Working on an Existing Cargo Project
If you download an existing project that uses Cargo, it’s really easy to get going.
First, get the project from somewhere. In this example, we’ll use
cloned from its repository on GitHub:
$ git clone https://github.com/rust-lang-nursery/rand.git $ cd rand
To build, use
$ cargo build Compiling rand v0.1.0 (file:///path/to/project/rand)
This will fetch all of the dependencies and then build them, along with the project.
