In the previous chapter, we saw the following directory hierarchy:
foo ├── Cargo.toml └── src └── main.rs
Suppose that we wanted to have two binaries in the same project, though. What then?
It turns out that
cargo supports this. The default binary name is
we saw before, but you can add additional binaries by placing them in a
foo ├── Cargo.toml └── src ├── main.rs └── bin └── my_other_bin.rs
cargo to only compile or run this binary, we just pass
--bin my_other_bin flag, where
my_other_bin is the name of the binary we
want to work with.
In addition to extra binaries,
cargo supports more features such as
benchmarks, tests, and examples.
In the next chapter, we will look more closely at tests.
