Crate tokio_schedule

This crate provides a library for scheduling periodic tasks. It is inspired by python’s schedule lib and provides similar API. It is built on tokio (version 1) and chrono lib

Example

use std::error::Error;
use chrono::{Utc, Weekday};
use tokio::spawn;
use tokio_schedule::{every, every_week, Job};

#[tokio::main]
async fn main() -> Result<(), Box<dyn Error>> {
    let weekly = every_week(Weekday::Mon).at(12, 00, 00)
        .in_timezone(&Utc).perform(|| async { println!("Every week job") });
    spawn(weekly);

    let every_30_seconds = every(30).seconds() // by default chrono::Local timezone
        .perform(|| async { println!("Every minute at 00'th and 30'th second") });
    spawn(every_30_seconds);

    let every_30_minutes = every(30).minutes().at(20).in_timezone(&Utc)
        .perform(|| async { println!("Every 30 minutes at 20'th second") });
    spawn(every_30_minutes);

    let every_hour = every(1).hour().at(10, 30).in_timezone(&Utc)
        .perform(|| async { println!("Every hour at :10:30") });
    spawn(every_hour);

    let every_day = every(1).day().at(10, 00, 00)
        .in_timezone(&Utc).perform(|| async { println!("I'm scheduled!") });
    every_day.await;

    Ok(())
}

Timezone

By default all jobs use Local timezone. You can use any timezone that implements chrono::Timezone.

Structs

Every	This is a builder for periodic jobs
EveryDay
EveryDayAt
EveryHour
EveryHourAt
EveryMinute
EveryMinuteAt
EverySecond
EveryWeekDay
EveryWeekDayAt

Traits

Job	This Trait represents job in timezone. It provides method perform.

Functions

every	This function creates Every struct. It is entrypoint for periodic jobs.
every_week	This function creates EveryWeekDay struct. It is entrypoint for weekly jobs.
