Dometrain - Getting Started Rust

Rust is infamous for its steep learning curve, particularly around memory safety, but getting past the compiler is the key to writing highly performant, reliable software. This course is a practical, ground-up introduction to building backend applications in Rust. You will start with language fundamentals like data types, variable shadowing, and control flow before tackling memory management head-on. We break down exactly how ownership, borrowing, mutable borrows, and the Drop trait work together to guarantee memory safety without a garbage collector. From there, you will learn how to model data and handle errors idiomatically using enums, collections, and the Option and Result types.
With the core language mechanics in place, the course shifts entirely to real-world backend development. You will build an asynchronous CRUD web API from scratch, handling path and query parameters, JSON payloads, and HTTP status codes. Next, we integrate a database using SQLx, covering connection management, migrations, and how to leverage Rust for compile-time type checking on your SQL queries. You will then make the application configurable across environments using the config crate and configuration files. Finally, we cover how to write comprehensive integration tests for your asynchronous code, databases, and HTTP endpoints, wrapping up with the code changes and basic observability required to make your Rust application truly production-ready.
