Lessons Learned from Switching from Python to Rust

Performance Comparison: Rust (Actix-Web) vs. Python (FastAPI)Raw Throughput and LatencyOne of the first things that hit me when benchmarking was just how different the performance profiles are between Rust and Python web frameworks. Diesel generates Rust types based on your schema, so mismatched column names or invalid query constructs simply don’t compile. Rust Documentation GenerationRust’s built-in documentation tooling (cargo doc) is phenomenal for code-level docs. ConclusionSwitching from Python to Rust for backend development wasn’t about favoring one language over the other – it was about aligning with our project’s priorities. What changes with Rust is that many issues that would only show up at runtime in Python are instead caught at compile time in Rust, reducing surprises and outages.
