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>
