๐ Why Rust is the Next Big Thing in Programming ๐ฅ
Rust is redefining what modern programming means. It offers blazing performance, uncompromising safety, and unparalleled concurrency support. Rust is not only winning hearts across the developer communityโitโs transforming industries.
In this comprehensive post, youโll explore everything you need to know about Rust: its advanced features, use cases, why itโs overtaking languages like C++ and Go, and how big tech companies are adopting it. ๐
Whether youโre a systems programmer, backend developer, or a tech enthusiast, this post will provide the high-level knowledge and advanced insights that you wonโt find elsewhere.
Letโs dive in. ๐
๐ฆ 1. What is Rust? A Paradigm Shift in Programming
Rust is a modern systems programming language developed by Mozilla. Itโs designed to be:
- ๐ก๏ธ Safe: Eliminate entire classes of bugs (memory corruption, data races).
- โก Fast: Comparable performance to C and C++ without garbage collection.
- ๐ Concurrent: Safe multi-threading with zero compromises on safety.
Rust represents a paradigm shift in programming, combining:
- The speed of C++.
- The safety of managed languages like Java or Go.
- A modern developer experience with tools like Cargo.
๐ 2. Why Rust is Gaining Massive Popularity
Rust has achieved something extraordinary in a short span:
โ
Most Loved Programming Language: 8 years in a row on Stack Overflow.
โ
Adoption by Industry Leaders: Amazon, Google, Microsoft, and Meta.
โ
Community Growth: Rustโs developer community is doubling year over year.
Key Reasons Behind Rustโs Rise:
- ๐ก๏ธ Memory Safety without Garbage Collection.
- โก Zero-Cost Abstractions: Write high-level code without runtime overhead.
- ๐ Concurrency Without Fear: Safe parallelism made easy.
- ๐ Tooling and Ecosystem: Cargo, Clippy, rustfmt, and more.
๐ก๏ธ 3. The Magic of Rustโs Ownership Model ๐
The ownership system is Rustโs secret sauce. It solves memory management issues at compile-timeโwithout needing garbage collection.
๐ How Ownership Works:
- Every value has a single owner.
- Ownership can be borrowed immutably (
&
) or mutably (&mut
). - Once ownership is transferred, the previous owner loses access.
๐ Why Itโs Revolutionary:
- ๐ซ No Null Pointers: Rust prevents dereferencing invalid memory.
- ๐ก๏ธ No Dangling References: Ensures references are valid for their lifetime.
- ๐ง Compile-Time Guarantees: Bugs are caught before the program runs.
This makes Rust programs both fast and reliable.
๐งฉ 4. How Rust Compares with C++, Go, and Python ๐
Letโs compare Rust to other leading programming languages.
Feature | ๐ฆ Rust | โ๏ธ C++ | ๐ Python | ๐ฅ Go |
---|---|---|---|---|
Memory Safety | โ Compile-Time | ๐ซ Manual, Unsafe | โ GC Managed | โ GC Managed |
Concurrency | โ Safe & Easy | ๐ซ Error-Prone | ๐ก Moderate | โ Built-in Support |
Performance | โ Near Native | โ Native | ๐ซ Slow | โ High Performance |
Tooling | โ Cargo, Clippy | ๐ก Limited | โ Mature | ๐ก Moderate |
Learning Curve | ๐ก Moderate | ๐ซ Steep | โ Easy | โ Easy |
๐ Why Rust Wins:
Rust combines the power of C++ with the simplicity of modern tools. It provides concurrency, safety, and developer ergonomics that other languages canโt match.
๐ 5. Real-World Applications of Rust ๐ฅ

I was planning on learning Rust to start building on Solana, coming from JS/TS background and seeing all these comments, i am doubting my choices :lol
What I noticed (back when I attempted to learn it) is that Rust has a heavy "functional" (FP) feel - yes, it is "mixed paradigm" (imperative and OO and FP), not pure FP, but the whole type system, with "abstract data types", and with its emphasis on "mutable" ('side effects') versus "immutable" reminded me a LOT of a language like Haskell !
While admittedly it's not a pure FP language, you could say that it's by far the most popular current mainstream language that has a heavy "FP feel" to it.
What I like about Rust is that it's unique and innovative, and very well conceived - the memory model (borrowing and so on) is indeed what's unique and what really makes it "special", it's a pretty genius piece of work.
The only serious drawback that I see is its huge learning curve - I think for that reason many companies will still choose GoLang (or just JS/TS) ...
All in all, great to see Rust gaining market share, but I don't see it becoming "dominant" :)
Lots of positive points in the article but there are negatives too, it's good to show them too.
Go and moderate tooling? Bruh!
I get it, it would break your table ๐
If something, Go has less safe type system in comparison to Rust. And ofc GC affects speed.
Meanwhile Python has matured mess. Pyenv, venv, virtualenv, pipenv, pip, conda, poetry,... ๐ Already mess, and we didn't deploy yet. gunicorn, uvicorn, uwsgi, wsgi ...
If eliminating garbage collection is such a nice thing to have, then other languages could start supporting it as well.
The same way as many languages have already copied JavaScriptโs
async/await patternevent loop.And I'll add here this thought:
โ
โค Although obviating the need for a garbage collector is certainly innovative.
You mean copied from C# right? 2011/12 for C# vs 2017 for JavaScript ;-)
I meant to say "event loop", not "async/await" (updated my initial post). The real innovation was the event loop, not async/await. To my knowledge JS was the first to have an event loop, feel free to correct. AFAIK JS didn't copy anything from C#, I think the async/await pattern was the outcome of a collective effort by the programming community of trying to figure out how to program the event loop. If you know who the author of the async/await pattern is, feel free to reply.
The event loop does not really need async/await, Promises are enough for that, although async/await is much nicer to program with.
"copied js async/await"... it's more correct to say that js did the copying ๐
softwareengineering.stackexchange....
I meant to say "event loop", not "async/await". The real innovation was the event loop, not async/await. AFAIK JavaScript was the first language to come up with the event loop concept. Many languages copied the event loop from JS, not the other other way round. Feel free to correct if you have any additional info about that.
I humbly disagree. I compiled zellij today. Took about 15 minutes (minutes!!!!) on my orange pi 5. A behemoth go codebase with at least 10x code that I have compiled within 4.
I remember installing LunarVim too. That too wanted to use some rust tools and compilation is such a pain that I don't wanna deal with Rust if I have to compile anything. I will sacrifice some of that runtime speed to give me some dev speed with go - which is just as safe and almost just as a fast - at least good enough for most usecases anyway.
In a world where people install Electron app, saving 1 millisecond per request is acceptable against that abyssmal compilation speeds.
10+ years and still it is being considered as the next :-)
The learning curve for C++ is the same as rust. You just like the learning curve for rust better. C++ is being pressured by rust to do better with safety, and I think that's great.
One correction with Mozilla and Servo, they originally developed it, but it is now part of the Linux Foundation.
Rust offers native performance. It's typically faster than C++ due to some complexities added on by modern C++ but this really differs based on the context.
