Incorrect span / broken rustfix: help: use dyn: dyn #[dom_struct] (original) (raw)

One of the many new (or newly enabled by default) warnings in Servo in today’s Nightly:

warning: trait objects without an explicit dyn are deprecated --> components/script/dom/window.rs:169:1 | 169 | #[dom_struct] | ^^^^^^^^^^^^^ help: use dyn: dyn #[dom_struct]

The suggestion is wrong, which means cargo fix also fails and therefore does not apply fixes for (the many) other warnings where the suggestion is correct.

warning: failed to automatically apply fixes suggested by rustc to crate script

after fixes were automatically applied the compiler reported errors within these files:

This likely indicates a bug in either rustc or cargo itself, and we would appreciate a bug report! You're likely to see a number of compiler warnings after this message which cargo attempted to fix but failed. If you could open an issue at https://github.com/rust-lang/rust/issues quoting the full output of this command we'd be very appreciative! Note that you may be able to make some more progress in the near-term fixing code with the --broken-code flag

The following errors were reported: error: expected item, found keyword dyn --> components/script/dom/dedicatedworkerglobalscope.rs:164:1 | 164 | dyn #[dom_struct] | ^^^ expected item

error: aborting due to previous error

Original diagnostics will follow.
