error[E0225]: only auto traits can be used as additional traits in a trait object
--> $DIR/issue-32963.rs:8:31
|
LL | size_of_copy::<dyn Misc + Copy>();
| ---- ^^^^ additional non-auto trait
| |
| first non-auto trait
|
= help: consider creating a new trait with all of these as supertraits and using that trait here instead: `trait NewTrait: Misc + Copy {}`
= note: auto-traits like `Send` and `Sync` are traits that have special properties; for more information on them, visit <https://doc.rust-lang.org/reference/special-types-and-traits.html#auto-traits>
error[E0277]: the trait bound `dyn Misc: Copy` is not satisfied
--> $DIR/issue-32963.rs:8:20
|
LL | size_of_copy::<dyn Misc + Copy>();
| ^^^^^^^^^^^^^^^ the trait `Copy` is not implemented for `dyn Misc`
|
note: required by a bound in `size_of_copy`
--> $DIR/issue-32963.rs:5:20
|
LL | fn size_of_copy<T: Copy+?Sized>() -> usize { mem::size_of::<T>() }
| ^^^^ required by this bound in `size_of_copy`
