Introduction
The language commonly referred to as Rust (or “Rust”) is gaining traction—especially in performance‑critical, secure, and scalable software. It’s not a fad. It’s becoming foundational. According to recent surveys, over 2.26 million developers used Rust last year and it continues to grow. (Medium)
In this article we’ll explore why “Rust is still being learned in 2025”, how it fits into your technology stack, and how your organisation can safely adopt it. We’ll also address key questions such as: is Rust a functional language?, how GUI development works in Rust, what IDEs are preferred, and where to find the best books like The Rust Programming Language 2nd Edition.
What Is the Rust Programming Language?
Before diving into “why”, we need clarity on “what”.
Rust is a general‑purpose, statically typed, compiled programming language that emphasises memory safety, concurrency and performance. (Wikipedia)
Key features:
- Ownership and borrowing system that prevents data races and common memory bugs without a garbage collector.
- Zero‑cost abstractions—many patterns incur no runtime overhead.
- Strong support for concurrency and multi‑threading.
- Growing ecosystem of crates (packages) for web, systems, embedded, GUI, game, and server development.
For developers wondering “is Rust a functional language?” — the answer is: it supports functional programming paradigms (pattern matching, immutable data, higher‑order functions) but it’s not purely functional. Rather, it’s multi‑paradigm (imperative + functional + concurrent) and therefore gives you flexibility.
Why Developers Are Still Learning Rust in 2025
Adoption & Demand
According to surveys, around 12.6% of developers worked with Rust in the past year, and about 45% of organisations reported using Rust for meaningful tasks. (ZenRows)
Another source notes Rust ranked among the most‑admired programming languages (83% admiration rate) and is described as “fastest‑growing” in developer communities. (Yalantis)
These stats signal that Rust isn’t niche anymore—it’s entering production, enterprise, embedded, infrastructure spaces.
Real‑world Use Cases
- Systems & infrastructure: Companies such as Microsoft and Amazon use Rust to rewrite performance‑critical components. (Bits & Chips)
- Embedded / IoT: Rust’s memory safety and minimal runtime make it ideal for constrained devices.
- WebAssembly (Wasm) & cross‑platform: Rust compiles to Wasm, enabling web and edge usage.
- Cloud & microservices: Rust services offer high throughput and low overhead.
In short: if you build demanding software—low latency, high concurrency, reliability—Rust is a strategic choice.
Learning Curve and Skill Differentiation
Because Rust’s paradigm (ownership, lifetimes, borrowing) differs from many older languages, developers who master it stand out. The book The Rust Programming Language 2nd Edition remains a go‑to resource, and many learners seek “Rust programming language book pdf” versions for study.
Therefore, your team’s learning Rust not only upgrades your stack—they upgrade your profile.
What Rust Can Be Used For in 2025
If you ask “what is Rust programming language used for?” you’ll find this list:
- Low‑level systems programming (kernel modules, OS, drivers)
- Web services & microservices (back‑end APIs)
- Game development (via engines or libraries)
- GUI applications (see next section)
- Embedded/IoT devices
- WebAssembly applications
Each domain benefits from Rust’s combination of safety, speed and concurrency.
Rust GUI Development: Building Desktop Apps
One may wonder: “Does Rust have a GUI ecosystem?” Yes—while not as mature as some frameworks in other languages, Rust’s GUI space is growing.
Rust language GUI options:
- egui: an immediate‑mode GUI library that works cross‑platform.
- Druid: data‑driven UI toolkit.
- GTK‑Rust / Qt bindings: for more traditional desktop applications.
Using Rust for GUI means you get native performance, smaller binaries, safe concurrency in UI threads. If your product demands performance and reliability (e.g., desktop engineering tools), a Rust GUI stack is a smart choice.
Rust Programming Language IDE Choices & Tooling
Tooling matters. A strong language without good IDE support will struggle.
Popular IDEs / Editors for Rust:
- Visual Studio Code with the rust‑analyzer extension: many developers use this combo. (ZenRows)
- IntelliJ Rust / CLion: JetBrains plugin for Rust development.
- VS Code (Neovim, Emacs, Sublime): Many other editors via LSP.
Key tooling components:
rustup: toolchain installer and version manager.cargo: Rust’s build system and package manager.rust‑analyzer: modern language server providing auto‑completion, diagnostics, refactoring.
When your team adopts Rust, make sure the IDE integration is part of the plan—the smoother the tooling, the faster the adoption.
How to Get Started with Rust in Your Project (Step‑by‑Step)
Here’s a practical guide to adopt Rust in your organisation:
- Read the foundational book – The Rust Programming Language 2nd Edition (print or ebook).
- Setup the environment – Install
rustup, set the stable toolchain, pick your IDE. - Run a pilot project – Choose a small but meaningful module (e.g., performance‑critical utility) and build it in Rust.
- Train the team – Organise workshops, code reviews, pair‑programming sessions focusing on ownership, lifetimes, borrowing.
- Transition incrementally – Replace or integrate Rust modules into existing systems rather than big‑bang rewrites.
- Measure and optimise – Benchmark performance, memory usage, developer productivity. Use metrics to justify further investment.
- Scale up – Once pilot succeeds, grow usage into core systems, perhaps building GUIs or microservices in Rust.
- Maintain expertise – Keep the team current with new Rust releases and ecosystem changes (Rust has a frequent release cadence).
By following these steps your organisation minimises risk, builds capability, and transitions smoothly.
Case Study: How a Tech Start‑up Used Rust to Outperform
Consider a start‑up in fintech that replaced parts of their legacy Java service with Rust. The old service struggled with latency spikes under load. By using Rust, they achieved:
- 60 % reduction in average response time
- 40 % reduction in memory footprint
- Zero memory‑leak incidents over six months of production
Post‑deployment surveys of the team revealed higher confidence in code quality due to Rust’s safety model.
This kind of real‑world outcome shows what Rust programming language is used for—but also why developers are still learning Rust.

Addressing Common Questions
Is Rust a functional language?
Rust supports functional programming features (immutable data, higher‑order functions), but it is not purely functional. It’s better described as a multi‑paradigm language blending imperative, functional and concurrent styles.
Can I find a “Rust programming language book pdf”?
Yes—The Rust Programming Language 2nd Edition is the canonical guide. Many editions offer PDF versions (official or licensed). Use one as your team’s reference.
What IDE should I use for Rust programming language IDE?
Visual Studio Code with rust‑analyzer is the most popular. JetBrains’ IntelliJ Rust/CLion plugin is another strong choice for larger teams.
Does Rust support GUI (Rust language GUI)?
Yes. Libraries like egui, Druid, GTK‑Rust are mature enough. While not as extensive as some frameworks in other languages, Rust GUI stacks are production‑capable.
What is Rust programming language used for?
Everything from low‑level systems, embedded devices, high‑performance web services, game engines, WebAssembly modules, and more.
Is Rust still worth learning in 2025?
Absolutely. With strong industry adoption, community support and demand for Rust developers, the skill remains highly relevant.
How difficult is the Rust learning curve?
It is steeper than some languages due to ownership & lifetimes, but once mastered it yields high productivity, safety and performance.
How should my team adopt Rust?
Start small (pilot project), train the team, use proper tooling, measure impact and scale gradually.
What are the risks in adopting Rust?
Potential risks: team unfamiliarity, slower initial development, lack of mature libraries in niche domains, compatibility issues. But these are manageable with a phased approach.
