We already use these throughout the compiler and have been using them as needed when users find cases where the output is verbose. This is a proactive search of some cases to use `short_string`. We add support for shortening the path of "trait path only". Every manual use of `short_string` is a bright marker that that error should be using structured diagnostics instead (as they have proper handling of long types without the maintainer having to think abou tthem). When we don't actually print out a shortened type we don't need the "use `--verbose`" note. On E0599 show type identity to avoid expanding the receiver's generic parameters. Unify wording on `long_ty_path` everywhere. 2025-08-07T10:49:36+00:00 Stuart Cook Zalathar@users.noreply.github.com 2025-08-07T10:49:36+00:00 urn:sha1:bcd50fd45fb92a6c96af7e91893488bd4499153c Tweak auto trait errors Make suggestions to remove params and super traits verbose and make spans more accurate. ``` error[E0567]: auto traits cannot have generic parameters --> $DIR/auto-trait-validation.rs:6:19 | LL | auto trait Generic<T> {} | -------^^^ | | | auto trait cannot have generic parameters error[E0568]: auto traits cannot have super traits or lifetime bounds --> $DIR/auto-trait-validation.rs:8:20 | LL | auto trait Bound : Copy {} | ----- ^^^^ | | | auto traits cannot have super traits or lifetime bounds ``` ``` error[E0380]: auto traits cannot have associated items --> $DIR/issue-23080.rs:5:8 | LL | unsafe auto trait Trait { | ----- auto traits cannot have associated items LL | fn method(&self) { | ^^^^^^ ``` 2025-08-04T20:43:53+00:00 Oneirical manchot@videotron.ca 2025-07-13T20:25:27+00:00 urn:sha1:7196d8cd661b875401126a81641d2effc40b3d85 2025-08-04T17:20:07+00:00 Esteban Küber esteban@kuber.com.ar 2025-02-28T23:37:37+00:00 urn:sha1:91e606b715ac4e8f59fac86d42ec2ad23f4ef169 Make suggestions to remove params and super traits tool-only, and make the suggestion span more accurate. ``` error[E0567]: auto traits cannot have generic parameters --> $DIR/auto-trait-validation.rs:6:19 | LL | auto trait Generic<T> {} | -------^^^ | | | auto trait cannot have generic parameters error[E0568]: auto traits cannot have super traits or lifetime bounds --> $DIR/auto-trait-validation.rs:8:20 | LL | auto trait Bound : Copy {} | ----- ^^^^ | | | auto traits cannot have super traits or lifetime bounds ``` ``` error[E0380]: auto traits cannot have associated items --> $DIR/issue-23080.rs:5:8 | LL | unsafe auto trait Trait { | ----- auto traits cannot have associated items LL | fn method(&self) { | ^^^^^^ ``` 2025-07-24T21:01:44+00:00 Oneirical manchot@videotron.ca 2025-07-13T19:56:27+00:00 urn:sha1:a924d44115b632775ef0d2e12382e285953b0c2c 2025-07-17T11:26:39+00:00 codedump lichuang1982@gmail.com 2025-07-16T15:21:47+00:00 urn:sha1:f2048019718409885ac57c480f010bdfbfe5bfd0 2025-06-30T08:45:43+00:00 Oli Scherer github333195615777966@oli-obk.de 2025-06-04T11:32:29+00:00 urn:sha1:28f023c75194fdd61b12b64a33e7e0ba877eb3c9 2025-06-29T10:29:55+00:00 Guillaume Gomez guillaume1.gomez@gmail.com 2025-06-29T10:29:55+00:00 urn:sha1:05b209d3a2f398c834cd9ecbe5eb095a49c26f02 `tests/ui`: A New Order [12/N] Some `tests/ui/` housekeeping, to trim down number of tests directly under `tests/ui/`.
