hash: String

The identifying hash of the Marker

previous_hash: String

The identifying hash of the previous Marker in the Data Tracker Chain

Methods

impl Marker

pub fn new(
    idx: usize,
    tmstp: u64,
    act_id: String,
    dat_id: String,
    prev_hash: String
) -> Marker

Constructs a Marker object

Arguments

• idx: usize - The sequanece number of the Marker in the Data Tracker Chain, (e.g.: 0,1,2,3).
  
• tmstp: String - The date and time (Unix timestamp) the data came into posession of the Actor.
  
• act_id: String - The Unix Epoch time when the DUA was agreed to.
  
• dat_id: String - The unique identifier of the the data being tracked.
  
• prev_hash: String - The identifying hash of the previous Marker in the Data Tracker Chain
  

#Example

extern crate pbd;

use pbd::dtc::Marker;

fn main() {
    let marker = Marker::new(1, 1578071239, "notifier~billing~receipt~email".to_string(), "order~clothing~iStore~15150".to_string(), "123456".to_string());
     
    println!("{} has touched the data object {}", marker.identifier.actor_id, marker.identifier.data_id);
}

pub fn genesis(dat_id: String) -> Marker

Constructs the first Marker (a.k.a. Genesis Black)

Arguments

• dat_id: String - The unique identifier of the the data being tracked.
  

#Example

extern crate pbd;

use pbd::dtc::Marker;

fn main() {
    let marker = Marker::genesis("order~clothing~iStore~15150".to_string());
     
    assert_eq!(marker.identifier.index, 0);
}

pub fn serialize(&self) -> String

Serializes the Marker.

#Example

extern crate pbd;

use pbd::dtc::Marker;

fn main() {
    let marker = Marker::new(1, 1578071239, "notifier~billing~receipt~email".to_string(), "order~clothing~iStore~15150".to_string(), "hash-12345".to_string());
     
    println!("{}", marker.serialize());
}
