scheduled-executor
A simple function scheduler.
The library
This library provides a series of utilities for scheduling and executing tasks (functions and closures). Tasks can be executed at fixed interval or at fixed rates, and can be executed sequentially in the main executor thread or in parallel using a thread pool.
Executors
CoreExecutor
: schedule and execute tasks on a single thread, ideal for short running tasks.ThreadPoolExecutor
: schedule and execute tasks on a thread pool. Can be used for long running tasks.
Task group
The scheduled-executor crate also provides an abstraction for the execution of groups of tasks
called TaskGroup
. A TaskGroup
requires a method for the generation of the collection of
tasks, which will be executed at the beginning of each cycle, and a method for the execution of
individual task, which will be executed for each task.
To see a task group in action, check out the task_group.rs
example.

Examples
Scheduling periodic task is very simple. Here is an example using a thread pool:
// Starts a new thread-pool based executor with 4 threads
let executor = new?;
executor.schedule_fixed_rate;
