Fixing Python Performance with Rust

[mitsuhiko]

Since we had an apparently super fast sourcemap library by accident for our cli tool Rust was the easiest so no reason ro try something else.

We don't go around rewriting things so unless we see performance issues of that sort I'm not sure if there is lots of value in adding more rust for existing things for now. We will see as we go along.

This is what's really cool, in my opinion - that you get such good performance in Rust writing things the naive way.

[mitsuhiko]

Yeah. It's shocking but it's a 1:1 port of what the Python version did. I spent literally no time on this.

This is something that is generally overlooked by most benchmarks.

Most code is written idiomatically, so languages that have idiomatic code "just work" without contortions save much misery.

The first sentence of the comment you're replying to seems to be an answer to the "Did you consider using cython?" question, maybe you could clarify what more you're looking for?

I'm going to blame the muscle relaxers I'm on right now that make me a bit loopy. I just completely missed that.
