Why Rust ditched pure functions

Very instructive read! Thanks for sharing.

I am not yet convinced, probably because the response is too short. Can somebody explain the problems with the effect system more detailed? "Eventually people just took to making everything io, at which point it was a noise word and we decided to remove it" this is not happening in haskell, is it the domain rust is used that just doesn't have that can't tolerate much purity?
