with web framewworks like actix or rocket itsd actually not much different to python flask or nodejs express or .... . but i am a cheap person and prefer to cram as much stuff onto my $4 DO droplets as possible, and rust brings you very far here. might be not a concern for funded startups or big enterprises, but deploying small/mid projects to essentially minimal hardware really makes my wallet happy, plus I essentially never ever had to fix runtime issues, at all, for years. and this was before LLMs were a thing, so handwritten Rust in a fullstack way, at times even WASM frontend SPAs that still kinda just work.
