Starting from a working example is always a good idea :) then once things start breaking you might have a clue why.

Have no experience with iced but interesting. Can you share a minimal example of what you’d like to do? At least the source code of Sandbox reads fn view(&self).

True. As an outsider I can only speculate what is going on there. As you say, other BigTech-financed projects seem fine.

About big tech companies sponsoring projects: The have an interest that Rust is maintained and many people write good crates which they can use. But they don’t care so much about the world being able to profit from the ecosystem. If they do, then just because this is actually profitable for themselves.

I think this turns into a problem once a project get mainstream. Let’s imagine that in twenty years Rust largely replaced C/C++. It would become part of the worlds critical infrastructure. I don’t think it is good to let the monopolies have the governance. I don’t believe that they act in interest of people. Often it may appear the way. But if it does, I’m convinced that there’s usually a business interest behind. For example, screwing people completely would be bad for business or might trigger the attention of regulation bodies. So they don’t do it. Screwing people very gently such that they get used to it before they notice might happen. Slowly boiling the frog. This type of companies do that on a daily basis.

Alone the sponsors of the Rust Foundation I find very questionable (Amazon, Google, Huawei, Meta, Microsoft, https://foundation.rust-lang.org/ on the bottom). Unfortunately, corporatism is what you get from corporations. Happy to hear about the crab-lang fork.
