This was nasty one to fix and took many days (and nights tbh) but now finally command parsing is fixed and all my tests pass:

https://github.com/puavo-org/tpm2_library/commit/7b0fc824bd341fb21c90a06b945f01feb1c20f5e

There's MS TPM 2.0 emulator and swtpm, and that's like all of command parsing and response synthesis I'm aware of. I.e. by practical means there was no useful existing work to take example of :-) I'm pretty happy and a bit proud too that I've reach unipolarity by writing Rust macros reflecting TCG specifications.

I don't have now known bugs in the protocol crate. I'm sure there's a bunch but still feels nice after 1.5 weeks of sleepless nights and 7K SLOC of code (protocol + cli).

You can literally build identity function with this now :-) And yeah, I can say this with 100% confidence: nothing exactly like this in production usable form pre-exist. It's first of its kind.
