error[E0790]: cannot refer to the associated constant on trait without specifying the corresponding `impl` type
--> $DIR/issue-58022.rs:4:25

LL | const SIZE: usize;
| ------------------ `Foo::SIZE` defined here
LL |
LL | fn new(slice: &[u8; Foo::SIZE]) -> Self;
| ^^^^^^^^^ cannot refer to the associated constant of trait
error[E0277]: the size for values of type `[u8]` cannot be known at compilation time
--> $DIR/issue-58022.rs:13:41

LL | fn new(slice: &[u8; Self::SIZE]) -> Self {
| ^^^^ doesn't have a size known at compile-time
|
= help: within `Bar<[u8]>`, the trait `Sized` is not implemented for `[u8]`
note: required because it appears within the type `Bar<[u8]>`
--> $DIR/issue-58022.rs:8:12

LL | pub struct Bar<T: ?Sized>(T);
| ^^^
= note: the return type of a function must have a statically known size
error[E0423]: expected function, tuple struct or tuple variant, found trait `Foo`
--> $DIR/issue-58022.rs:15:9
|
LL | Foo(Box::new(*slice))
| ^^^ not a function, tuple struct or tuple variant
error: aborting due to 3 previous errors
