C, Java and Rust
1. Introduction The Rust language provides iterators that make complex data structures easy to traverse, transform, and filter. Common iterators in Rust include iter(), iter_mut(), and into_iter(). Iter() and into_iter() are provided for different...
1. Overview Data types are essential components of virtually every programming language. Rust is a strongly typed language with various built-in types. While modern IDEs often help preview variable types, there may be cases...
1. Introduction Remote servers are essential in modern computing and are used by many institutions from small businesses to enterprises. SSH (Secure Shell) is a protocol that allows secure remote access to systems. By...
1. Overview As we know, we can represent text as a String or string literal (&str) in Rust. A String is a growable, mutable, owned string type, while a string literal is an immutable reference...
1. Overview Converting a string to an integer type is a common task in Rust, especially when working with user input which is primarily text-based. In this tutorial, we’ll learn how to safely and...
1. Overview In this tutorial, we’ll learn through a step-by-step guide on building a CRUD (Create, Read, Update, Delete) REST API using Actix Web and PostgreSQL. We’ll build an API for a simple book...
1. Overview Vector (Vec<T>) is a collection in Rust that allows storing multiple values of the same type in a single data structure. Unlike an array, Vectors can grow or shrink in size. In...
1. Overview In this short tutorial, we’ll discuss how to split a string into two parts using Rust. 2. Using split_at() split_at() method is part of the Rust standard library, it provides easy functionality to...
1. Overview Reading from and writing to files is a common task in the programming world. Rust standard library provides functions to work with files. In this tutorial, we’ll delve into the basics of...
1. Overview Iterating through an Enum value may be tricky in Rust. However, a third-party crate called strum makes the process easier. In this tutorial, we’ll explore how to use strum to iterate over an...
1. Overview To allocate memory dynamically in C, we use functions like malloc() and calloc(). Both allocate memory on the heap, but have different initialization behavior. Common use cases of memory allocation in C...
