| error[E0277]: the trait bound `(): ~const Tr` is not satisfied in `fn(()) -> i32 {<() as Tr>::a}` |
| --> $DIR/const-closure-trait-method-fail.rs:18:23 |
| | |
| LL | const _: () = assert!(need_const_closure(Tr::a) == 42); |
| | ^^^^^^^^^^^^^^^^^^^^^^^^^ within `fn(()) -> i32 {<() as Tr>::a}`, the trait `~const Tr` is not implemented for `()` |
| | |
| note: the trait `Tr` is implemented for `()`, but that implementation is not `const` |

| LL | const _: () = assert!(need_const_closure(Tr::a) == 42); |
| | ^^^^^^^^^^^^^^^^^^^^^^^^^ |
| = note: required because it appears within the type `fn(()) -> i32 {<() as Tr>::a}` |
