What are Command Line Arguments? Command-line arguments are extra pieces of information you provide to a program when you run it from a terminal or command prompt. They allow users to pass input to the program without modifying the code, making the program more flexible and configurable. Example: Command-Line Input $ my_program arg1 arg2 arg3 … Read more

What is File Handling? File handling is the process of working with files in your system. Such as creating, reading, writing, updating, or deleting the file. This is an essential part of programming when you want to store data and interact with external resources. Rust provides us a powerful tools for file management through its … Read more

What is RefCell<T>? RefCell<T> is a special kind of smart pointer that allows you to change the value inside even if the container itself is not marked as mutable. Normally, Rust’s strict borrowing rules are checked at compile time. You can have either one mutable reference or many immutable references, but not both at the … Read more

The Arc<T> stands for Atomic Reference Counted smart pointer. It is a powerful tool that allows multiple threads to share ownership of the same data safely. Rc<T> is only safe for single-threaded programs, but Arc<T> is a multi-threaded version and uses atomic operations to ensure thread safety. It allows multiple threads to share ownership of … Read more

In Rust, Rc<T> stands for a reference-counted smart pointer. It is a powerful feature that allows multiple parts of your program to share ownership of the same data stored on the heap. With Box<T>, only one owner can exist at a time, but with Rc<T>, you can have multiple owners safely reading the same data … Read more

In Rust, Box<T> is a smart pointer that allows you to store data on the heap instead of the stack. By default, most values in Rust are stored on the stack because it’s fast, but the stack has a fixed size and is not able to store large data, dynamically sized data, or recursive types. … Read more

A smart pointer is a special type of data structure that behaves like a regular pointer. it stores the memory address of some data, but it also does much more than that. Smart pointers come with built-in features like: In simple terms, a pointer is just a reference to some data in memory. But a … Read more

Rust is famous for its safe programming languages, and it automatically checks for memory safety, prevents data races, and protects your programs from many common bugs at compile time. Rust allows you to write unsafe code for your program to better interact with memory, hardware, or external systems. Unsafe code is a means to understand … Read more

Benchmarking measures the time taken by the code to run, allowing us to understand its performance. You can easily know how much time a function or algorithm takes, so you can: Setting Up Benchmarking in Rust Rust provides built-in support for benchmarking using the bencher crate. However, it’s available only on the nightly version of … Read more

Attributes in Rust are extra instructions or metadata that you attach to code elements like functions, structs, enums, or modules. They guide the compiler or tools on how to treat the code. Syntax of attributes: Attributes start with # and are inside square brackets. For example: #[attribute_name] Types of Rust Attributes Rust attributes can be … Read more
