From: src/test/compile-fail/E0446.rs E0446 needs a span_label, updating it from: ``` error[E0446]: private type in public interface --> src/test/compile-fail/E0446.rs:14:21 | 14 | pub fn bar() -> Bar { //~ ERROR E0446 | ^^^ ``` To: ``` error[E0446]: private type in public interface --> src/test/compile-fail/E0446.rs:14:21 | 14 | pub fn bar() -> Bar { //~ ERROR E0446 | ^^^ private type can't be public ```
