I think it’s clear what stack is typically meant by “an Electron app” and why using a blanket term like this is faster.

However, you could use Rust compiled to WASM in an Electron app, therefore the two aren’t even mutually exclusive.

For the OP's specified case, it is only a little language related. It is more a lib/framework related thing.

Tauri is the thing being implicitly compared with electron. Well worth checking out.

It's not, both can be apps.
