asynchronous deduplicator with optional LRU caching
If you have "slow", "expensive" or "flaky" tasks for which you'd like to provide de-duplication and, optionally, result caching, then this may be the crate you are looking for.
The crate provides a trait Retriever which should be implemented for your task. Once implemented, you can provide an instance of a Retriever to a Deduplicate which will then handle task de-duplication for you.

This crate build upon the hard work and inspiration of several folks, some of whom I have worked with directly and some from whom I have taken indirect inspiration: - https://github.com/Geal - https://github.com/cecton - https://fasterthanli.me/articles/request-coalescing-in-async-rust - various apollographql router developers
Thanks for the input and good advice. All mistakes/errors are of course mine.
