Section I - library

lib.rs

We will also declare these dependencies in our share src/lib.rs library with macros in use.

#[macro_use] extern crate serde_derive;
#[macro_use] extern crate serde_json;

We also need to provide a share function get_unix_now() that teh daas module will need. So we declare the use of the dependencies and the function itself.

use std::str;
use std::time::{SystemTime};

fn get_unix_now() -> u64 {
    match SystemTime::now().duration_since(SystemTime::UNIX_EPOCH) {
        Ok(n) =>n.as_secs(),
        Err(_) => panic!("SystemTime before UNIX EPOCH!"),
    }
}

To add the daas module to our library, we declare it at the bottom of our src/lib.rs file, (after the hello_world module).

pub mod daas;
