Context for actual rust programmers
I was having massive beef with the rust compiler yesterday, every cargo check takes 20 seconds.
And then look at the three functions below, only one of them are Send, if you know why, please let me know.
(Note: value that is not Send cannot be held across an await point, and Box<dyn Error> is not Send)
rs async fn one() { let res: Result<(), Box<dyn Error>> = do_stuff(); if let Err(err) = res { let content = err.to_string(); let _ = do_stuff(content).await; } } async fn two() { let res: Result<(), Box<dyn Error>> = do_stuff(); let content = if let Err(err) = res { Some(err.to_string()) } else { None }; drop(res); if let Some(content) = content { let _ = do_stuff(content).await; } } async fn three() { let content = { let res: Result<(), Box<dyn Error>> = do_stuff(); if let Err(err) = res { Some(err.to_string()) } else { None } }; if let Some(content) = content { let _ = do_stuff(content).await; } }

I get that it’s supposed to be a meme, but aside from the first one these aren’t even rust stereotypes. Is this a meme specifically for people who haven’t used rust, know nothing about rust but have maybe heard that it’s a programming language?
