The Case for Rust
Rust gives you C-level performance with memory safety guarantees. No garbage collector, no null pointer exceptions, no data races. For services that need to be reliable and fast, it's hard to beat.
Performance That Matters
A Rust API server typically uses 10-50MB of RAM compared to 100-500MB for equivalent Node.js or Python services. Under load, the difference is even more dramatic.
- Lower latency (no GC pauses)
- Better resource utilization
- Handle more concurrent connections
- Cheaper to run at scale
Safety Without Runtime Cost
Rust's compiler catches bugs before they reach production:
- No null pointer dereferences
- No buffer overflows
- No data races in concurrent code
- No use-after-free bugs
The compiler is strict, but it saves hours of debugging in production.
The Ecosystem
Actix-web is our framework of choice:
- One of the fastest web frameworks in any language
- Async by default with Tokio
- Type-safe request handling
- Great middleware ecosystem
The Learning Curve
Yes, Rust has a learning curve. The borrow checker will fight you at first. But:
- Most concepts click after 2-3 weeks
- The compiler messages are actually helpful
- Once it compiles, it usually works
- The community is incredibly welcoming
When NOT to Use Rust
Rust isn't always the right choice:
- Quick prototypes (use Python/Node)
- Scripts and automation (use Python/Bash)
- When your team doesn't know it yet
- When time-to-market is critical
We use Rust for long-lived services that need reliability. For everything else, we pick the right tool for the job.
Real World Example
The NortherCodes platform API is written in Rust:
- Handles Git HTTP protocol
- Processes file uploads with malware scanning
- Serves API requests with sub-millisecond latency
- Runs on a small VPS with plenty of headroom
