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.

Performance difference between obj.function(...) and function(obj, ...) ?
cargo asm might be useful here (if you can't use godbolt).
-
Is there a simple way to borrow the value of an Option without using a match statement?
They should be inlined in release mode. You'd have to verify by checking the assembly, though, which could be done directly in the Rust playground or with a tool like cargo-asm.

Hey Rustaceans! Got a question? Ask here (4/2023)!
You can use cargo asm - not sure if you can integrate it with VSCode, but even from a terminal it's a pretty convenient tool.

How does rust optimize this code to increase the performance so drastically?
There's probably a built-in one somewhere, but I suspect it'd be easier just to install https://github.com/gnzlbg/cargo-asm
-
Is there a library to display source with annotations?
I don't know if there's a way to do a side by side comparison but cargo-asm uses the source mapping information from rustc to annotate chunks of assembly with it's respective rust code, though it's an imperfect process.

Hey Rustaceans! Got a question? Ask here! (25/2022)!
After that you would need some tools to help figure out how to achieve improvements. That will depend on your system and personal preferences. As the other commenter suggested, perf is a good choice on linux. I personally like to look at the generated assembly, using either cargo asm, godbolt, or just rust playground.

New crate announcement cargo-show-asm
Doesn't this already exist? https://github.com/gnzlbg/cargo-asm
- on the fly disassembler for Rust symbols

Writing the fastest GBDT libary in Rust
From the flamegraph, we knew which function was taking the majority of the time, which we briefly described above. We started by looking at the assembly code it generated to see if there were any opportunities to make it faster. We did this with cargo-asm.

How can I profile this type of slowdown?
You're best bet at the moment is probably using cargo-asm to inspect the function assembly to see when it is performing the correct TCO.
