Developing an Async FFI Framework for Rust and C# Interoperability

The ScyllaDB driver team has developed a new Async FFI framework to enable effective communication between Rust and C#. This framework aims to build other drivers on top of the Rust driver, overcoming the limitations of existing solutions. Notably, it leverages new features on the C# side, such as the UnmanagedCallersOnly attribute, to facilitate asynchronous calls between the two languages.
