Struct trackable::TrackingNumber

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");
