Rust Programming Cookbook

How it works...

Rust's documentation is very versatile and allows for variations on doctests that would not be possible to cover in a single recipe. However, the documentation of these tools is also excellent, so, for more details, check out https://doc.rust-lang.org/rustdoc/documentation-tests.html.

What we covered in this recipe is a great way to document structs and functions in your code by adding examples that will be compiled and run on every test run. Not only will these be helpful for your readers and regression testing, but they also require you to think about how the code works as a black box. These tests are executed whenever code (``` in a fence ```) is encountered in the Example section of the documentation. In step 2 and ...
