RUST Crab  Coding in the Sea

What's the buzz with RUST? Hold your keyboards, we're about to spill the code 🕵️‍♂️💻. Why is RUST stealing the spotlight? What's the hype about? What makes DevOps set sail in approval🌊⚓️? Why should Business Owners even care to put RUST on their radar? Let's crack some cRUST 🦀.

First Things First

Let's rewind a bit with the back story. RUST grew out of a personal project that begun in 2006 by Mozilla Research employee Graydon Hoare. Afterwards he was hired by Apple to work on Swift. The brainchild of a community striving for safer and more efficient systems programming, RUST is here to shake things up.

Design Goals & Principles

But why should you care?🤷‍♂️ RUST's got a mission, and it's not keeping it a secret. Design goals that scream "performance matters," and principles that shout "safety first." This language isn't playing around. RUST is not your best choice to get your feet wet. This is a language which serious heels and steep learning curve.

The Nuts and Bolts

Alright, let's talk basics. Syntax? Check. Data types and variables? Double-check. Control flow that feels like a smooth beat (if statements, loops)? Triple-check. Without these items components, named here, you don't have a programming language in the 'Procedural' family tree. E.g. It's basically procedural but gives you the Artistic or Poetic Freedom to literally 'express yourself' in a more functional way. Functions as first class citizens, check. Closures check once more. Iterators at no extra cost in the standard model (zero cost abstracion.).

Key Features and Benefits

Now it's time to uncover the treasures that make this programming language a true captain of the code seas. Let's navigate the key features and bask in the benefits. Let's dive in!

⚓️ Ownership and Borrowing

RUST's ownership system is like having a crew that guards your ship's treasure with unmatched vigilance, your secure anchors in the code ocean. The concept of borrowing and lifetimes acts as your ship's anchor, ensuring your code stays afloat and secure. No unexpected leaks or pirate attacks on your data – just smooth sailing. Imagine your code as a ship at sea. RUST ensures that each piece of data has a designated owner, just like a captain taking responsibility for their cargo. The borrowing concept is like letting crew members use equipment temporarily without giving them ownership. It keeps everything organized, secure and prevents unexpected mishaps. But this metaphor, however it's not doing enough justice to the Ownership system. RUST helps you prevent a lot of security and programming problems while not sacrificing speed. Lifevests in the form of a memory manager with the periodically returning Garbage Collector that slows you down to the max, no sir. We start by not creating garbage at all. In RUST we solve problems by taking "ownership". Wouldn't your Therapist be proud of you? And the Ownership rules and subsequent Borrowing tactics are not only for making your programming journey more safe and reliable, it also helps you to act like a better Software Engineer. Coding you do in the cargo hold, real Software Engineering captains sail the big ships.

🌊 Memory Safety

RUST the unsinkable ship of programming languages. With zero-cost abstractions and a vigilant borrow checker, you're not just sailing; you're sailing confidently, knowing that your ship is watertight against common programming errors. In the coding world, avoiding mistakes is crucial. RUST acts like a shipbuilder constructing an unsinkable vessel. The borrow checker acts as the inspector, making sure every part of your ship is in top-notch condition. This way, you can sail smoothly without worrying about common errors causing your ship to sink or Pirates to hijack it due to forgotten leaks in your defenses.

⚙️ Concurrency and Parallelism

RUST's concurrency features let your ship sail on multiple threads without hitting stormy seas. RUST provides mean to sail the seas of code in concurrency, I present to you even fearless concurrency, due to it's ownership and lifetimes model.

Benefits for the (DevOps) Code Navigator: RUST brings a code ship that's not only reliable but also performs like a well-tuned engine, cutting through the digital waves with style.RUST makes sure your code ship is organized, secure, and built to withstand the challenges

Benefits for the Business (Owners) Sea Captains: Increased reliability means less time dealing with code crises and more time steering the ship toward business success. A high-performance vessel, saving time and resources. It's like having a trustworthy partner on the coding sea.

Let's face it the best of Programmers make errors (dot). Programmers have proven to have not the sharpest eye for memory leaks, dangling pointers etc. RUST is a vessel that can only be sailed properly. Your ship won't leave the docks into the oceans until it's proven not too sink. Remember the ancient RUST proverb: "The safest program, is the program that doesn't compile". If it doesn't

compile, it's back to the implementation or maybe even design table. RUST let's you think before you code. As the Ancient Wise Man Senaca once stated; if you don't know the directions to your Harbor, no wind will blow in the right direction.

Considerations & Mitigations.

Safeguarding Your Code Assets. Alright, code champions, let's talk shop. As we cruise through the RUSTy coding avenues, there are a few pit stops to consider. Let’s break it down.

