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.

Monoio – A thread-per-core Rust async runtime with io_uring
> Have any other Rust async runtimes use io_uring/gotten at all good yet?
yes, check out `actix-rt`

Weird architectures weren't supported to begin with
> For example, this method violates memory safety by handing out multiple mutable references to the same data, which can lead to e.g. a use-after-free vulnerability. I have reported the issue to the maintainers, but they have refused to investigate it. _(issue now deleted)_

Having trouble using async libraries
It has been tokio and v1 support is in progress on master branch: https://github.com/actix/actix-net/blob/master/actix-rt/Cargo.toml

What's the canonical way of doing it in rust?
Was playing around with mio (https://github.com/tokio-rs/mio) (not that mio itself is very important here!) and was trying to implement a simple something that I've done in java before: a Reactor that you can register ReactorClients with that will get callback whenever there are events on the corresponding socket etc.

RFC: A non-blocking networking library for Rust
How does it compare to mio?

How does the Rust mio crate implement deregistering connections?
TcpStream gets its wake behavior by delegating to the fd wakers. The Unix wakers have a few implementations, for different platforms. On Linux and Android, epoll is used.

Looking for Tokio's event loop source code
The real implementation details of the I/O event queue is done in mio as u/hniksic pointed out, but that's more comparable with libuv which is certainly a huge part of the Node runtime. mio and libuv have a lot of similarities (at least they used to).

Python multi-level break and continue
My example was "twice by one developer", not "twice across all indexed repos."
A spot check shows that quite a few in your link are used specifically to ensure correct handling of Rust multi-level breaks work syntax, like https://github.com/rust-lang/rust-analyzer/blob/master/crate... , https://github.com/rust-lang/rustfmt/blob/master/tests/sourc... , https://github.com/rust-lang/rust/blob/master/src/tools/rust... , https://github.com/rust-lang/rust/blob/master/src/tools/rust... and likely more.
Another is a translation of BASIC code to Rust, using break as a form of goto. https://github.com/coding-horror/basic-computer-games/blob/e...
The example at https://github.com/tokio-rs/mio/blob/master/tests/tcp.rs is a nice one
// Wait for our TCP stream to connect

Crates to help with event-loop type pattern?
In my program, I have about 6 different components that follow the pattern below. Basically, the components run a thread while polling on crossbeam channels, file descriptors or sockets. For polling, I am using Mio (https://github.com/tokio-rs/mio).

Ask HN: Has any Rust developer moved to embedded device programming?
On the code side it's pretty much the same as C++. You have a module that defines an interface and per-platform implementations that are included depending on a "configuration conditional checks" #[cfg(target_os = "linux")] macro.

What is the point of async and await?
Indeed! In practice it's done through the polling operation: instead of a separate poll for op1 and op2, the program essentially tells the OS "wake me when either op1 or op2 is ready" (through the epoll syscall on Linux). The mio crate implements this, and the example on the readme is basically the same loop, but written with this polling strategy in mind.
