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

I’m writing my Rust wrong… I have match statements everywhere to the degree that it’s cluttering up everything.
If all you do in the Err(e) => ... match arm is returning the error, then you absolutely should use the ? operator instead.
If the match arm also converts the error type into another error type, implement the From trait for the conversion, then you can use ? as well.
If you want to add more information to the error, you can use .map_err(...)?. Or, if you’re using the anyhow crate, .with_context(...)?.
