License Cargo Documentation Build

A pool-like collection that automatically returns objects to the pool & blocks when the pool is empty

Motivation

I needed something that worked like a pool, that allowed me to checkout objects in the pool & then return them, but it needed to have the following characteristics:

  • It needed to automatically return things to the pool when dropped
  • It needed to have a non-blocking way to do checkout that returned an object or None if all objects are in use
  • IT NEEDED TO ALSO HAVE A BLOCKING CHECKOUT THAT BLOCKS UNTIL THERE IS A USABLE OBJECT

The first two were covered by existing crates:

These are nice crates made by responsible people, & not absurd hacks like this crate.

However, none of them had characteristic three.

So I wrote this thing.
