About this course

Understanding how to pass parameters efficiently is critical for writing high-performance and robust code in the D programming language. This course teaches you the fundamental principles of using `const ref` parameters, enabling you to write faster, safer, and more idiomatic D code that respects strict immutability constraints. This knowledge is essential for optimizing performance without sacrificing data integrity, especially when dealing with large structural types like structs and classes. What you'll learn: * Understand the difference between value, reference, and pointer passing semantics in D. * Master the syntax and application of the `const ref` parameter combination for optimal memory usage. * Apply `const ref` correctly when overloading functions to ensure the compiler selects the most efficient version. * Practice ensuring immutability for variables within structs and classes passed by reference. * Configure D functions using attributes like `pure` and `nothrow` that benefit from safe reference passing. * Build efficient function signatures that avoid costly copies of large data structures. We begin by establishing core D concepts around memory management and ownership, move into practical examples of function signatures, and then explore how `const ref` interacts with structural types and function overloading rules. This course is designed for beginner programmers starting with D or those familiar with other languages who need a deep understanding of D's parameter passing semantics. No prior knowledge of D is required. Start building faster, safer D applications today.
