Use non-2015 edition paths in tests that do not test for their resolution

2025-06-03T08:13:33+00:00

This allows for testing these tests on editions other than 2015

Add test for issue 125668

Do not suggest using `-Zmacro-backtrace` for builtin macros

2025-03-14T19:50:03+00:00

For macros that are implemented on the compiler, we do *not* mention the `-Zmacro-backtrace` flag. This includes `derive`s and standard macros.

Remove detail from label/note that is already available in other note

2024-10-29T16:26:57+00:00

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> = IsCopy { t: None }; | ^^^^^^^^^^^^^^^^^^^^^^^ the trait `Copy` is not implemented for `NotCopy` | = note: required for `Option` to implement `Copy` note: required by a bound in `IsCopy` --> $DIR/wf-static-type.rs:7:17 | LL | struct IsCopy { 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> = IsCopy { t: None }; | ^^^^^^^^^^^^^^^^^^^^^^^ the trait `Copy` is not implemented for `NotCopy`, which is required by `Option: Copy` | = note: required for `Option` to implement `Copy` note: required by a bound in `IsCopy` --> $DIR/wf-static-type.rs:7:17 | LL | struct IsCopy { t: T } | ^^^^ required by this bound in `IsCopy` ```

Suggest inline const blocks for array initialization

[AUTO-GENERATED] Migrate ui tests from `//` to `//@` directives

Provide more context on derived obligation error primary label

2024-01-30T21:28:18+00:00

Expand the primary span of E0277 when the immediate unmet bound is not what the user wrote: ``` error[E0277]: the trait bound `i32: Bar` is not satisfied --> f100.rs:6:6 | 6 | ::foo(); | ^^^ the trait `Bar` is not implemented for `i32`, which is required by `i32: Foo` | help: this trait has no implementations, consider adding one --> f100.rs:2:1 | 2 | trait Bar {} | ^^^^^^^^^ note: required for `i32` to implement `Foo` --> f100.rs:3:14 | 3 | impl Foo for T {} | --- ^^^ ^ | | | unsatisfied trait bound introduced here ``` Fix #40120.
