Dereferencing is how we access the value that a reference points to. References are like signposts that guide us to the actual data. Imagine them as arrows pointing to a treasure! 💎 Technically, a pointer stores the address of another variable in memory. So, if we do something like the example below: my_ref will hold the address of x in memory. In that case, x is not equal to my_ref, make…

Raw String in Rust

If you are looking for an easy way to work with text in Rust in a way that special characters don’t matter — for example, when you are looking to parse HTML, one way you can do this is by using raw string in Rust. The syntax Raw strings starts with r# and closes with a # like so: r#””# Example An example of a raw string will look like…
Choosing Between &str and String in Rust
In Rust, handling text is a common task, and understanding when to use `&str` and when to use `String` is key — it could lead to more efficient code when done right or otherwise when misused. When you have passed the stage of just getting your Rust code to work you want to make it more efficient. And you want to understand how string really works. While Rust has only…
Rust Lifetimes Simplified

- – Make a comment on Rust Lifetimes Simplified
This guide is an attempt to simplify Rust Lifetimes, it’s a series and will be divided into several chapters. We’ll start with chapter one today. Chapter 1 Lifetimes and its benefits In Rust programming, lifetimes is a critical yet misunderstood concept. Assuming we are not talking about programming, when we talk about lifetimes what comes to mind? According to Oxford Dictionary, a lifetime is the duration of a person’s life…
Understanding Rust’s memory magic with an analogy
Imagine a town, where Mrs. Ifeoluwa owns a beautiful home that she’s decided to sell. In this town, there is a strict regulatory body (comparable to Rust’s Borrow Checker) that maintains order and ensures the rules are followed. Mrs. Ifeoluwa, as the sole owner of her house, has exclusive rights to it (the principle of Ownership). She goes to the regulatory body and notifies them about her intention to sell…

Rust is the most loved language right now — sounds like a cliche already 😃, but it’s true. In fact, it has been added to the Linux Kernel and going to be added to the Windows Kernel. Not every language enjoys that kind of privilege and love, you know. One of the benefits of Rust is that it’s fast, if you have implemented something awesome in Rust and you want…
Introducing Rust in simple English
Rust is a statically typed programming language that allows developers to build high-quality and efficient software. Rust takes memory management very seriously. While it allows you to manage your memory, it does so in a way that provides safety guarantees. Rust’s memory management system is based on the concept of ownership and borrowing. The ownership and borrowing system is a unique feature of Rust that brings together a combination of…
Rust trait implementation with a “where” clause
In today’s Rust Journey piece, we’ll discuss one concept that might confuse new Rust Developers — the where clause in the Rust trait implementation workflow. The where clause allows developers to enforce strict constraints on generic types which will result to code that is reliable, easier to maintain, and less prone to errors. While you can use the where clause in different context, our examples will be focused on how…
