Defining Structs

Zig structs define custom types with fields and methods.

Introduction to Zig Structs

Zig structs are a fundamental feature in Zig, allowing developers to define custom data types. These structs can contain fields and methods, enabling encapsulation and data abstraction. By using structs, you can model complex data structures more effectively in your applications.

Defining a Struct in Zig

To define a struct in Zig, use the struct keyword followed by a set of fields enclosed in curly braces. Each field has a name and a type. Here is a simple example of a Zig struct:

Accessing Struct Fields

Fields in a Zig struct are accessed using the dot notation. Once you have an instance of a struct, you can read or modify its fields. Here's how you can access fields in the Point struct:

Initializing Structs

Structs in Zig are initialized using a special syntax that specifies field values. This initialization can be done directly by listing the field names and their corresponding values:

Nested Structs

Zig structs can be nested within other structs, allowing for the creation of complex data models. Here is an example where a Rectangle struct contains two Point structs:

Conclusion

Zig structs are versatile and powerful tools for creating custom data types. They support encapsulation, make your code more organized, and help model real-world entities. As you advance, you'll explore how to add methods to structs in the next post.
