Extension of FuSa proven Slint

Functional safety (FuSa) is a core requirement in domains like automotive industry, the medical sector, and aerospace. For safety-critical systems often certifications for entire solutions are part of the regulatory requirements before a solution may be deployed, including all free and open source components which are part of such a solution. The entire solution often also includes graphical user interface elements as well, meaning of course that any underlying frameworks for developing GUIs need to be functional-safety-proven to even be considered.

Slint is a versatile declarative UI solution written in Rust. Rust's strong guarantees of memory safety and thread safety make it a suitable language for developing applications that require Functional Safety (FuSa) certification. This project completes the effort to make Slint compliant with the requirements for certification, offering a compelling option for building robust graphical user interfaces requiring functional safety.
