When we built our edge computing runtime, we evaluated several languages and ultimately chose Rust. Here is why.
Performance
Rust delivers C-level performance without garbage collection pauses. For an edge runtime where every millisecond matters, this was crucial.
Safety
Memory safety is critical when running untrusted code. Rust memory safety guarantees at compile time, eliminating entire classes of vulnerabilities.
Developer Experience
Despite its reputation, Rust has excellent tooling. Cargo makes dependency management a breeze, and the compiler error messages are incredibly helpful.
The Results
- Sub-millisecond cold starts
- 50% less memory usage vs V8
- Zero memory-related security issues
- Predictable performance under load
