Do a Crater run with all public *Ext
traits in std
sealed
#80634
Comments
With a bit more context: the "sealed trait" pattern is https://rust-lang.github.io/api-guidelines/future-proofing.html#sealed-traits-protect-against-downstream-implementations-c-sealed and aims to prevent crates other than the one defining a trait from implementing it. This in turns allows adding new method to that trait after it is stable. (Which would otherwise break those external implementations.)
