Rust 开发速度与性能优化痛点

原话

I'm finding the bottleneck writing Rust code to be that compiling and running tests is too slow compared to TypeScript - which is unfortunate, because I want all of the guarantees of Rust - I just don't particularly care if it runs at the fastest speed possible - at least not at the prototype stage, or ever for a lot of what I'm doing (though I do want the guarantees regardless). I wish it could run interpreted to massively speed up development, and that it had a Mull-like mutant testing framework so that mutants didn't take hours and tens-to-hundreds of gigabytes of space.

If it can be measured, then LLMs can optimize it. Once I had repo commands that could dump `sample` results and a cpu profiler/trace and then a benchmark tool that let me A/B/ABBA-test the current modified git workspace against HEAD or any commit, the LLMs could just do their thing.

I've been having great results with this kind of thing. I find that really just need a sensible framework within which the optimization can take place. Essentially just providing the measurement harness, and some sort of motivation for what I'm doing... Eventually, it will have gone through the whole list with me, while having documented all the measurements along the way.
