The key points of the text cover how to view Twilio account usage information using Rust. The author, Matthew Setter, explains that while Rust can be a harder language to learn than others, its features make it an attractive choice for developers. He provides a step-by-step guide on how to scaffold a new Rust project, add required dependencies, set environment variables, and write the necessary code to retrieve Twilio account usage information for the last month, sum up the total cost, and print that information to the terminal. The author also discusses the importance of handling errors gracefully and implementing additional features such as error handling in future improvements.
