> their blinky app is like 100KB

I just compiled the blinky example for a cortex m4 board (the example in the rust hal crate for that board, not using any unsafe), and the striped binary is 420 bytes.

So you probably want to review your stence, because you're about 3 orders of magnitude off.

I am currently working with the ATTiny85 and the stripped blinky binary is 275 bytes. I was worried that the ATTiny85 wouldn't have enough flash space (6K) for Rust and now I don't know what to do with all that free space :)

You can use rust on an attiny85? What a time to be alive. I wonder where mine are.

Yes its 420 bytes, which is why I’m commenting as my fingers played me on my thoughts. Do the same for one writer in C++ and report back on the orders of magnitudes… Cheers!
