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.

Is there something like "super-safe" rust?
There is also rustig though it seems quite dead.

Is Rust really safe? How to identify functions that can potentially cause panic
There’s the rustig tool (https://github.com/Technolution/rustig) that looks for code paths leading to the panic handler. Not sure if it still works though.

My thoughts on Rust and C++
That's fair. I think I may just be a bit sore that Rustig was allowed to bit-rot and findpanics hasn't seen a commit since 2020.
- What improvements would you like to see in Rust or what design choices do you wish were reconsidered?

Things I hate about Rust, redux
There's Rustig which does it for panics, though it seems unmaintained and uses inspection of the final binary rather than source code/AST inspection.

Three Things Go Needs More Than Generics
> Doesnt Rust have implicit panics on indexing out of bounds?
It does yes. A fair number of other constructs can panic as well.
> I wonder if any codebases lint those away.
Clippy has a lint for indexing so probably.
For the general case, it's almost impossible unless you're working on very low-level software (embedded, probably kernel-rust eventually) e.g. `std` assumes allocations can't fail, so any allocation will show up as a panic path.
https://github.com/Technolution/rustig can actually uncover panic paths, but because of the above the results are quite noisy, and while it's possible to uncover bugs thanks to rustig it requires pretty ridiculous amounts of filtering.

Linus Torvalds on Rust support in kernel
This comment is strongly confused.
> [1] https://github.com/Technolution/rustig
That's a binary analysis tool. It is only approximate, and does not claim to be an accurate analysis like unsafe-checking and typechecking are:
https://github.com/Technolution/rustig#limitations
> All paths leading to panic! from one of those functions (whether actually used or not) will be reported.
It also only works on x86_64 binaries.
Panics are an ugly leftover from the bad old days before Rust had nice monad-like syntax for Result error-handling (the "?" syntax). It's time for panic to sunset.

Is Rust really safe? How to identify functions that can potentially cause panic
Does this or this look so alien that it could never end up in the standard library?
-
Does Rust really abort on allocation failure?
For the benefit of you, OP (/u/sugarcoatedcat) and any passersby, the crowdstrike team found that reserving in a fallible_collections::TryVec is very important... because they implemented the reallocation logic wrong: https://github.com/vcombey/fallible_collections/issues/22

How to deal with out-of-memory conditions in Rust
Wow. TryVec does a realloc call for every single push. TryVec::push is not amortized constant time, it's linear. I've opened an issue: https://github.com/vcombey/fallible_collections/issues/22
