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.

The Rust Performance Book
1. C compilers don't do a good job, & thus even CPython, which has historically stuck to rather vanilla C, uses computed goto, as described in https://eli.thegreenplace.net/2012/07/12/computed-goto-for-e...
I resorted to similar techniques in optimizing Befunge: https://github.com/serprex/Befunge (See bejit.c & marsh.c/marsh.h)
2. Rust enums are not variable sized, think of them as tagged C unions, where the Rust compiler can sometimes apply tricks to make Option> the same size as Vec
3. match can specialize for straight forward cases, when in doubt use https://godbolt.org

Why asynchronous Rust doesn't work
I've found async to be straight forward anytime I've used it. Promise#then is equivalent to callbacks
async/await often requires very little changes compared to synchronous code, whereas reworking a program into callbacks is much more impactful. & the async/await compilation process tends to produce better performance in addition to this. My first async/await work was a few years ago to increase a data importer's performance by an order of magnitude compared to the blocking code
Here's an example where looping made for a callback that recursively called, using async/await I get to use a plain loop:
before: https://github.com/serprex/Befunge/blob/946ea0024c4d87a1b75d...
after: https://github.com/serprex/Befunge/blob/9677ddddb7a26b7a17dd...
I don't see why people find it so complicated to separate begin-compute & wait-on-compute
I've since rewritten a nodejs game server into rust, https://github.com/serprex/openEtG/tree/master/src/rs/server... handleget/handlews are quite straight forward

Compilers Are Hard
You'll also find them used in CPython's ceval.c
I use them in both my C befunge implementations:

No.
…and this one is no exception -> https://github.com/RustPython/RustPython/issues/1940
Packages that rely on c dependencies like numpy, etc. only work if you write a custom implementation by hand; the “normal” package flat out doesn’t (and cannot) work.

Rust is replacing C as the Python back end
The title would be accurate if this project (https://rustpython.github.io/) was becoming the official version of Python.

Rewrite Sympy in rust
If you absolutely need something comparable to Sympy, then one option might be to figure out how to best call Sympy from Rust. e.g. - RustPython, although it seems like Sympy isn't supported yet - Pyodide, and figuring out how to run it outside of a web browser. Probably also not very easy. - PyPy, and having a pretty simple Python binary for every platform - ...

Our Plan for Python 3.13
I'm actually rooting for RustPython to reach a level of maturity that we'd just be able to ship apis and stuff with it.... https://github.com/RustPython/RustPython

Python 11
Good question and it also actual for: python 3.12, RustPython and xonsh binary.
