Passing integers around is easy, sharing structs or strings and context pointers for use in callbacks crossing the language barrier etc is typically much harder.

For rust code calling C, sharing structs is doable with #[repr(C)]. See https://doc.rust-lang.org/reference/type-layout.html#reprc-s...

(Nitpick: I don’t think it technically is correct to call this “The C representation”, as strict layout in C depends on the C compiler/ABI. I wouldn’t trust this to be good enough for serializing data between 32-bit and 64-bit systems, for example. For calling code on the same system, it’s good enough, though)
