error[E0038]: the trait `Bar` cannot be made into an object
|
|
--> $DIR/issue-18959.rs:11:12
|
|
|
|
|
LL | fn foo(b: &dyn Bar) {
|
|
| ^^^^^^^ `Bar` 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-18959.rs:1:20
|
|
|
|
|
LL | pub trait Foo { fn foo<T>(&self, ext_thing: &T); }
|
|
| ^^^ ...because method `foo` has generic type parameters
|
|
LL | pub trait Bar: Foo { }
|
|
| --- this trait cannot be made into an object...
|
|
= help: consider moving `foo` to another trait
