In Rust, an array is a fixed-size collection of values of the same type. A slice is a view into a portion of an array. Arrays are useful when you know the number of elements at compile time, and slices let you work with a section of an array without copying data. When you need […]

In Rust, a tuple is a fixed-size group of values that can be of different types. You define a tuple using parentheses, like let person = (“Alice”, 30). Tuples are useful when you want to return or store multiple values together without creating a full struct. Tuples are one of the simplest ways to group

Rust supports standard operators for arithmetic (+, –, *, /), comparison (==, !=, <, >), and logic (&&, ||, !). These operators work on numbers, booleans, and some custom types, making them essential for performing calculations and decisions in your code. In this post, I will explain how to use operators in Rust. If you

Rust has two main string types: &str (a string slice) and String (a growable, heap-allocated string). &str is usually used for static or borrowed strings, while String is used when you need to modify or own the string data. In JavaScript, you often work with strings directly, and most of the time you do not

Rust has four main categories of scalar primitive types: integers, floating-point numbers, booleans, and characters. These types are built into the language, fixed in size, and form the foundation of all value handling in Rust programs. To write useful programs in Rust, you need to work with basic values like numbers, text, and true-or-false conditions.

In Rust, variable shadowing lets you reuse the same variable name in the same or a nested scope. Each shadowed variable is a new binding, which allows transformations or type changes without using a new name. When learning how Rust handles variables, one powerful feature to understand is shadowing. This lets you declare a variable

Rust is a statically typed language, which means every variable must have a type known at compile time. You can either write this type explicitly using type annotations, or let Rust figure it out automatically using type inference. Rust aims to make your code safe without making you write more than necessary. When you write

In Rust, constants are defined using const and must have a fixed type and value known at compile time. Unlike mutable variables, constants never change and can be used throughout your code wherever needed. Use const for values like limits, defaults, or settings that should stay the same. Once you understand how variables work in

In Rust, variables are declared using let. By default, all variables are immutable, which means you cannot change their values. To make a variable mutable, add mut like this: let mut x = 5. This is different from JavaScript, where variables are often mutable by default. When you begin writing real programs in Rust, you

To write your first Rust program, use cargo new project_name, then open main.rs and add a main function with a println! macro. This prints a message to the terminal. Rust programs always start from the main function. Once your Rust environment is set up, the next step is to write and understand your first program.
