E0277 suggestion for changing parameter type to a reference suggests a syntax error

[ydirson]

On the yew tutorial, starting from this working state I tried this change:

 -#[derive(Properties, PartialEq)]
-struct VideosListProps {
-    videos: Vec<Video>,
-    on_click: Callback<Video>,
-}
-
+#[autoprops]
 #[function_component(VideosList)]
-fn videos_list(VideosListProps { videos, on_click }: &VideosListProps) -> Html {
+fn videos_list(videos: Vec<Video>, on_click: Callback<Video>) -> Html {
     let on_click = on_click.clone();
     videos.iter().map(|video| {
         let on_video_select = {

This resulted in this build error:

   Compiling yew-tuto v0.1.0 (/home/user/soft/rustweb/yew-tuto)

   |                ^^^^^^ the trait `ImplicitClone` is not implemented for `Vec<Video>`

help: consider borrowing here
   |
16 | fn videos_list(&videos: Vec<Video>, on_click: Callback<Video>) -> Html {
   |                +

For more information about this error, try `rustc --explain E0277`.

This produces a syntax error, a more correct suggestion would be videos: &Vec<Video>.
