Rewriting in Rust is usually an exercise in reducing serious security vulnerabilities and memory bugs, not improving speed or stability.
But with LLMs and massive, human-written test suites, rewrites aren’t a bad idea like they used to be. Rust is a perfect target language because it’s compiler is so strict and surfaces issues in a way that’s easy for either humans or LLMs to use.
Something tells me the test suites won't be human written, for most of them. They probably won't be fully human reviewed even.
For existing, mature projects like SQLite, the tests are human-written.
Even if they weren’t, LLMs are pretty good at writing tests because of Github being in their training sets. I rarely find that their tests are bad unless I underspecified what the project is supposed to do.
Disclaimer that I only vibe-code for personal projects, so I haven’t tested this at business scale.
It’s fast, with unparalleled stability, arguably better managed than any other software on earth, deployed on literally everything, so let’s… fork it for street cred?
