> I don't see a good way now to avoid these copies, apart from waiting for improvements in the rust standard library itself (https://github.com/rust-lang/rfcs/blob/master/text/2930-read-buf.md#summary). One thing we maybe could do (that woudl be more invasive) would be to add a template parameter to `read_buffer` with the relevant underlying native type to ensure alignment. So instead of `read_buffer` it would be something like `read_buffer<i32>` and `read_buffer<i64>` This would ensure the correct underlying buffer alignment but would take some non trivial changes (e.g. move away from usng ArrowData and instead create the various arrays directly (e.g. PrimtiveArray::new())` -- This is an automated message from the Apache Git Service.
