Macro define_html_macro 

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

Creates a custom html! macro with the given settings. The generated html! macro calls html_with_config under the hood.

// This creates a macro called `my_html!`
define_html_macro! {
    /// This documentation comment will get added to the generated `my_html!` macro.
    my_html!
    real_dom = (),

    // Optionally configure the path to the underlying macro to call.
    calls = html_macro::html_with_config,
};

// `my_html!` can now be used to create `VirtualNode`s.
let node: VirtualNode<()> = my_html! { <div>hello world</div> };
