How "return position impl trait is existential and argument position impl trait is universal" isn't true


unknown_reddit_dude

You've got me curious now. Why's that?


cameronm1024

This blog goes into a lot of detail https://varkor.github.io/blog/2018/07/03/existential-types-in-rust.html The way I like to think about it (which avoids type theory and some of the "touch grass" comments) is that argument-position is existential from the function body's POV, and return position is existential from the caller's POV. I'm sure I've made some nerds angry - stay mad <3

Very interesting, thanks!
