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	68253e14ee	Don't suggest restricting bound with unstable traits on stable ... On nightly, we mention the trait is unstable ``` error[E0277]: the trait bound `T: Unstable` is not satisfied --> $DIR/unstable-trait-suggestion.rs:13:9 | LL | foo(t) | --- ^ the trait `Unstable` is not implemented for `T` | | | required by a bound introduced by this call | note: required by a bound in `foo` --> $DIR/unstable-trait-suggestion.rs:9:11 | LL | fn foo<T: Unstable>(_: T) {} | ^^^^^^^^ required by this bound in `foo` help: consider restricting type parameter `T` but it is an `unstable` trait | LL | pub fn demo<T: Unstable>(t: T) { | ++++++++++ ``` On stable, we don't suggest the trait at all ``` error[E0277]: the trait bound `T: Unstable` is not satisfied --> $DIR/unstable-trait-suggestion.rs:13:9 | LL | foo(t) | --- ^ the trait `Unstable` is not implemented for `T` | | | required by a bound introduced by this call | note: required by a bound in `foo` --> $DIR/unstable-trait-suggestion.rs:9:11 | LL | fn foo<T: Unstable>(_: T) {} | ^^^^^^^^ required by this bound in `foo` ```	2024-12-07 21:10:44 +00:00
