It's already in use at least it automotive. If you are not working with safety critical systems (ADAS type) Rust and to some extent embassy is already in the wild. Companies like ETAS (https://www.etas.com/ww/en/) or Ferrous (https://ferrous-systems.com) are working to certify Rust and some crates (embassy is there) to be used with safety critical components. It's not question if but when it will be used. Volvo, Renault and some Chinese brands already ship cars with Rust embedded components in non safety critical path.

Do you have any (soft) evidences, that actually embassy is used in safety-critical applications? I think that is quite more difficult to qualify the whole of embassy with the HAL, executor and the other components used. Ferrous is just the qualified toolchain incl. core std. and some other libraries. Additionally a question is how well it integrates e.g. with ARM self-test libraries for the platform safety.

I know that sonair [0] is actually using Rust in the safety critical path. Toyota Woven [1] is for now just using it in infotainment and non-safety applications.

I am closely monitoring the space, as I am currently evaluating to use Rust and potentially embassy for a safety-critical embedded product myself. I hope to this way also contribute to safety-critical Rust usage. If anyone has further information or just wants to exchange ideas, I'd be super happy to!

A handful of companies participated in this. It seems they all are working already with it or working towards it: https://rustfoundation.org/media/announcing-the-safety-criti...
