error[E0277]: the trait bound `Box<dyn Map<isize, isize>>: Map<usize, isize>` is not satisfied
--> $DIR/map-types.rs:17:41

LL | let y: Box<dyn Map<usize, isize>> = Box::new(x);
| ^^^^^^^^^^^ the trait `Map<usize, isize>` is not implemented for `Box<dyn Map<isize, isize>>`

= help: the trait `Map<K, V>` is implemented for `HashMap<K, V>`
= note: required for the cast from `Box<dyn Map<isize, isize>>` to the object type `dyn Map<usize, isize>`
error: aborting due to previous error
