write_opt consumes WriteBatch

[cvijdea-bd]

Is there any reason why pub fn write_opt(&self, batch: WriteBatch, writeopts: &WriteOptions) takes WriteBatch by value instead of by reference? I could find no references to such a requirement (i.e. write batch becoming invalid after call to write) in the RocksDB documentation.

One use-case for keeping the WriteBatch would be when using opts.set_no_slowdown(true) combined with retries.
