Permits and a thread pool for blocking operations

blocking-permit Rustdoc Travis CI Build MSRV deps status

This crate provides:

  • A specialized, custom thread pool, DispatchPool, for offloading blocking or otherwise long running operations from a main or reactor threads.

  • A BlockingPermit for limiting the number of concurrent blocking operations via a Semaphore type.

MSRV := 1.39.0

The crate will fail fast on any lower rustc (via a version check) and is also CI tested on this version.
