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
Oh, I have written my own share of userspace C context switching libraries, I know all the gory the details :). For example see my minimalist [1] stackful coroutine library: the full context switching logic is three inline asm instructions (99% of the complexity in that code is to transparently support throwing exceptions across coroutine boundaries with no overhead in the happy path).
You need compiler help for the custom calling convention support and possibly to optimize away the context switching overhead for stackful coroutines, which is something that compilers can already do for stackless coroutines.
The duff device is just a way to simulate stackless coroutines (i.e. async/await or whateverer) in plain C, in a way that the compiler can still optimize quite well.

Declarative, non-intrusive, compile-time C++ reflection for audio plug-ins
Using gcc extended asm you can pass literal constants to the asm and they will be expanded textually (or at least their address will). I don't think the details are fully documented anywhere and I had to use intel syntax to make it work, but it might be possible even wit AT&T syntax.
Take a look a this[1] for example. See how trampoline, the destructor and the size are passed in with the 'i' constraint and are referred to their value with the %cX constraint (yes, the code is write only and even with a lot of comments I have only the most vague idea of what I was trying to do here).
Probably more work is require for PIC though.

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.

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.