🚧 Error Handling

Navigating Code Storms. Code isn't always sunshine and rainbows. RUST knows this, and it equips you with weatherproof gear in the coding storms. Handle errors like a boss, ensuring your code ship stays resilient even when the coding forecast turns gloomy. Try/catch will make your course overcomplicated. In RUST we handle errors by taking the Narwal by the Horn when we see it.

  • Result and Option types: Many boats sailing under the flags of different languages like C, C++, C# and Java have found an early watery grave by pursuing the Elusive Siren of the coding seas, she goes by the name of Null or Nil🧜‍♀️. Beautiful and elegant as she is, she lured many coder to the chasms of the segmentation faults. In RUST we deny the void, the Null and the Nil. If there's nothing to return we use Option to declare there's nothing to return and otherwise just our payload. And for Errors, well my good Landsman, it's never an Option it's a Result. That way never have to listen and succumb to the beautiful wailing of the lady Nil.

  • The Result and unwrap patterns: These are like your contingency plans. Unwrapping errors gracefully, RUST ensures you can troubleshoot without causing a code shipwreck. It's about maintaining composure in the face of unexpected coding weather.

  • panic!: We do have panic by the way in RUST, but without the Recover. A Panic is when there's no way out, it's irrecoverable, and we go down with our Ship, Captain's Honour 👨‍✈️.

  • ? operator and the Error trait: Imagine these as your automatic translators. They help your code communicate effectively, ensuring your team understands and can address any errors that may arise. The problem on big Frigates is communication. Sir, the cargoholds are leaking, it's smoking in the Powder Room. And here we do not mean fair ladies taking a smoke while powdering their nodes. This could mean the end of the ship due cascading failures. But how do we communicate these errors among the decks. In RUST we have similar problems and we propagate errors with the ? operator. Communicating clearly and concisely. And enriching their context with Error traits.

🔄 Traits and Generics

Flexibility at Your Fingertips. In the dynamic oceans of coding, adaptability is key. Traits and generics in RUST act like your coding chameleons, blending seamlessly into any scenario. Keep an eye on trait bounds; they're the guardrails keeping your code journey smooth and steady.

Sometimes a ship is a ship, sometimes it's a sloop, sometimes three-master sailing under her Majesty's Royal Navy. Traits allow you to build ships using characteristics and behaviour that you can add to the basics. Yes, matey, in RUST we reject the false belief that all OOP is Inherited. We prefer Composition over Inheritance. And using Generics we make sure we never have to repeat or orders for every type we process.

  • Trait system in RUST: Think of traits as your code's unique skill sets. They allow your code to wear different hats based on the situation, making it adaptable to various tasks.

  • Defining and implementing traits: These are your job descriptions and skill development plans. Define what you need, and RUST ensures your code has the right skills to get the job done.

  • Generics and parametric polymorphism: Generics are your code's multitool, capable of handling different data types. It's like having a universal remote for coding tasks, simplifying complexities. Parametric polymorphism is a programming language feature that allows a function or a data type to operate on values of different types in a generic way, without specifying the actual types during definition. In other words, it enables writing code that can work with a range of data types while maintaining type safety.

  • Trait bounds and associated types: Setting boundaries is crucial. RUST ensures your code stays within its designated lanes, avoiding any unforeseen detours.

⚠️ Advanced Features.

Navigating Uncharted Territories. Sometimes you need to push the boundaries. Enter Unsafe RUST, your passport to uncharted coding territories. But, and it's a big but, wield it wisely. Think of it like a power tool – use it when needed, not just for the thrill.

Like to sail dangerously matey? Embark on a journey to sail under the flag of 'Unsafe' RUST. Not for the faint of heart. No guard rails, no swimvests.. nothing to protect your from the Krakens and Poisonous Seasnakes. It's easy to fall overboard and end up in the boundless depths of memory errors. But, the bounty and rewards are good and someone needs to discover Terra Incognita and chart it for the less adventurous sailers among us.

  • Pattern matching with match: Picture this as orchestrating a symphony. Match helps your code play the right tune based on specific conditions, ensuring harmony in your digital composition.

  • Macros in RUST: Macros are your coding shortcuts, streamlining repetitive tasks. It's like having automated assistants that handle routine work, leaving your coding maestros free for more creative endeavors. Days at sea can be boring. Repetive tasks need to be done but are...ehhh.. boring. To prevent repetition and boilerplate code we know so well from other languages whose named should not be called out aloud.. RUST helps us with extensive declarative and procedural macro's. Meta programming, Matey!

  • Unsafe RUST and when to use it: Consider this your high-performance gear. Unsafe RUST is a power tool, not to be used lightly. It's for those moments when pushing the coding boundaries is necessary, but caution is the keyword.


Alright, savvy business navigators, as we near the end of our RUSTy journey, let's pull out the compass and reflect on our discoveries. Here's a quick recap of the key features and benefits that make RUST a heavyweight in the coding arena.
