"Rust: A xkcd comic fetcher that converts it to ASCII art" Task for Google Code-In 2019
$ cargo run -- [--comic_id {id}]
When the program is run with a comic_id variable, it fetches the comic with that id. If the comic doesn't exists it throws and error otherwise it shows the ascii represantation of the comic. Without the comic_id parameter, the program fetches a random comic and shows it.
