error[E0038]: the trait `Fetcher` cannot be made into an object
--> $DIR/issue-102762.rs:18:21
|
LL | fn get<'a>(self: &'a Box<Self>) -> Pin<Box<dyn Future<Output = Vec<u8>> + 'a>>
| ------------- help: consider changing method `get`'s `self` parameter to be `&self`: `&Self`
...
LL | fn fetcher() -> Box<dyn Fetcher> {
| ^^^^^^^^^^^ `Fetcher` cannot be made into an object

note: for a trait to be "object safe" it needs to allow building a vtable to allow the call to be resolvable dynamically; for more information visit <https://doc.rust-lang.org/reference/items/traits.html#object-safety>
