we need to be explicit about the dependency relationships.

Next, let’s use the `add_one` function (from the `add_one` crate) in the
`adder` crate. Open the _adder/src/main.rs_ file and add a `use` line at the
top to bring the new `add_one` library crate into scope. Then change the `main`
`adder` crate. Open the _adder/src/main.rs_ file and change the `main`
function to call the `add_one` function, as in Listing 14-7.
