*/2 1-8,11 * * *

A Full Example

Scheduler is a cron time shceduler.
The example below will show you:
* Parse CronEntry.
* Make a output keeper to capture cron outputs. * Make a scheduler.
* Make a task, and then start it, it will spawn and excute new job periodically.

` extern crate time; extern crate cron_rs;

use std::thread; use std::time as stdtime; use std::process::Command;

use cronrs::Scheduler; use cronrs::Job; use cronrs::Server; use cronrs::OutputKeeper; use cronrs::CronEntry; use cronrs::Task;

fn main() { // Make a time scheduler let tm = time::now(); let sch = Scheduler::new("*/2 1-4,16,11,17 * * *").unwrap(); println!("{:?}", sch); println!("{:?} {}", &tm, sch.isTimeUp(&tm));

// Parse cron string to CronEntry
let cronEntry = r#"{"intervals":"* * * * *","command":"date +%F_%T","description":"print time every minute","daemon":false,"testRun":true,"timeoutSeconds":5,"autokill":true,"alarmEmail":false,"alarmSms":true,"alarmUsers":"gaobushuang","id":1,"cronId":1,"treeId":261,"treePath":"b2c.b2cop.build-ci.build-ci.cn-test","active":false,"updateTime":"2017-02-07T13:22:52+08:00","lastCode":0,"lastJob":0,"watch":true,"host":""}"#
    .parse::<CronEntry>().unwrap();

// Make time scheduler
let intervals = &*cronEntry.intervals.to_owned();
let sch = Scheduler::new(intervals).unwrap();

// Make a new server and a output keeper,
// then waiting for incoming message.
let srv = Server {
    output_keeper: "foo".to_string(),
};
let mut keeper = OutputKeeper::new(&srv);

// Make a new task
let mut mytask = Task::new(sch, cronEntry, &keeper);

// mytask spawn a new job and execute it every minute.
mytask.start();
