Michael Goulet	c29838843b	Report impl has stricter requirements even when RPITIT inference gets in the way	2025-01-03 02:45:29 +00:00
Esteban Küber	65a54a7f27	Tweak multispan rendering ... Consider comments and bare delimiters the same as an "empty line" for purposes of hiding rendered code output of long multispans. This results in more aggressive shortening of rendered output without losing too much context, specially in `*.stderr` tests that have "hidden" comments.	2024-12-12 23:36:27 +00:00
Esteban Küber	d860e5b088	Mention type parameter in more cases and don't suggest ~const bound already there	2024-12-07 21:37:13 +00:00
Esteban Küber	3f2a63a68b	Use trait name instead of full constraint in suggestion message ... ``` help: consider restricting type parameter `T` with traits `Copy` and `Trait` | LL | fn duplicate_custom<T: Copy + Trait>(t: S<T>) -> (S<T>, S<T>) { | ++++++++++++++ ``` ``` help: consider restricting type parameter `V` with trait `Copy` | LL | fn index<'a, K, V: std::marker::Copy>(map: &'a HashMap<K, V>, k: K) -> &'a V { | +++++++++++++++++++ ```	2024-12-07 21:29:58 +00:00
Esteban Küber	d13c34828e	reword trait bound suggestion message to include the bounds	2024-12-07 21:26:20 +00:00
Esteban Küber	5b54286640	Remove detail from label/note that is already available in other note ... Remove the "which is required by `{root_obligation}`" post-script in "the trait `X` is not implemented for `Y`" explanation in E0277. This information is already conveyed in the notes explaining requirements, making it redundant while making the text (particularly in labels) harder to read. ``` error[E0277]: the trait bound `NotCopy: Copy` is not satisfied --> $DIR/wf-static-type.rs:10:13 | LL | static FOO: IsCopy<Option<NotCopy>> = IsCopy { t: None }; | ^^^^^^^^^^^^^^^^^^^^^^^ the trait `Copy` is not implemented for `NotCopy` | = note: required for `Option<NotCopy>` to implement `Copy` note: required by a bound in `IsCopy` --> $DIR/wf-static-type.rs:7:17 | LL | struct IsCopy<T:Copy> { t: T } | ^^^^ required by this bound in `IsCopy` ``` vs the prior ``` error[E0277]: the trait bound `NotCopy: Copy` is not satisfied --> $DIR/wf-static-type.rs:10:13 | LL | static FOO: IsCopy<Option<NotCopy>> = IsCopy { t: None }; | ^^^^^^^^^^^^^^^^^^^^^^^ the trait `Copy` is not implemented for `NotCopy`, which is required by `Option<NotCopy>: Copy` | = note: required for `Option<NotCopy>` to implement `Copy` note: required by a bound in `IsCopy` --> $DIR/wf-static-type.rs:7:17 | LL | struct IsCopy<T:Copy> { t: T } | ^^^^ required by this bound in `IsCopy` ```	2024-10-29 16:26:57 +00:00
