WebAssembly + Rust: The Speed You Expected

by Jane Doe

A deep dive into leveraging Rust for WebAssembly performance. Learn how to compile Rust to WASM and optimize your workflow for maximum speed.

Why Rust + WebAssembly?

Rust provides memory safety, performance, and zero-cost abstractions while WebAssembly offers portability. Together, they create optimized, secure, and high-performance applications.

Rust Advantages
  • Memeory Safety W/ Ownership
  • High Performance
  • Rich Crate Ecosystem

WebAssembly Advantages

  • Portability
  • Fast Binary Execution
  • Multi-Language Support

Getting Started

1. Install Rust

10 minutes 
                    curl --proto '=https' --location https://sh.rustup.rs -o- | sh

Rustup will install the Rust compiler, Cargo, and other useful tools.

2. Add wasm32-wasi Target

5 minutes

The wasm32-wasi target allows compiling Rust to WebAssembly binaries with WASI support. 

                    
                        rustup target add wasm32-wasi

Code Example

Coming Soon...

Example code snippet will show how to compile a Rust function to WASM

Optimization Techniques

Size Optimization

  • Tree shaking enabled by default
  • Strip debug symbols

Speed Optimization

  • LLVM optimizations
  • Use opt-level flag

Start Building Faster WebAssembly Apps

Rust and WebAssembly together unlock powerful optimizations for modern web applications. Try these techniques and see how they transform your workflow.
