Rust Architecture Reference (2024-2025)
Comprehensive reference for Rust architectural decisions. Use $ARGUMENTS to focus on a specific area, or browse all sections.
Quick Navigation
- For framework/crate selection and comparisons, see frameworks.md
- For design patterns (builder, typestate, newtype, strategy), see design-patterns.md
- For architecture patterns (hexagonal, actors, CQRS, embedded), see architecture.md
- For best practices (error handling, testing, CI, DO/DON'T), see best-practices.md
- For language features (ownership, traits, async, macros, unsafe), see language-features.md
Decision Framework
- Web backend: Default -> Axum. Max throughput -> Actix-web. Batteries-included -> Rocket
- Frontend/WASM: Fine-grained reactivity -> Leptos. Cross-platform -> Dioxus. React-like -> Yew
- Async runtime: Default -> Tokio. Lightweight -> smol. Embedded -> Embassy
- Database: Compile-time SQL -> Diesel. Async + DB verification -> SQLx. ORM-style -> SeaORM
- Serialization: Default -> Serde. Zero-copy perf -> rkyv
- Error handling: Libraries -> thiserror. Applications -> anyhow
- CLI: Always Clap v4.5
Rust in Production
| Company | Result |
|---|
| Cloudflare (Pingora) | 1T+ req/day, 70% less CPU, 67% less memory vs NGINX |
| Discord | ~4x perf vs Go, eliminated GC latency spikes |
| Google (Android) | Memory vulns: 76% -> <20%, 223 -> <50 bugs |
| Microsoft | 36K lines in Windows kernel, goal: eliminate all C/C++ by 2030 |
| AWS (Firecracker) | <125ms boot, <5 MiB memory per microVM |
| Meta (Buck2) | 2x faster builds than Buck1 |
| Figma | 10x faster serialization vs TypeScript |
| Linux kernel | Rust "no longer experimental" (Dec 2025) |
Rust Evolution
| Version | Key Features |
|---|
| 1.75 | Async fn in traits |
| 1.77 | C-string literals (c"hello"), offset_of! |
| 1.79 | Inline const expressions |
| 1.82 | &raw pointers, unsafe extern blocks |
| 1.85 | Edition 2024, async closures, gen reserved |
| 1.88 | Let chains (if let Some(x) = a && cond) |
Edition 2024: async closures, unsafe extern mandatory, Cargo resolver v3, gen keyword reserved.
