I have just done crossfire v2.0.0 release, which provides high-performance spsc/mpsc/mpmc channels.
It supports async context and can be a bridge between async and blocking contexts.
Implemented with lockless in mind, low-level is based on crossbeam-channel.

2 years have passed since Crossfire v1.0.0 release. I reviewed the original API and decided that it needs a complete refactor.
I heard about Flume, which also supports both async and blocking contexts. I once doubted the necessity of continuing the development of Crossfire. Afterwards, I did some benchmarks and found our results still very competitive. As more optimization ideas appeared to me, but first, I have to refactor the API, both for better maintenance and easier for users to remember.
Rewrote tests and added benchmarks; the results are on the project wiki.
