I'm a big fan of the Elixir operator, and it should be standard in all functional programming languages. You need it because everything is just a function and you can't do anything like method chaining, because none of the return values have anything like methods. The |> is "just" syntax sugar for a load of nested functions. Whereas the Rust style method chaining doesn't need language support - it's more of a programming style. Note also that it works well in Elixir because it was created at the same time as most of the standard library. That means that the standard library takes the relevant argument in the first position all the time. Very rarely do you need to pipe into the second argument (and you need a lambda or convenience function to make that work).
