How to build a dice roller in Rust

This tutorial provides a comprehensive guide to creating a web service for rolling dice using the Rust programming language and the Rocket framework, aimed at experienced programmers new to Rust. It begins by setting up the development environment with nightly Rust, creating a new project, and configuring dependencies like Rocket and regex. The guide explains the creation of routes for handling dice rolls, introducing the concept of dice notation, and implementing parsing logic to handle valid inputs. It then covers generating random dice rolls using the rand crate and details the calculation for both normal and critical hits. The tutorial also instructs on error handling using Rocket's response types and provides a method to format the roll results into a user-friendly string. The tutorial concludes with suggestions for extending the project, such as implementing character stat generation or tracking total dice rolls, and offers resources for further learning and debugging in Rust applications.
