Rust WASM Optimization

Overview

This skill covers optimization techniques for Rust code compiled to WebAssembly, including binary size reduction, runtime performance improvements, and build configuration.

Build Configuration

Cargo.toml Profiles

[profile.release]
opt-level = "z"        # Optimize for size
lto = "thin"           # Thin LTO for faster builds
codegen-units = 1      # Single codegen unit for better optimization
panic = "abort"        # Smaller binary (no unwinding)
