error[E0405]: cannot find trait `Nonexist` in this scope
--> $DIR/unboxed-closure-sugar-nonexistent-trait.rs:1:8
|
LL | fn f<F:Nonexist(isize) -> isize>(x: F) {}
| ^^^^^^^^ not found in this scope
error[E0404]: expected trait, found type alias `Typedef`
--> $DIR/unboxed-closure-sugar-nonexistent-trait.rs:6:8
|
LL | fn g<F:Typedef(isize) -> isize>(x: F) {}
| ^^^^^^^^^^^^^^^^^^^^^^^ type aliases cannot be used as traits
|
help: you might have meant to use `#![feature(trait_alias)]` instead of a `type` alias
|
LL - type Typedef = isize;
LL + trait Typedef = isize;
