Rust Programming Cookbook

How it works...

This recipe is set up like a large benchmark or testing scheme: in Step 1, we define the functions to be tested, each with different input parameters, but the same behavior; it fills Vec up to a minimum sum. These parameters reflect different ways of sharing ownership, including RefCell, Cell, and Cow.

Steps 2 and 3 create tests that work exclusively on the different ways adopted by RefCell and Cell of handling and failing these values. Step 5 does something similar to the Cow type; all are great opportunities to test out your own theories as well!

In Steps 4 and 6, we are creating and running benchmarks and tests on the functions we created in this recipe. The results are surprising. In fact, we tried different computers ...
