REST APIs with Actix-web/Rocket

REST, or REpresentational State Transfer, is an architectural style for networked applications. It defines a set of principles for how web services should communicate.

Think of it as a set of guidelines for building web services that are stateless, cacheable, and use standard HTTP methods to interact with resources.

• Resources: Anything that can be named, like a user, a product, or an order.
• URIs: Unique identifiers for resources (e.g., /users/123).
• HTTP Methods: Standard actions performed on resources (GET, POST, PUT, DELETE).

Rust brings unique advantages to web service development, making it a strong choice for high-performance and reliable APIs:

• Performance: Rust's zero-cost abstractions mean highly efficient code, often comparable to C/C++.
• Memory Safety: The ownership system prevents common bugs like null pointer dereferences and data races, leading to more robust services.
• Concurrency: Rust's async/await model, combined with its safety guarantees, makes building concurrent web services 'fearless'.
• Reliability: Strong type system and compile-time checks catch many errors early.
