From: GitLab CI Runner <trini@konsulko.com> So far ulib only supports linking against C programs. While this is the common case, there is no particular reason why other languages could not be used to write the main program, so long as they can interoperate with the libu-boot.so/.a library. Rust provides a Foreign Function Interface feature, which makes it possible to declare and call C functions from Rust code. It provides memory safety without the uncertainty of garbage collection and with less overhead. It would be nice if ulib could be used with Rust. This series provides the necessary pieces to make this work. It adds an example program which works just like the C one, but written in Rust. As with the existing example, the program can be built against the static ulib or can use dynamic linking. Note that only sandbox is supported at present, i.e. native execution on (for example) a Linux machine. Future work will add support for running on other architectures. In order to make more use of ulib features, U-Boot's headers will need to be made available in Rust format. For now, only a very few are provided, as a starting point.
