 * `Option` and `Result` are widely used not just in the standard library.
 * `Option<&T>` has zero space overhead compared to `&T`.
 * `Result` is the standard type to implement error handling as we will see on Day 3.
-* `binary_search` returns `Result<usize, usize>`.
-  * If found, `Result::Ok` holds the index where the element is found.
-  * Otherwise, `Result::Err` contains the index where such an element should be inserted.
+* `try_into` attempts to convert the vector into a fixed-sized array. This can fail:
+  * If the vector has the right size, `Result::Ok` is returned with the array.
+  * Otherwise, `Result::Err` is returned with the original vector.
