You work on tiny hardware.

And shout out to Vegard as well.

It was an amazing episode too.

Now, Rust has fallible allocations for vectors nowadays, but...

I'm guessing that you even want to avoid allocations in the first place, especially the dynamic allocations.

And Oxide, for example, has a scheduler called Hubris.

And Steve, please correct me if I'm wrong here, but Steve Klapnick, that is.

I think what they did was they used static allocation, static memory, and every payload that they run on that scheduler has a fixed size known at compile time, which allows you to have predictable allocations.

Do you use that pattern as well, if you can?

So having a fixed struct and knowing that only this struct will need to be allocated, quote unquote, on the stack?

If I understand correctly, that means you don't initialize the struct.

You have a view into this byte block in this block of bytes and zero copy kind of makes it safe for you.

well that's really nice it's a nice example of making illegal state impossible to represent and parsing instead of validating that's kind of cool you said that zero copy is a bit like a safe transmute would that mean you can ditch transmute altogether and always use zero copy or are there any cases where zero copy just doesn't provide a safe interface

Okay, you try to minimize unsafe code.

Do you also try to minimize unwraps?

Are there any better patterns that you use?

In my mind, you learned Rust in hardcore mode.

It's in the space industry as a startup, straight out of university with a Python background, and then also needing to ship features really early on, you know, working there.

What would you recommend others to do on how to learn Rust effectively, learn it quickly, learn it well?

How would you flatten the learning curve?
