Language

Rust

A systems language that delivers C-level performance with memory safety guaranteed at compile time.

Overview

Rust is a systems programming language focused on performance, reliability and memory safety. Its defining feature is the ownership and borrow checker — a compile-time system that prevents whole categories of bugs (use-after-free, data races, null dereferences) without a garbage collector.

That combination makes Rust ideal for high-throughput, low-latency services where you cannot afford GC pauses or memory corruption. It has a steeper learning curve than most languages, but the code that compiles tends to be fast and correct.

What it is

Rust gives you manual-memory-level performance with automatic safety enforced by the compiler. No garbage collector, no runtime overhead, but also no segfaults or data races in safe code. Its async story (Tokio) makes it strong for concurrent network services.

  • Ownership/borrow checker — memory safety without a GC
  • Fearless concurrency; data races caught at compile time
  • Tokio + Actix for high-performance async services

When we reach for it

We use Rust for the hot paths: high-volume crawling, parsing, and anything where per-request latency and predictable memory use actually matter. When Node would spend too long in one busy loop, Rust is the answer.

Trade-offs

Rust is harder to learn and slower to write than TypeScript or Python — the borrow checker fights you until it clicks, and compile times are longer. It is overkill for CRUD apps. We reserve it for performance-critical infrastructure, not everyday application code.

How REO Rank uses it

Our distributed enterprise web crawler is a Rust workspace built on Actix-Web and Tokio, backed by MongoDB and Redis Streams. Rust lets it crawl at scale with tight, predictable resource use — work we would not trust to a garbage-collected runtime.

Common questions

Rust — questions

Straight answers on how this fits your marketing and build.

For performance-critical, concurrent work. Rust runs near C speed with no garbage-collector pauses and catches memory and data-race bugs at compile time. Node and Python are faster to write but hit CPU and latency ceilings that Rust does not.
