Rocket leverages Rust's type system to provide compile-time safety for routes, request guards, and data handling.

It offers a simple and expressive API for building web applications with minimal boilerplate.

Supports asynchronous request handling with Rust's async ecosystem.

Includes features like templating, database integration, JSON handling, and state management.

Highly modular, allowing integration with various databases, middleware, and authentication libraries.

Routing macros for concise endpoint definitions

State management across requests

Database integration via Diesel, SQLx, or other ORMs

Custom request guards for authentication/validation

Middleware via Fairings and Guards

Route - defines endpoint URL and handler function

Request Guard - validates or parses incoming requests

Responder - converts Rust types into HTTP responses

Fairing - hook for requests/responses lifecycle

State - shared data accessible in request handlers

src/main.rs - main entry point

src/routes/ - route handler modules

src/models/ - data and ORM models

templates/ - HTML or Tera/Handlebars templates

Cargo.toml - project and dependency configuration
