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

Build Status

extern crate threadpool;

Minimal requirements

This crate requires Rust >= 1.13.0

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 enabling the jemallocator crate.
