Do you use #rustlang hyper/h2 at scale? Would you be able to easily try out a performance run using a PR that is meant to significantly reduce contention with multi-threaded HTTP/2? It would be a big help! github.com/hyperium/h2/...

To put it another way: if the official position of the Android and Linux kernel teams is “we, some of the world’s best coders, can’t safely use C” then the bar under CRA’s requirements of “safe by design” should be nearly impossible to meet for mere mortals when using C.

After setting up an initial strict #rustlang Clippy config for hyper, I wrote up some mentored instructions if you'd like to get involved contributing. There's a bunch of lints that need to be considered, many are easy. github.com/hyperium/hyp...

2026 isn't even half way done, and so far we've received over double the security reports from the entire previous year (which already was more than normal).

So I was curious and tried clippy with pedantic and restriction turned on. 479 warnings. Oh ok, like what? Single function call. Implicit return. Default trait method. Missing inline on public methods. 🤔
