Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Tachyonix: a very fast MPSC async bounded channel
Here are a few things that I learned from writing postage that might be helpful: - Poll::Pending can cause subtle deadlock bugs. If a channel endpoint is going to return Poll::Pending, it needs to check conditions, register for notification, and then re-check those conditions before returning Pending. Otherwise, the endpoints could deadlock due to concurrent interactions between the channel state and the notifier. Here's an example fix on an mpsc channel: https://github.com/austinjones/postage-rs/commit/9d2ba3f83dcbbcef83c684462f5efc5b3e7681cc - The single-threaded cases around sender/receiver polls can be covered in unit tests. Tests can verify the poll result, as well as waker interactions. Here's an example: https://github.com/austinjones/postage-rs/blob/main/src/channels/mpsc.rs#L242

The Tokio Upgrade from 0.2 to 1.x
I ran into the same thing with Stream - had tons of code that merged/mapped/filtered channel receivers. I ended up deciding to write an async channel library called postage to replace that functionality.

Announcing Postage, an async channel library
In case anyone is late to the party, I published v0.4.0 with: - a dispatch channel (mpmc queue) - borrow_mut for the watch sender (so you can mutate the value stored in the channel) - .blocking_send() and .blocking_recv() - And a CI matrix, removing the 'beta' tag.

What's everyone working on this week (4/2021)?
I'm working on postage, an async channel library. Postage provides mpsc/broadcast/watch/oneshot channels, as well as Sink and Stream combinators.

pub/sub Event bus in rust
There are pure Rust implementations of the 0MQ protocol. For example: https://github.com/zeromq/zmq.rs

What are the current options for ZMQ, MQTT 5 or other protocols ?
I have used this one, zeromq/zmq.rs and it was pretty okay and it is a native implementation. Though I did not try to implement more complex architectures from RFC like Majordomo, I imagine it would be possible since basic sockets are implemented AFAIK. There is another crate called zmq2, (might have been renamed), it is a more complete implementation or even full maybe, but it provides bindings, so cross-compiling was too much effort, for me at least.

What are some alternatives?
tokio - A runtime for writing reliable asynchronous applications with Rust. Provides I/O, networking, scheduling, timers, ...
zenoh - zenoh unifies data in motion, data in-use, data at rest and computations. It carefully blends traditional pub/sub with geo-distributed storages, queries and computations, while retaining a level of time and space efficiency that is well beyond any of the mainstream stacks.
