-// This is similar to the previous `from_into` exercise. But this time, we'll
-// implement `FromStr` and return errors instead of falling back to a default
-// value. Additionally, upon implementing `FromStr`, you can use the `parse`
-// method on strings to generate an object of the implementor type. You can read
-// more about it in the documentation:
-// https://doc.rust-lang.org/std/str/trait.FromStr.html

-// TODO: Complete this `FromStr` implementation to be able to parse a `Person`
-// out of a string in the form of "Mark,20".
-// Note that you'll need to parse the age component into a `u8` with something
-// like `"4".parse::<u8>()`.
-//
-// Steps:
-// 1. Split the given string on the commas present in it.
-// 2. If the split operation returns less or more than 2 elements, return the
-//    error `ParsePersonError::BadLen`.
-// 3. Use the first element from the split operation as the name.
-// 4. If the name is empty, return the error `ParsePersonError::NoName`.
-// 5. Parse the second element from the split operation into a `u8` as the age.
-// 6. If parsing the age fails, return the error `ParsePersonError::ParseInt`.
