What Are Crates in Rust? A crate is the smallest unit of code that the Rust compiler understands. It can be a binary (executable program) or a library (reusable code). Crates provide functionality, organization, and a way to share code across projects. Types of Crates Example: Creating a Binary Crate Initialize a New Binary Crate … Read more

Modules allow you to group related functions, structs, enums, constants, and other items together. What Are Rust Modules? A module in Rust is a namespace that organizes code and prevents naming conflicts. Modules can also control the visibility of items (public or private) to ensure encapsulation.

Rust Generics: A Comprehensive Guide with Examples Generics in Rust allow you to write flexible, reusable, and type-safe code. They enable you to create functions, structs, enums, and traits that can operate on different types without sacrificing performance or safety. Generics are a core feature of Rust, ensuring type abstraction while maintaining strict compile-time checks. … Read more

What are Traits in Rust? A trait in Rust is a collection of methods that define shared functionality. Any type that implements a trait must provide the functionality defined by the trait. Traits are useful for enabling polymorphism, making your code more modular and reusable. Key Features of Traits Defining a Trait A trait is … Read more

What are Structs? A struct (short for “structure”) in Rust is a custom data type that lets you name and group multiple related values of different types into a single entity. Structs are similar to objects in object-oriented programming but without methods. Types of Structs in Rust Rust supports three main types of structs: Defining … Read more

What is Pattern Matching? Pattern matching in Rust is a mechanism to compare a value against a series of patterns and execute code based on the first pattern that matches. It is primarily achieved using the match and if let constructs. The Syntax of Pattern Matching Basic Syntax of match: match value { pattern1 => … Read more

What Are Enums in Rust? Enums, short for “enumerations,” are custom types that can represent multiple related values, each as a variant. They are particularly useful for scenarios where a value can only be one of a predefined set of possibilities. Defining an Enum You define an enum using the enum keyword followed by the … Read more

What Are Tuples in Rust? A tuple in Rust is a collection of values grouped together into a single unit. Each value in a tuple can have a different type, and the tuple itself has a fixed size, meaning it cannot grow or shrink. Tuples are denoted using parentheses () and the elements are separated … Read more

What Are Array Methods in Rust? Array methods in Rust are built-in functions that can be called on arrays to perform operations like iteration, transformation, or querying properties. These methods ensure safety and efficiency by leveraging Rust’s ownership and borrowing rules. Key Array Methods in Rust Below is a detailed explanation of the most commonly … Read more
