OpenVMM – A New VMM for Windows and Linux, Written in Rust

[flagged]

Due to Rust's safety guarantees there's a perception that software written in Rust is automatically safer than software written in its direct competitors C and C++.

This is not necessarily true, you can write unsafe Rust code and you can write safe C++ code, but it does seem to hold in practice that the guardrails imposed by Rust help quite a bit in stopping devs from making really stupid mistakes.

That would be the "thrustworthiness" implied by the use of Rust.

For myself only, there's also an implication that perhaps the authors are a bit more concerned with safety and security in general. (Don't reply with counterexamples. I know them already. I mean that as a trend, not a solid rule.) That is, the sort of person who might pick Rust for its features might correlate with the sort of person who cares more about those properties in the first place. That doesn't mean they're experts who can execute the ideas flawlessly, or that someone slogging in C couldn't carefully built the same project. I do think it means they're more likely to prioritize safety (yes, it's not 100% safe; yes, you can write insecure code in Rust; don't "correct" me) as an inherent design goal than maybe someone cranking it out in assembler.
