Getting Started with V Programming

Getting Started with V Programming

By: Pavan Kumar Rao

Overview of this book

A new language on the block, V comes with a promising set of features such as fast compilation and interoperability with other programming languages. This is the first book on the V programming language, packed with concise information and a walkthrough of all the features you need to know to get started with the language. The book begins by covering the fundamentals to help you learn about the basic features of V and the suite of built-in libraries available within the V ecosystem. You'll become familiar with primitive data types, declaring variables, arrays, and maps. In addition to basic programming, you'll develop a solid understanding of the building blocks of programming, including functions, structs, and modules in the V programming language. As you advance through the chapters, you'll learn how to implement concurrency in V Programming, and finally learn how to write test cases for functions. This book takes you through an end-to-end project that will guide you to build fast and maintainable RESTful microservices by leveraging the power of V and its built-in libraries. By the end of this V programming book, you'll be well-versed with the V programming language and be able to start writing your own programs and applications.

Defining methods for a struct

V allows us to define methods for a struct. A method is a function with a special receiver argument that appears between fn and the method name. They allow us to add functions to a struct in a convenient manner. Methods are the kind of functions that access the properties of the struct to perform some routine. To define a method for a struct, follow the syntax shown here:

fn (r RECEIVER_TYPE) METHOD_NAME(OPTIONAL_INPUT_ARGUMENTS) RETURN_TYPE {
        METHOD BODY
}

In the preceding syntax, the RECEIVER_TYPE indicates the name of the struct to which the method belongs. If you are familiar with the C# programming language, this feature is similar to the concept of extension methods in C#. During runtime, the methods of a struct have access to the values held by the fields of the struct. Therefore, the methods help to evaluate logic or perform desired operations with the struct fields.
