error: lifetime may not live long enough
--> f205.rs:8:16
|
7 | fn resolve_symbolic_reference(&self, reference: Option<Reference>) -> Option<Reference> {
| - --------- has type `Option<Reference<'1>>`
| |
| let's call the lifetime of this reference `'2`
8 | return reference;
| ^^^^^^^^^ method was supposed to return data with lifetime `'2` but it is returning data with lifetime `'1`
|
help: consider introducing a named lifetime parameter
|
7 | fn resolve_symbolic_reference<'a>(&'a self, reference: Option<Reference<'a>>) -> Option<Reference<'a>> {
| ++++ ++ ++++ ++++
```
The correct suggestion would be
```
help: consider introducing a named lifetime parameter
|
7 | fn resolve_symbolic_reference<'a>(&self, reference: Option<Reference<'a>>) -> Option<Reference<'a>> {
| ++++ ++++ ++++
```
but we are not doing the analysis to detect that yet. If we constrain `&'a self`, then the return type with a borrow will implicitly take its lifetime from `'a`, it is better to make it explicit in the suggestion, in case that `&self` *doesn't* need to be `'a`, but the return does.
