Generate as “plain old data” and add to allowlist. Generate Rust bindings for the given C++ type such that it can be passed and owned by value in Rust. This only works for C++ types which have trivial move constructors and no destructor - you’ll encounter a compile error otherwise. If your type doesn’t match that description, use generate instead, and own the type using UniquePtr. A directive to be included inside include_cpp - see include_cpp for general information.
