Lazy Pool

Build Status

A lazy-initialized object pool. Provides a sharable pool where objects are initialized on demand. The pool works by providing Futures which allow for usage with async/await (untested) and threading as well.

See tests for examples of usage

Release Notes

2.0.0

  • Reworked most of the package to make it async-first. Having the factory methods being synchronous would force switching from async - to sync - to async which didn't work in many cases. The interface changed significantly.
  • Locking is now using async-aware mutexes.
  • Releasing objects back to the pool needs to be done outside of Drop (until AsyncDrop becomes a thing). Introduced a get macro to be used as the main means of acquiring and using an item.

1.1.0

  • Allow marking an object as tainted through the Pooled wrapper. This drops the item from the pool instead of releasing it.

1.0.0

  • Migrate to std futures.

0.2.3

  • Introduce mutable dereferencing

0.2.1

  • Minor fixes and switch to VecDeque

0.2.0

  • Deprecated all previous version due to misusing Future trait
  • Allow definition of a factory using closures. This adds the overhead of needing a box for function references as well
