This is a (hopefully) maintained rust project that unsafely exposes the cpp driver at https://github.com/datastax/cpp-driver/ in a somewhat-sane crate.
You can use it from cargo with [dependencies.cql_ffi] git = "https://github.com/tupshin/cql-ffi"
There are still a few bugs, but you will definitely want to use https://github.com/tupshin/cql-ffi-safe instead
