protocol: parse MsgType using scroll

Open hdhoang opened this issue 7 years ago • 4 comments

As a PoC it only parses one byte. Next up would be buffer.pread::<Message>(0), but I haven't cooked up a multiplexing try_from_ctx for the different MsgType + XOp yet.

Further, we could have buffer.pwrite::<LedTheme> for sending the 0xca set-LED messages too.

Oh that's really nice, I had been looking for a lib that does exactly this but hadn't tried out scroll yet. This is looking really promising, especially that it does proper parsing rather than just casting and hoping it all works.

I'd like to make some round-trip tests to run on x86-64 too.

The test target hard-codes linux-gnu though, I will try to extract rustup target list|grep default | cut -d ' ' -f 1 into make somehow.
