Tweak auto trait errors

2025-08-04T17:20:07+00:00

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 {} | -------^^^ | | | 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) { | ^^^^^^ ```

UI tests: add missing diagnostic kinds where possible

2025-04-08T20:06:31+00:00

Trim suggestion parts to the subset that is purely additive

2025-02-14T08:44:10+00:00

Use underline suggestions for purely 'additive' replacements

2025-02-14T08:27:13+00:00

Show diff suggestion format on verbose replacement

``` error[E0610]: `{integer}` is a primitive type and therefore doesn't have fields --> $DIR/attempted-access-non-fatal.rs:7:15 | LL | let _ = 2.l; | ^ | help: if intended to be a floating point literal, consider adding a `0` after the period and a `f64` suffix | LL - let _ = 2.l; LL + let _ = 2.0f64; | ```

Check for generic parameter mismatches on trait functions.

Note for E0599 if shadowed bindings has the method.

implement #123558

Be more lax in `.into_iter()` suggestion when encountering `Iterator` methods on non-`Iterator`

2024-03-03T18:53:36+00:00

``` error[E0599]: no method named `map` found for struct `Vec` in the current scope --> $DIR/vec-on-unimplemented.rs:3:23 | LL | vec![true, false].map(|v| !v).collect::>(); | ^^^ `Vec` is not an iterator | help: call `.into_iter()` first | LL | vec![true, false].into_iter().map(|v| !v).collect::>(); | ++++++++++++ ``` We used to provide some help through `rustc_on_unimplemented` on non-`impl Trait` and non-type-params, but this lets us get rid of some otherwise unnecessary conditions in the annotation on `Iterator`.

Deduplicate some logic and reword output

2024-02-22T18:05:28+00:00

Make confusable suggestions `verbose`
