Customizing the build

cargo is versatile—something that we have already established in the previous recipes in this chapter. However, we did not touch configuring the tools cargo uses to compile and run Rust projects. For this, there are multiple ways, as they apply to different domains.

In this recipe, we are going to explore two ways by customizing the build of a new project.

How to do it...

1. Create a new binary project using cargo new custom-build and open the project folder using VS Code.
2. Open src/main.rs and replace the hello world code with the following:

fn main() {
