error[E0277]: the trait bound `NonLeakS: bounds_check::LeakTr` is not satisfied
|

--> $DIR/maybe-bounds-in-dyn-traits.rs:65:26
|
|
|
|
|
LL | let _: &dyn LeakTr = &NonLeakS;
|
|
| ^^^^^^^^^ unsatisfied trait bound
|
|

help: the trait `bounds_check::LeakTr` is not implemented for `NonLeakS`

LL | struct NonLeakS;

|
| ^^^^^^^^^^^^^^^

error[E0038]: the trait `DynCompatCheck2` is not dyn compatible
|
|
--> $DIR/maybe-bounds-in-dyn-traits.rs:90:17

|
|
|
|
LL | fn mut_foo(&mut self) {}
|
|
| --------- help: consider changing method `mut_foo`'s `self` parameter to be `&self`: `&Self`
|
|
...
|
|
LL | let _: &dyn DynCompatCheck2 = &NonLeakS;
|
|
| ^^^^^^^^^^^^^^^ `DynCompatCheck2` is not dyn compatible
|
|
|
|
|
note: for a trait to be dyn compatible it needs to allow building a vtable

|
LL | trait DynCompatCheck2: ?Leak {
|
|
| --------------- this trait is not dyn compatible...
|
|
LL | fn mut_foo(&mut self) {}
|
|
| ^^^^^^^^^ ...because method `mut_foo`'s `self` parameter cannot be dispatched on
|
|
= help: only type `NonLeakS` implements `DynCompatCheck2`; consider using it directly instead.
