Error in code snippet in Chapter 14.3

[michaelrevans]

In Chapter 14.3, the example gives add-one/src/lib.rs as

#![allow(unused)]
fn main() {
pub fn add_one(x: i32) -> i32 {
    x + 1
}
}

but it should be without main, like

pub fn add_one(x: i32) -> i32 {
    x + 1
}

The listing it references is correct, so there must be some other behaviour adding the surrounding main function that needs to be disabled/removed.], hence why I'm opening an issue not a PR

Yes, this is a standard thing rustdoc does. If we wanted to, we could modify the example so it's not shown that way. There are some other tickets about similar stuff elsewhere on the tracker.

Thanks! I found a hack for this but missed a whole bunch of spots... thank you for helping me find them!
