on a Mac, one can 'brew install qrencode' (from https://fukuchi.org/works/qrencode/index.html.en)

It is possible to use Rust shared objects in C (and other languages) with the "cdylib" or "staticlib" crate types and when the Rust functions are marked with 'extern "C"'. See https://docs.rust-embedded.org/book/interoperability/rust-wi... and https://doc.rust-lang.org/reference/linkage.html. The YouTube video https://www.youtube.com/watch?v=5zmaLhSAkNE has an example/demo and Jon Gjengset has the "Reverse FFI" section in his "Crust of Rust: Build Scripts and Foreign-Function Interfaces (FFI)" video at 2:02:57 https://www.youtube.com/watch?v=pePqWoTnSmQ&t=7378s. Finally, https://prog.world/building-and-using-dynamic-link-libraries... is yes another article on "Building and using dynamic link libraries in Rust".

and also a whitepaper / report from Isovalent on the same topic https://isovalent.com/blog/post/2022-04-oreilly-security can be downloaded for free (after filling the form), or if you have access to O'Reilly's Safari library, it is https://learning.oreilly.com/library/view/security-observabi... there.

the link is wrong - should be https://pingcap.com/blog/why-we-switched-from-bcc-tools-to-l... (the current one points to a WeBank's case study about TiDB)

https://github.com/iovisor/bcc/blob/master/docs/reference_gu... lists the hook points where BPF code can be attached. Also take a look at https://blogs.oracle.com/linux/notes-on-bpf-1 (there are follow-ups - https://blogs.oracle.com/linux/notes-on-bpf-7 has the links at the bottom) and from the Linux source, https://github.com/torvalds/linux/blob/master/include/uapi/l.... https://docs.cilium.io/en/latest/bpf/ is an extensive reference but with an emphasis on the network-related areas (xdp, tc).
