As critical as I have become of big tech, I readily admit to using Claude Code to help me learn new things. But sometimes I just don't get it.

I have always had difficulty with functional programing patterns - I tried Scala but I never got the hang of it - but this seems to be a closure pattern in Rust (been reading https://doc.rust-lang.org/book/ch13-01-closures.html) but it's just a blind spot I have.

Looking for a good ELI5 source to help me understand this. Tips?
