I saw your Stack overflow question. I wanted to know, did you ever get it working in Rust before you switched it to Go?

https://stackoverflow.com/questions/41490202/how-can-i-create-a-struct-with-a-hashmap-where-the-keys-the-same-type-as-the-con?rq=1

I am on Chapter 2 and ran into what looks similar or related to your issue.

...
#[derive(Debug, Hash, Eq, PartialEq)]
pub struct Cell {
    row: u32,
    col: u32,
    links: HashMap<String,bool>,
}
...

but I get this error
the trait std::hash::Hash is not implemented for std::collections::HashMap<std::boxed::Box<maze::Cell>, bool>
