Hey there.
If you want to run shared memory serviceworkers in wasm, such as for wasm_bingden_rayon, wasm_threads etc, then the above is required (in addition to enabling features).
However, while I understand the std argument easily enough from the documentation, I have even after long seraching not really been able to nail down what the panic_abort does.
I mean, obviously, the name is a hint. But is panic_abort a crate in rust-src, or where is that name specified? How precisely does this influence things (will that abort just in the std crate or also for my own panics?) And are there alternatives/where would I find these?
