Chapter 7.4 The part about "pub use" doesn't make isn't right

[rempas]

I'm talking about this part. In the book it talks about how use is local to a scope and not to a module. I'm just learning Rust and I couldn't find how this applies so I made my research and found out about the reference book that talks about use visibility being local to a module and nowhere the word scope appears. The example in the book also doesn't make any sense while the example in the reference book makes absolute sense about how use applies to modules and how pub use is used to make the name publicly available to other modules.

Unless I'm doing something wrong of course, like I said I'm just learning Rust and I just wanted to report that.

Strongly agree. I also find myself unable to understand what would happen if pub use is not used.

"Scope" is the correct word to use rather than module, and I think the reference is actually imprecise in this case.

For example, this code doesn't compile because the use is local to the function's scope, not the whole module that both the const and the function are in:

const FOO: NonZeroI8 = NonZeroI8::new(5);

fn bar() {
    use std::num::NonZeroI8;
    
    let another = NonZeroI8::new(3);
}

For providing a better example of the effect pub use has, I think this issue is a duplicate of ##2716.

Thanks though!
