error[E0038]: the trait `Qux` is not dyn compatible
--> $DIR/taint-const-eval.rs:11:33
|
LL | static FOO: &(dyn Qux + Sync) = "desc";
| ^^^^^^ `Qux` is not dyn compatible
|
note: for a trait to be dyn compatible it needs to allow building a vtable
for more information, visit <https://doc.rust-lang.org/reference/items/traits.html#dyn-compatibility>
--> $DIR/taint-const-eval.rs:8:8
|
LL | trait Qux {
| --- this trait is not dyn compatible...
LL | fn bar();
| ^^^ ...because associated function `bar` has no `self` parameter
= note: required for the cast from `&'static str` to `&'static (dyn Qux + Sync + 'static)`
help: consider turning `bar` into a method by giving it a `&self` argument
|
LL | fn bar(&self);
| +++++
help: alternatively, consider constraining `bar` so it does not apply to trait objects
|
LL | fn bar() where Self: Sized;
