Modern C and What We Can Learn From It - Luca Sas [ ACCU 2021 ]

Yes, that’s a very clean and robust approach. In the “Deferred resource release → Related work” section, one of the links is to a video from the ACCU 2021 conference by Luca Sas titled “Modern C and What We Can Learn From It” that explains modern C techniques, and your one is mentioned at 23′15″: [this video] If you haven’t watched it, I can recommend it.

Modern C by Jens Gustedt is quite good. This video gives a good overview of some modern patterns in C: [this video] I think the best thing you can do is go find a unit testing library you like the look of, maybe some tools for address/leak sanitization, and spend a good amount of time learning CMake and creating a build/project workflow you're happy with. Coming from Rust you've got great tooling and good guardrails in place to keep you on the happy path, I think getting into that groove early in C where you can run experiments and break things in a sane environment is important.
