Hands-On Data Structures and Algorithms with Rust

The compile and run commands

As the main build tool, cargo does compile and run by way of creating and then executing the output binary (usually found in target/<profile>/<target-triple>/).

What if a library written in a different language is required to precede the Rust build? This is where build scripts come in. As mentioned in the Project configuration section, the manifest provides a field called build which takes a path or name to a build script.

The script itself can be a regular Rust binary that generates output in a designated folder, and can even have dependencies specified in Cargo.toml ([build-dependencies], but nothing else). Any required information (target architecture, output, and so on) is passed into the program using environment ...
