error[E0038]: the trait `Qiz` cannot be made into an object
--> $DIR/issue-19380.rs:11:29
|
LL | foos: &'static [&'static (dyn Qiz + 'static)]
| ^^^^^^^^^^^^^^^^^ `Qiz` 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>
--> $DIR/issue-19380.rs:2:6

LL | trait Qiz {
| --- this trait cannot be made into an object...
LL | fn qiz();
| ^^^ ...because associated function `qiz` has no `self` parameter
= help: only type `Foo` implements the trait, consider using it directly instead
help: consider turning `qiz` into a method by giving it a `&self` argument

LL | fn qiz(&self);
| +++++
help: alternatively, consider constraining `qiz` so it does not apply to trait objects
