As a matter of fact, our first implementation of Hurl was written in Python. We switch to Rust because:

- we're a 30 developper team with Linux, Windows and macOs computers. Installing Hurl with Python on Windows boxes was always a challenge and the single drop Rust binary has been a relief for us,

- in a CI, we really want to run tests as fast as possible. The Rust version (the actual one) seems a lot faster that our Python prototype (certainly due to our lack of optimisation in our Python code)
