Struct trackable::TrackingNumber
[−]
[src]
pub struct TrackingNumber(pub u64);
Randomly generated tracking number.
This is provided to help identifying a tracking target object.
Note that the numbers are generated by rand::random()
function,
thus it is not guaranteed to have strict uniqueness.
Examples
use trackable::TrackingNumber; let n0 = TrackingNumber::generate(); let n1 = TrackingNumber::generate(); // NOTE: The actual values will change every time the below code is executed. assert_ne!(n0, n1); assert_eq!(n0.to_string(), "91fe3f35b6022840"); assert_eq!(n1.to_string(), "3d1a76ec17fb838f");
