and challenging concepts you demonstrate in Rust require careful consideration and exploration before use. Closures are still a challenge to fully comprehend, not because you video lacked anything, but simply because the Rust idiom requies one to carefully design the program's call flow. As an aside, would you be willing to share your .vimrc file and the plug-ins you are using?

Great video, since I came from C ++ to Rust, it's just great for me to see videos like this at this quality level! I have a suggestion for a possible future video: Since Rust has no inheritance like many languages like Java / C ++, you could possibly make a video showing how object-oriented solutions are made differently in Rust, that would be interesting

Rust and the teaching tools around it have finally helped me escape the "writing bad, unflexible scripts" stage of my programming career. Thanks Jon for all your incredible videos! Can't wait to check out your book.

Jon , thank you so much for resources that you have been sharing for free for the Rust community or anyone interested. Your contents pulled me to Rust and am investigating time to learn it better.

I was JUST the other day wishing you had a video on closures 😂

Preordered the book. I already know I will get $25 worth of value. I already get that with the YouTube channel!
