error[E0038]: the trait `Map` cannot be made into an object
|

--> $DIR/issue-26056.rs:20:13
|
|
|
|
|
LL | as &dyn Map<Key=u32,MapValue=u32>;
|
|
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ `Map` 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>

LL | trait Map: MapLookup<<Self as Map>::Key> {
|
|
| --- ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ...because it uses `Self` as a type parameter
|
|
| |
|
|
| this trait cannot be made into an object...
