no, it's just clickbait.

- Rust is huge, many options, many programming styles

- typical Rust project has lots of transitive dependencies

- there is nothing in Rust that disallows using system libraries or linking to them

- it's not even true that the program is going to be mem-safe because there could still be unsafe {} either in the repo, or in any of the transitive deps. not to say that safety is broader than just mem-safety.

if you think "written in Rust" says anything, I'd argue that you might give it a try and find out yourself. I did that, and I am glad I am out. the reason why I am telling you is because I've been click-baited (into Rust) before, and it took me few years to realize all of this, and to make a move.
