Function uniffi::lower_into_buffer

pub fn lower_into_buffer<T: ViaFfi>(value: T) -> RustBuffer

A helper function to lower a type by serializing it into a buffer.

For complex types were it's too fiddly or too unsafe to convert them into a special-purpose C-compatible value, you can use this helper function to implement lower() in terms of write() and pass the value as a serialized buffer of bytes.
