Enter Maestro, a unix-like monolithic kernel that aims to be compatible with Linux in order to ensure wide compatibility. Interestingly, it is written in Rust. It includes Solfége, a boot system and daemon manager, maestro-utils, which is a collection of system utility commands, and blimp, a package manager. According to Luc, it’s creator, the following third-party software has been tested and is working on the OS: musl (C standard library), bash, Some GNU coreutils commands such as ls, cat, mkdir, rm, rmdir, uname, whoami, etc… neofetch (a patched version, since the original neofetch does not know about the OS). If you want to test it out, fire up a VM with at least 1 GB of ram.
not exactly, as there are rust compilers like mrust that don’t actually have borrow checkers and virtually none of those safety checks actually occur and there is a question of if the gcc rust compiler would be implementing that feature into the compiler.
So, that would be an attribution failure; as it isn’t required by the language but the most popular rust compiler does include that feature.
But yes, more compilers would likely benefit the languages they support by also adopting that feature by default.
Borrow checking is part of the language specification, and a compiler that does not include it is, by definition, incomplete. The authors of mrust even state this in the project README.
Your claim is roughly equivalent to saying a C compiler which does not produce an error when a program calls an undeclared function means that C as a language does not ensure that your code doesn’t call functions that don’t exist - i.e., nonsense at worst, and irrelevant at best.
