Practice It: Rust File Manipulation

Course details

In this course, learn coding best practices and gain greater proficiency in Rust by completing common programming tasks. These tasks include file manipulation, construction of functions, and the usage of collections such as Vec and Hashmaps. In the end, instructor Marcus Willock brings this list of tasks together to complete your final exam: read a file, change the targeted words of that file at will, and then create a new file with your changes. In more explicit terms, take the first chapter of Alice in Wonderland and remove Alice from the story and replace her with yourself.
