Corresponding subsection in async book is not `07.05` not `07.06`. The information on the linked page is the same so it may be reasonable to remove the whole sentence.
This allows retrying binding TCP Socket multiple times. This is useful when using emulators as network might not be available in the beginning. This was orignally implemented in rust-lang#100316 Signed-off-by: Ayush Singh <ayushsingh1325@gmail.com>
Emit a fatal error instead.
The fluent argument syntax is a little special and easy to get wrong, so
we emit a small help message when someone gets it wrong.
Example:
```
parser_mismatched_closing_delimiter = mismatched closing delimiter: `${delimiter}`
```
panics with
```
thread 'rustc' panicked at 'Encountered errors while formatting message for `parser_mismatched_closing_delimiter`
help: Argument `delimiter` exists but was not referenced correctly. Try using `{$delimiter}` instead
attr: `None`
args: `FluentArgs([("delimiter", String("}"))])`
errors: `[ResolverError(Reference(Message { id: "delimiter", attribute: None }))]`', compiler/rustc_errors/src/translation.rs:123:21
```
Do not point at whole statement, only at the expression (skip pointing at `;`)
… `Future::Output` No longer lint against `#[must_use] async fn foo()`. When encountering a statement that awaits on a `Future`, check if the `Future`'s parent item is annotated with `#[must_use]` and emit a lint if so. This effectively makes `must_use` an annotation on the `Future::Output` instead of only the `Future` itself. Fix rust-lang#78149.
… r=tmandry Consider `#[must_use]` annotation on `async fn` as also affecting the `Future::Output` No longer lint against `#[must_use] async fn foo()`. When encountering a statement that awaits on a `Future`, check if the `Future`'s parent item is annotated with `#[must_use]` and emit a lint if so. This effectively makes `must_use` an annotation on the `Future::Output` instead of only the `Future` itself. Fix rust-lang#78149.
`#[test]`: Point at return type if `Termination` bound is unsatisfied Together with rust-lang#103142 (already merged) this fully fixes rust-lang#50291. I don't consider my current solution of changing a few spans “here and there” very clean since the failed obligation is a `FunctionArgumentObligation` and we point at a type instead of a function argument. If you agree with me on this point, I can offer to keep the spans of the existing nodes and instead inject `let _: AssertRetTyIsTermination<$ret_ty>;` (type to be defined in `libtest`) similar to `AssertParamIsEq` etc. used by some built-in derive-macros. I haven't tried that approach yet though and cannot promise that it would actually work out or be “cleaner” for that matter. ```@rustbot``` label A-libtest A-diagnostics r? ```@estebank```
