A HashMap is like a real-world dictionary where you look up a word (key) to find its meaning (value). In Rust, a HashMap stores data in key-value pairs, where each key must be unique. It is defined as: Every key is unique; you can’t have two keys that are the same. Keys and values can … Read more

A Vector in Rust is a growable array that can store multiple values of the same type. You can define it using Vec<T>, where T is the type of the elements (like i32, String, etc.). Vectors are stored on the heap, so you can add or remove elements while the program is running. You don’t … Read more

Collections in Rust are special data structures that can hold multiple values together. collections can grow or shrink dynamically as you add or remove elements. They allow you organize and manage groups of data efficiently. Rust provides several commonly used collections: Each collection is optimized for specific use cases, and selecting the right one is … Read more

What Are Crates in Rust? A crate in Rust is a package of Rust code that the compiler can compile. It is the basic building block of Rust programs. Every Rust program is made up of at least one crate. Crates help organize code, reuse functionality, and share code across projects. There are two main … Read more

Modules in Rust are like folders in a project. They help you organize related code, such as functions, structs, enums, and constants, together in one place. Modules also act as namespaces, which means they prevent naming conflicts between items with the same name in different parts of your program. In short, Rust modules help structure … Read more

What Is Rust Generic? Generics in Rust allow you to write code that can work with different data types without rewriting it again and again for each type. Instead of fixing a type (like i32 or String) in your code, you write it generically, and Rust will automatically figure out the actual type when you … Read more

What are the Traits? A trait in Rust is a collection of methods that define what methods a type must have. It allows you to share common behavior between different data types When a type implements a trait, it agrees to follow the rules written inside that trait by writing the actual code for those … Read more

Struct methods are defined within an impl (implementation) block for a struct. These methods can do multiple things, like: Types of Struct Methods In Rust Rust supports two types of struct methods: How To Use Instance Methods In Rust? This method works with a specific instance of a struct. It has access to the struct’s … Read more

What are Structs? A struct is short for structure. It’s like a container that groups different pieces of data under one name. Structs are similar to objects in object-oriented programming, but a struct itself doesn’t have methods; it only stores data. Types of Structs in Rust Rust provides us with different styles of structs, depending … Read more

What is Pattern Matching? Pattern Matching in Rust means checking a value against different possible shapes (patterns) and then running code depending on which one matches. The following tools were used for this: The Syntax of Pattern Matching Basic Syntax of match: match value { pattern1 => action1, pattern2 => action2, _ => default_action,} Simple … Read more
