Matthias Krüger ffdb471872 Rollup merge of #117914 - estebank:issue-85843, r=wesleywiser ... On borrow return type, suggest borrowing from arg or owned return type When we encounter a function with a return type that has an anonymous lifetime with no argument to borrow from, besides suggesting the `'static` lifetime we now also suggest changing the arguments to be borrows or changing the return type to be an owned type. ``` error[E0106]: missing lifetime specifier --> $DIR/variadic-ffi-6.rs:7:6 | LL | ) -> &usize { | ^ expected named lifetime parameter | = help: this function's return type contains a borrowed value, but there is no value for it to be borrowed from help: consider using the `'static` lifetime, but this is uncommon unless you're returning a borrowed value from a `const` or a `static` | LL | ) -> &'static usize { | +++++++ help: instead, you are more likely to want to change one of the arguments to be borrowed... | LL | x: &usize, | + help: ...or alternatively, to want to return an owned value | LL - ) -> &usize { LL + ) -> usize { | ``` Fix #85843.		2023-12-12 17:40:53 +01:00
