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.

Rust std:fs slower than Python
> I wish Rust would switch to mimalloc or the latest tcmalloc (not the one in gperftools).
That's nonsensical. Rust uses the system allocators for compatibility, not because they're good (they were not when Rust switched away from jemalloc, and they aren't now).
If you want to use mimalloc in your rust programs, you can just set it as global allocator, that takes all of three lines: https://github.com/purpleprotocol/mimalloc_rust#usage

Hey Rustaceans! Got a question? Ask here (15/2023)!
Context: When using mimalloc as global allocator, linking with crt-static fails with the following error:

Tips on scaling a monolithic Rust web server?
Use an optimized memory allocator, my choice is mimalloc. It wins every time I compare it, even against jemalloc (not to mention it supports arena hardening which is good for security).

Rust Mimalloc v0.1.30 has just been released!
Version 0.1.19 of the Rust wrapper for the mimalloc memory allocator has just been released!

Maintenance status (jemallocator)
I'll mention that mimalloc (+ Rust wrapper) is great alternative to jemalloc.

Rust: Box Is a Unique Type
If you have an object that's !Unpin, then Miri will not apply uniqueness rules to anything containing it [0], including boxes and &mut references. (In the example code, replacing the PhantomPinned with a () will make Miri complain again.) This is considered a temporary (if long-lived) measure to allow async executors to manipulate pinned futures without invalidating all their references and whatnot. Thus, it might be seen as undetected UB, in lieu of a permanent solution.

Fivefold Slower Compared to Go? Optimizing Rust's Protobuf Decoding Performance
That would be true if you used `Vec::clear` too, it doesn't allocate a new vector. My point was that you still end up running Drop implementations with RepeatedField, just not all at once. See https://play.rust-lang.org/?version=stable&mode=debug&editio...

Borrow Checking Without Lifetimes
Self-referential structs work fine in Rust and always have.
https://play.rust-lang.org/?version=stable&mode=debug&editio...
The compiler will correctly prevent you from moving the value.
The other way to have a struct that starts out as non-self-referential and then becomes self-referential can be achieved with `unsafe` and `Pin::new_unchecked`, which is how `async {}` is handled.

On the other hand, both this wrapper and yours are counterproductive if the element size is dynamic (e.g. perhaps you're dealing with some nonsense like:)

New Linux glibc flaw lets attackers get root on major distros
Overflow checks turn into two's compliments' wrapping, but that's only considered acceptable because bounds checks are not turned off.

Atomics and Concurrency
I have no idea what you're talking about, but it sounds unnecessarily complicated and why I don't use Rust for any serious work.
This demonstrates the ABA problem in safe Rust: https://play.rust-lang.org/?version=stable&mode=debug&editio...
Substitute the sleep with a combination of doing computation/work and the OS thread scheduler, and you can see how the bug surfaces.
