Why do you choose Rust？

In my opinion，the C language is the best choice to write a Reis Module，many other Redis modules are written by C language ，why do you choose Rust?
It's just my question, maybe you are good at Rust, it' wonderful too.

Hi Ben,

It is an interesting question.

The module was indeed started in C, and I was using several tools to ensure correctness of the code, lack of memory leaks and so on.

This was working just enough, however when I introduced multithread I started to witness several bugs that crashed the whole application making it unusable, I tried really hard to debug it but without success.

Finally I gave up and I rewrote it in Rust.

Valgrind wasn't needed anymore, the code is automatically formatted and I don't experience anymore multithread bugs.

A life saver.

Granted, I am not an expert in C, but Rust allowed me to write this module with confidence!
