Rust Development

Memory safety without garbage collection. Performance without compromise.

The Systems Programming Language for Reliability

Rust brings modern language design to systems programming where C++ and C have dominated for decades. Memory safety is guaranteed at compile-time: no null pointer exceptions, no buffer overflows, no use-after-free bugs. The compiler enforces correct concurrent code through the borrow checker. Yet unlike languages with garbage collection, Rust has zero runtime overhead: no pauses for GC, predictable performance, deployable anywhere.

Rust is blazingly fast: performance rivals C and C++. Compile to WebAssembly for browser-based computation. Embed in Python or Node.js to accelerate bottlenecks. Write command-line tools that ship as single binaries. Build operating system kernels and firmware. Rust is used by companies like Microsoft (Windows components), Amazon (Firecracker), Google (Android), and countless others for performance-critical and security-critical systems.

We use Rust for high-performance systems, WebAssembly applications, backend services requiring extreme reliability, and embedded systems. Rust has a steep learning curve due to the borrow checker, but investment in that learning pays dividends: fewer bugs, faster code, and fearless concurrency. For systems where correctness and performance both matter critically, Rust is unmatched.

Rust Development Services

WebAssembly (WASM)

Compile Rust to WebAssembly for computation in the browser. Image processing, video codecs, machine learning, data analysis: all possible in WASM with near-native performance. Create interactive browser applications that would be impossible with JavaScript alone. Rust WASM bindings provide seamless JavaScript integration.

Use Cases:

  • β€’ Image processing
  • β€’ Cryptography
  • β€’ Video codecs
  • β€’ 3D graphics
  • β€’ Data analysis

Benefits:

  • β€’ Near-native performance
  • β€’ No GC pauses
  • β€’ Small binary size
  • β€’ JavaScript interop
  • β€’ Works offline

Tools:

  • β€’ wasm-bindgen
  • β€’ wasm-pack
  • β€’ wee_alloc
  • β€’ web-sys
  • β€’ js-sys

Embedded Systems & Firmware

Replace C and C++ for embedded development. Memory safety prevents entire classes of bugs. Rust runs on microcontrollers (ARM Cortex, RISC-V, x86) with zero runtime overhead. Build IoT firmware, embedded Linux applications, bare-metal code. Rust enables embedded systems that are both safe and efficient.

Ecosystem: cortex-m for ARM, esp-idf for ESP32, Linux kernel bindings, async embedded runtime with Embassy. Hardware access via HALs without null pointer risks.

High-Performance Backend Systems

Use Rust to build backend systems where performance is critical: real-time systems, financial services, databases, search engines. Actix-web and Tokio provide async runtime supporting thousands of concurrent connections. Compile to a single binary that deploys anywhere. Memory-safe concurrency prevents data races at compile time.

Examples: Tokio runtime, Actix-web framework, Rocket (Rust web framework), async/await syntax, crossbeam for low-level concurrency, parking_lot for efficient synchronization.

System Tools & CLI Applications

Build command-line tools with Rust. Tools written in Rust like ripgrep, bat, exa, and cargo-edit are faster and more reliable than their predecessors. Deploy as single binaries requiring no runtime. Rust excels at system utilities where performance and reliability matter.

Crates: clap for argument parsing, serde for serialization, anyhow for error handling, tokio for async, crossbeam for parallelism, regex for pattern matching.

Rust Frameworks & Runtime

Tokio

Async runtime for Rust. Multi-threaded, high-performance executor supporting thousands of concurrent tasks. Integrate with I/O operations (files, network, timers). The foundation for async Rust applications. Used by major services.

Features:

  • β€’ Multi-threaded runtime
  • β€’ Async I/O
  • β€’ Work-stealing scheduler
  • β€’ Sync & async bridges
  • β€’ Zero-allocation futures

Actix-web

High-performance web framework built on Tokio. Handles thousands of concurrent requests. Routing, middleware, error handling, JSON serialization. One of the fastest web frameworks across any language.

Features:

  • β€’ Type-safe routing
  • β€’ Middleware system
  • β€’ WebSocket support
  • β€’ Extractors & guards
  • β€’ Error handling

Serde

Serialization/deserialization framework. Convert between Rust data structures and formats: JSON, TOML, YAML, MessagePack, etc. Zero-copy deserialization where possible. Essential for APIs and data processing.

Formats:

  • β€’ JSON (serde_json)
  • β€’ TOML (toml)
  • β€’ YAML (serde_yaml)
  • β€’ MessagePack (rmp-serde)
  • β€’ Protocol Buffers

Wasm-bindgen

Bridge between Rust and JavaScript. Export Rust functions to JavaScript, import JS functions into Rust. Automatic type conversions. Essential for WebAssembly projects integrating with browser APIs and JavaScript libraries.

Capabilities:

  • β€’ Function exports
  • β€’ Struct conversion
  • β€’ JS interop
  • β€’ DOM access
  • β€’ Web APIs
