Crate janus_client

A DAP client

This library implements the client role of the DAP-PPM protocol. It uploads measurements to two DAP aggregator servers which in turn compute a statistical aggregate over data from many clients, while preserving the privacy of each client’s data.

Examples

use url::Url;
use prio::vdaf::prio3::Prio3Histogram;
use janus_messages::{Duration, TaskId};
use std::str::FromStr;

#[tokio::main]
async fn main() {
    let leader_url = Url::parse("https://leader.example.com/").unwrap();
    let helper_url = Url::parse("https://helper.example.com/").unwrap();
    let vdaf = Prio3Histogram::new_histogram(
        2,
        12,
        4
    ).unwrap();
    let taskid = "rc0jgm1MHH6Q7fcI4ZdNUxas9DAYLcJFK5CL7xUl-gU";
    let task = TaskId::from_str(taskid).unwrap();

    let client = janus_client::Client::new(
        task,
        leader_url,
        helper_url,
        Duration::from_seconds(300),
        vdaf
    )
    .await
    .unwrap();
    client.upload(&5).await.unwrap();
}
