"we'll fix it later in this chapter" somewhat implies that a correct code example will be provided later; "later in this chapter" also implies "quite a bit later", when the fix is actually discussed very shortly after the non-compiling code is presented
"By following the help text’s suggestion, we restrict..." and "...and this example will compile..." imply to the reader that after this paragraph, they can expect to see a corrected code example. This rewording, though somewhat subtle, clarfies how the code example *would* be fixed by following the compiler's help message.

I'm an experienced programmer currently going through the book to learn Rust. A specific section of chapter 10.1 confused me a bit, and I found an existing issue indicating it confused other people too (#3658). I've opened a small PR to see if it can help make this section clearer.
Others in the discussion suggested some larger changes to the way the example is presented, but I think this should clarify things without requiring a non-trivial restructure.
