  • This discrepancy is not present in main

URL to the section(s) of the book with this problem: https://rust-book.cs.brown.edu/ch10-02-traits.html

Description of the problem: The last sentence of "Returning Types That Implement Traits" is "We’ll cover how to write a function with this behavior in the “Using Trait Objects That Allow for Values of Different Types” section of Chapter 17."

Suggested fix: This should read as "We’ll cover how to write a function with this behavior in the “Using Trait Objects That Allow for Values of Different Types” section of Chapter 18."

Note: chapter numbering is not the same between the Experimental and main book, due to the insertion of chapter "17. Async and Await". This may explain the discrepancy.
