Macro signals 

macro_rules! signals {
    [ $(! $tts: tt),* ] => { ... };
    (@ []) => { ... };
    (@ CP) => { ... };
    (@ DBZ) => { ... };
    (@ INEXACT) => { ... };
    (@ INV) => { ... };
    (@ OFW) => { ... };
    (@ ROUND) => { ... };
    (@ SN) => { ... };
    (@ UFW) => { ... };
    (@ [$t:tt]) => { ... };
    (@ [$t:tt, $($tts:tt),*]) => { ... };
}

Macro helper for fast initializing of signals set.

Examples

use fastnum::{*, decimal::*};

let signals = signals![!OFW, !CP];

assert_eq!(signals, Signals::OP_OVERFLOW.combine(Signals::OP_CLAMPED));
