What is Deserialization? Deserialization is the process of taking structured data from a format like JSON, TOML, YAML, or binary and converting it into a Rust data structure, such as a struct, enum or collection. It allows Rust programs to read, interpret and process external data. Common Use Cases: How to Perform Deserialization in Rust … Read more

What is Serialization? Serialization converts data structures into a specific format so they can be stored in files, sent over a network, or saved in a database. The reverse process, deserialization, converts the serialized data back into its original structure. Common Use Cases of Serialization: Serialization in Rust In Rust, the most popular library for … Read more

What are Command Line Arguments? Command-line arguments are extra input values provided to a program when it is run from a terminal. These inputs are passed after the program name and are typically used to configure how the program behaves. Example: Command-Line Input $ my_program arg1 arg2 arg3 Why Use Command Line Arguments in Rust? … Read more

What is Writing to a File? Writing to a file means storing data in a file on your system. This can involve: Rust uses the std::fs module for file operations and the Write trait from the std::io module to handle file writing. How to Write to Files in Rust Here are the most common ways … Read more

What is File Reading in Rust? File reading in Rust involves opening an existing file and retrieving its contents. Rust provides several ways to read files based on the file size and your use case, such as: Rust’s std::fs and std::io modules are used to perform these operations safely. How to Read Files in Rust … Read more

What is File Handling? File handling refers to performing operations like: Rust achieves this with the std::fs module for file management and the std::io module for input/output operations. Key File Operations in Rust Here are the most common file operations in Rust explained with examples: 1. Creating a File To create a file, use the … Read more

Why Optimize Rust Programs? Even though Rust is inherently fast, specific use cases like game development, systems programming, or high-frequency trading demand additional fine-tuning. Optimization helps to: 1. Use Iterators Instead of Loops Rust’s iterators are highly optimized and use zero-cost abstractions, meaning they perform as well as hand-written loops. Example: Using Iterators fn main() … Read more

What is RefCell<T> in Rust? RefCell<T> is a smart pointer that allows mutable borrowing of data even when the RefCell itself is immutable. Rust enforces borrowing rules—like one mutable or multiple immutable references—at runtime instead of compile time with RefCell. This makes RefCell particularly useful in cases where the compiler’s strict rules on borrowing are … Read more

The Arc<T> pointer in Rust stands for Atomic Reference Counting. It is a thread-safe smart pointer that allows shared ownership of data between multiple threads. Unlike Rc<T>, which is only safe for single-threaded programs, Arc<T> uses atomic operations to ensure thread safety. What is Arc<T> in Rust? Arc<T> is a thread-safe version of Rc<T>. It … Read more

The Rc<T> pointer in Rust stands for Reference Counted. It is a type of smart pointer that enables shared ownership of data. Unlike the Box<T> pointer, which allows a single owner, Rc<T> allows multiple owners to read the same data while maintaining Rust’s safety guarante What is Rc<T> in Rust? Rc<T> is a smart pointer … Read more
