Is there a demand for no_std feature?

[Laura7089]

I'd find that useful!

I would also find this useful. Happy to put some of my time towards it as well, but I could use some direction.

If effort is put into no_std support, please make sure no_alloc and heapless is a part of that solution :)

[sureshjoshi]

Are there any Rust protobufs that are heapless/noalloc? Basically, the nanopb equivalent?

I'm investigating just embedding nanopb into my embedded app at this point.

[nathaniel-brough]

I believe tokio/prost supports nostd

[sureshjoshi]

Yep, they do support no_std. I was testing it out the other day.

They do require alloc though.

My (hopefully temporary) solution is to create nanopb bindings using bindgen and so far, so good 🤷🏽

A first party, Rust-native, heapless would be much nicer though.
