"How do you find the speed of the Rust version of your FEC vs, the C version?"
translates from "Australian" to "English" as:
"What is the speed of the Rust version of your FEC vs, the C version?
Though it was interesting to know how you do it. I'm interested in the speed, as I once looked into using Rust for a signal processing project, but ultimately went with C++ because the team wasn't familiar with Rust. At the time, it seemed to me that Rust had the potential to go faster.
