The ???? operator (programming.dev)

I found this funny.

The context is as explained by @laund@hachyderm.io

the issue is that you can't return from inside a closure, since the closure might be called later/elsewhere

and this post was the asnwer to the question by @antonok@fosstodon.org

you got me curious what the record for the longest ? operator chain on crates.io is

It make total sense, I just never ran into a Result(Result(Result(T, E), E), E) situation

Edit: Lemmy is so scared of cross site scripting, they simply remove all less than and greater than signs, lmao
