Title: Hands-On Rust (Chapter 11)
When I reached the code *dist < &std::f32::MAX, I had to stop a second to remember what that was about.
I changed my code to add
const UNREACHABLE: i32 = std::i32::MAX;
and could then change the expression to *dist != &UNREACHABLE. (I know you don’t generally use == or != with floats, but I think it works here (guess I’ll find out)
