A small project but something that I'm happy about: Postgresql backed persistent queues crate for Rust.
I couldn't find any crate that would be ergonomic enough to use and provide features I deem essential, i.e. retryability, scheduling, poison job detection, barriers, backoff strategies etc.
it's an area I'm familiar with so after spending 2 days trying to integrate external libs I decided to roll my own and I'm quite happy how it turned out in 2 days of development.
I plan to open-source it in the near future but right now using it in my another project and it's running quite well.
