Macro classes 

classes!() { /* proc-macro */ }

This macro provides a convenient way to create Classes.

The macro takes a list of items similar to the vec! macro and returns a Classes instance. Each item can be of any type that implements Into<Classes> (See the implementations on Classes to learn what types can be used).

Example

let conditional_class = Some("my-other-class");
let vec_of_classes = vec!["one-bean", "two-beans", "three-beans", "a-very-small-casserole"];

html! {
    <div class=classes!("my-container-class", conditional_class, vec_of_classes)>
        // ...
    </div>
};
