⏱️ A task scheduling library written in Rust
- cron (0.12.1)
- chrono (0.4.38)
- time (0.3.36)
- log (0.4.21)
In your Cargo.toml
add:
[dependencies]
tasklet = "0.1.5"

use log::{error, info};
use simple_logger::SimpleLogger;
use tasklet::{TaskBuilder, TaskScheduler};
/// A simple example of a task with two step,
/// that might work or fail some times.
fn main() {
// Init the logger.
SimpleLogger::new().init().unwrap();
// A variable to be passed in the task.
let mut exec_count = 0;
// Task scheduler with 1000ms loop frequency.
let mut scheduler = TaskScheduler::default(chrono::Local);
// Create a task with 2 steps and add it to the scheduler.
// The second step fails every second execution.
// Append the task to the scheduler.
scheduler.add_task(
TaskBuilder::new(chrono::Local)
.every("1 * * * * * *")
.description("A simple task")
.add_step(None, || {
info!("Hello from step 1");
Ok(()) // Let the scheduler know this step was a success.
})
.add_step(None, move || {
if exec_count % 2 == 0 {
error!("Oh no this step failed!");
exec_count += 1;
Err(()) // Indicate that this step was a fail.
} else {
info!("Hello from step 2");
exec_count += 1;
Ok(()) // Indicate that this step was a success.
}
})
.build(),
);
// Execute the scheduler.
scheduler.run();
