Rust: Structs

Structs are a fundamental part of Rust programming. They allow you to define custom data types that can hold multiple pieces of data together. In this blog post, we will explore how to create and use structs in Rust.

Defining Structs

To define a struct in Rust, you use the struct keyword followed by the name of the struct and its fields:

```rust struct Person { name: String, age: u32, } ```

In this example, we have defined a struct called Person with two fields: name of type String and age of type u32.

Creating Instances of Structs

To create an instance of a struct, you use the struct's name followed by curly braces containing values for each field:

```rust let person = Person { name: String::from("Alice"), age: 30, }; ```

Accessing Struct Fields

You can access the fields of a struct using dot notation:

```rust println!("Name: {}", person.name); println!("Age: {}", person.age); ```

Common Use Cases

Structs are commonly used to represent real-world entities in Rust programs. For example, you could use a Car struct to represent a car with fields like make, model, and year.

Practical Applications

Structs are essential for organizing and managing data in Rust applications. They provide a way to encapsulate related data and behavior into a single unit, making your code more modular and easier to maintain.

Importance in Interviews

Understanding how to work with structs is crucial for Rust developers, especially in technical interviews. Interviewers often ask candidates to write code that involves creating and manipulating structs, so being familiar with this topic can give you a competitive edge.

Conclusion

Structs are a powerful feature of Rust that allow you to define custom data types and organize your code effectively. By mastering structs, you can write more maintainable and structured Rust programs.
