• -1: Serialize within the same process.
• 1: retain enumerations, allow serialization of timespan and timestamp: Useful for passing data between threads
• 2: unenumerate, allow serialization of timespan and timestamp
• 3: unenumerate, compress, allow serialization of timespan and timestamp

use kdbplus::api::*;
use kdbplus::api::native::*;

#[no_mangle]
pub extern "C" fn conceal(object: K)->K{
  unsafe{b9(3, object)}
}
