`Diagnostic` has 40 methods that return `&mut Self` and could be considered setters. Four of them have a `set_` prefix. This doesn't seem necessary for a type that implements the builder pattern. This commit removes the `set_` prefixes on those four methods.
It's not used, and doesn't quite fit the general pattern. Also, `Diagnostic::downgrade_to_delayed_bug` doesn't need to return `&mut Self` for the same reason.
- Move comments onto corresponding `Diagnostic` methods. - Make formatting more consistent.
Add the following suggestions:
```
error[E0782]: trait objects must include the `dyn` keyword
--> $DIR/not-on-bare-trait-2021.rs:11:11

LL | fn bar(x: Foo) -> Foo {

help: use a generic type parameter, constrained by the trait `Foo`
|
LL | fn bar<T: Foo>(x: T) -> Foo {

help: you can also use `impl Foo`, but users won't be able to specify the type paramer when calling the `fn`, having to rely exclusively on type inference
|
LL | fn bar(x: impl Foo) -> Foo {
| ++++
help: alternatively, use a trait object to accept any type that implements `Foo`, accessing its methods at runtime using dynamic dispatch

LL | fn bar(x: &dyn Foo) -> Foo {

error[E0782]: trait objects must include the `dyn` keyword
--> $DIR/not-on-bare-trait-2021.rs:11:19
|
LL | fn bar(x: Foo) -> Foo {
| ^^^
|
help: use `impl Foo` to return an opaque type, as long as you return a single underlying type
|
LL | fn bar(x: Foo) -> impl Foo {

help: alternatively, you can return an owned trait object
|
LL | fn bar(x: Foo) -> Box<dyn Foo> {

```
Note the parentheses in the last suggestion:
```
error[E0277]: the size for values of type `(dyn Foo + Send + 'static)` cannot be known at compilation time
--> $DIR/not-on-bare-trait.rs:7:8

LL | fn foo(_x: Foo + Send) {
| ^^ doesn't have a size known at compile-time
|
= help: the trait `Sized` is not implemented for `(dyn Foo + Send + 'static)`
= help: unsized fn params are gated as an unstable feature
help: you can use `impl Trait` as the argument type
|
LL | fn foo(_x: impl Foo + Send) {
| ++++
help: function arguments must have a statically known size, borrowed types always have a known size
|
LL | fn foo(_x: &(Foo + Send)) {
| ++ +
```
…tType` This gets us more accurate suggestions.
`create_almost_fatal` and `emit_almost_fatal` are always used instead.
These are misleading, because the mixture of `Level` and `rustc_errors::Level` makes it look like there are two different types involved.
It has a single call site.
Because it's redundant w.r.t. `Diagnostic::is_lint`, which is present for every diagnostic level. `struct_lint_level_impl` was the only place that set the `Error` field to `true`, and it's also the only place that calls `Diagnostic::is_lint()` to set the `is_lint` field.
It's not used within the repository in any way (e.g. in tests), and doesn't seem useful.
Closes rust-lang#76972 Blocks rust-lang#119452 Approved in rust-lang#119452 (comment)
It appears it was intended to be tier 3, but was accidentally added to tier 2.
No functional changes - all checks have been emitted conditionally on block being rechable already.
Reevaluate `body.should_skip()` after updating the MIR phase to ensure that injected MIR is processed correctly. Update a few custom MIR tests that were ill-formed for the injected phase.
The check attempts to identify potential undefined behaviour, rather than whether MIR is well-formed. It belongs in the lint not validator.
For consistency with other `Emitter` impls, such as `JsonEmitter`, `SilentEmitter`, `SharedEmitter`, etc.
For consistency with other `Emitter` impls.
There are three functions only used for the JSON format.
Normally, each test in `tests/coverage` is automatically run in both `coverage-map` mode and `coverage-run` mode. This new family of directives allows an individual test to specify that it should not be run in a particular mode.
