A thread pool for running a number of jobs on a fixed set of worker threads.

Build Status doc.rs


Add this to your Cargo.toml:

threadpool = "1.0"

and this to your crate root:

extern crate threadpool;

Minimal requirements

This crate requires Rust >= 1.13.0

Memory performance

Rust 1.32.0 has switched from jemalloc to the operating systems allocator. While this enables more plattforms for some workloads this means some performance loss.

To regain the performance consider enableing the jemallocator crate.
