This way +data to be encoded will never contain any numbers and numbers inside data to +be decoded always represent the count for the following character. + +## Rust Installation + +Refer to the [exercism help page][help-page] for Rust installation and learning +resources. + +## Writing the Code + +Execute the tests with: + +```bash +$ cargo test +``` + +All but the first test have been ignored.
