I'm in a similar boat, at the very leas an expect can give hits to what happened. However this can also be problematic if your a library developer. Sometimes rust is expected to never panic especially in situations like WASM. This is a major problem for companies like Amazon Prime Video since they run in a WASM context for their TV APP. Any panic crashes everything. Personally I usually just either create a custom error type (preferred) or erase it away with Dyn Box Error (no other option). Random unwraps and expects haunt my dreams.
