rdkafka-sys error: the trait `Copy` may not be implemented for this type

I encountered this error when building the master branch. It seems a bindgen issue is relevant.

error[E0204]: the trait `Copy` may not be implemented for this type

FYI @jerry73204 I've managed to fix this by bumping bindgen from 0.49.2 to 0.51.1 in rdkafka-sys/Cargo.toml.

Good work. It fixes this issue. Besides, @sd2k could you remove the = version prefix for futures-review in your Cargo.toml? That conflicts with update-to-date tokio.

@jerry73204 I guess you meant in the std-future branch; just pushed an update without the = version pin.
