The HN title still doesn't include it, so I certainly didn't open it because of it. The GitHub repository, however, includes it in the project name, so I thought my question was not inappropriate.
I'm certainly not out to disparage Rust in any way, merely looking to compare my experiences with other computational researchers. While language choice is in many ways subjective and we should all pick the ones we like, I've learned a lot in the past from discussions about the subject.
Hello, author here - The choice to use rust mainly came from the fact I have more experience with it than with C++. Also, the compiler makes it really easy to write good code.
This, along with really simple testing, benchmarking and the ease of adding dependencies (through crates) made it a good choice. There are almost no downsides from using rust, provided you have experience with it!
