error[E0495]: cannot infer an appropriate lifetime for lifetime parameter `'b` due to conflicting requirements
--> $DIR/trait-impl-of-supertrait-has-wrong-lifetime-parameters.rs:24:13
|
LL | impl<'a,'b> T2<'a, 'b> for S<'a, 'b> {
| ^^^^^^^^^^
|
note: first, the lifetime cannot outlive the lifetime 'a as defined on the impl at 24:6...
--> $DIR/trait-impl-of-supertrait-has-wrong-lifetime-parameters.rs:24:6

LL | impl<'a,'b> T2<'a, 'b> for S<'a, 'b> {
| ^^
note: ...but the lifetime must also be valid for the lifetime 'b as defined on the impl at 24:9...
--> $DIR/trait-impl-of-supertrait-has-wrong-lifetime-parameters.rs:24:9

LL | impl<'a,'b> T2<'a, 'b> for S<'a, 'b> {

= note: ...so that the types are compatible:
expected T1<'a>
found T1<'_>
error: aborting due to previous error
