//! # autopool
//!
//! > Warning! **Project in early development!** This is not a stable library.
//!
//! This is an attempt to use a [PID controller](https://en.wikipedia.org/wiki/PID_controller) to drive a worker pool.
//! Most worker pools require you to set a number of workers.
//! However, the right number of workers can change based on environment conditions.
//! `autopool` adds or removes workers to achieve a target throughput.
//!
