# Deadpool for synchroneous code [](https://crates.io/crates/deadpool-sync) [](https://github.com/deadpool-rs/deadpool/actions/workflows/deadpool-sync.yml?query=branch%3Amain)  [](https://blog.rust-lang.org/2025/02/20/Rust-1.85.0/)
Deadpool is a dead simple async pool for connections and objects
of any type.
This crates provides helpers for writing pools for objects that don't
support async and need to be run inside a thread.
**Note:** This crate is intended for making the development of
`deadpool-*` crates easier. Other libraries and binary projects
normally should not use this directly and use some provided
reexports by the crates using it.
