| Of course all software ultimately runs on hardware, which has things like registers and hidden internal state which affect how that hardware accesses or writes to physical memory and all sorts of other "unsafe" things. In a more practical sense, all software, even Python programs, ultimately call C functions that are unsafe. It's like that saying "all abstractions are wrong, some are useful". > what does seeing “written in rust” as a suffix make you think about a project’s qualities before you ever read the code By itself, that tells me very little about a project. Same thing if I see a project written in Python or Go, which are nominally memory safe programming languages.
I perceive a statistically significant likelihood that software written in these languages will not segfault on me, but it's no guarantee.
If I see two programs with the same functionality, where one is written in Python and another one in Rust, I also have some expectation that the one written in Rust will be more performant. But you cannot draw general conclusions from that piece of information alone. However, as a programmer, Rust is a tool that makes it easier for me to write code that will not segfault or cause data races. |
